In this article, I want to talk a little bit about two computer terms that I see people confusing or demonstrating that they don’t understand completely.  People often use the two interchangeably or consistently use the wrong one. These two terms are “cancel” and “delete.”

Let’s start with “delete.” To delete something is the process of taking something such as a file, like a Word document or photograph, and removing it.

The process generally involves moving it to the trash on a Mac or the recycle bin on a Windows machine and emptying the trash or recycle bin. The emptying part is what is actually deleting it.

When you delete a file, in most cases for most people, it’s gone. Technically, it’s still there but has been marked as available space on the drive — think of painting over a mark on a wall — it’s hidden but not technically gone.

Whatever space the file that has been deleted was taking up is marked as available. Until some other file comes along and is saved in that spot, or part of that same spot, the file is technically available and can be recovered with the right program.

However, as far as most people are concerned, once the recycle bin or trash is emptied, the file is gone for good. Until you empty it, it’s still available for you to pull back out and retrieve.

Another example of how to use the word “delete” correctly is when you delete not a file, but text.  For example, if I decided I didn’t want this specific sentence in this article anymore, I’d delete it with the “delete” or “backspace” key on my keyboard.  Again, as with deleting a file, this is the process of removing something.

In most writing programs (including word processing programs such as Microsoft Word, or email programs such as Mozilla Thunderbird, etc.) you can restore words you’ve deleted if you use “undo” to reverse the last thing you did.

Some programs may let you undo more than once, stepping back through each change you made, but in most or all cases once you close the program, any words you’ve deleted from your document are gone for good unless you’ve saved them in a different file.

What I see people doing sometimes is use the term “cancel” or “delete” inappropriately. Deleting is the process of taking information on a computer and getting rid of it. It is not the process of closing a window.

I have seen a lot of people refer to closing a window or getting rid of an error message that has come up as “deleting” it. That’s not deleting. If you close a window, you’re simply closing a window.

I’ve also seen people refer to closing a window as canceling. I’ve also seen people refer to deleting an item as canceling it. That’s not the correct terminology.

Canceling is when you have a process that has been started and you “cancel” that process. You stop it from continuing, or interrupt it in other words.  It takes you back to where you were immediately before the process.

What do I mean by that? Let me give you an example. Let’s say you in a word processor, like Microsoft Word. You’ve written something, and then you close the program without saving.

What’s going to happen? Traditionally, the program will pop up a window or dialog box that presents you with some options. It will say something along the lines of, “You’re trying to close, and you haven’t saved yet. Would you like to save, cancel or continue without saving?”

The wording does vary from one program to the next, but something along those lines is what you might see in the situation where you’re trying to close without having saved yet.

Let’s just say the phrasing is, “Do you want to save the changes you made? Your changes will be lost if you don’t save them.” Then you’re presented with three buttons: don’t save, cancel and save.

What would happen in this situation if you tried these different buttons?

If you don’t save, it will simply close the program or window without saving it, and you will lose whatever work you’ve done since the last time you saved. If you click save, it will save the file, and probably ask you for a file name if you haven’t saved it before.

The other option is to cancel. Cancel would cancel the process of closing and take you right back to where you were before you started to close the window.

At that point you could continue writing, you could save and close or you could decide you’re going to close anyway and that you don’t care about saving. Then it would present you with the same three options, and you would be able to hit “don’t save.”

What I’m trying to say here is that if you are presented with a cancel option, it doesn’t mean it’s going to delete anything.

It just means that whatever process you’re in the middle of, in our example exiting a program, it interrupts that. It takes you right back to where you were immediately before that.

It’s not correct to refer to closing a window as canceling it. It’s not correct to refer to deleting a file as canceling it. Canceling only applies to a situation where you’ve started a process (a series of automated steps) which you have the option of cancelling before all the steps are completed.

If you want to get technical, if you hit the cancel button, it does close the little window with the question in it (the little window with the question in it is referred to as a “dialogue box” because it’s asking a question and waiting for a response — trying to have a dialogue with you).

This is probably where the confusion comes from for a lot of people. Closing the window is not correctly referred to as canceling even if sometimes canceling something will close a window.

I hope that makes sense. I know it’s a little confusing sometimes because you see these words out of context, and you don’t fully understand how they work and relate to each other.

I hope that makes some sense and will help you use those computer terms more accurately in the future so you can recognize and understand what people are saying when they’re using them correctly around you in the future as well.

In this audio lesson & transcript, I’m going to take a question from Mark. He writes and asks, “What’s a flash drive?”

Transcript of computer lesson begins:
A flash drive is a type of storage device for a computer. A storage device is the broad or general term for anything that is used to store data or files.

A hard drive in your computer is a storage device. An old floppy disk is a storage device. A CD-ROM or DVD is a storage device, and so is a flash drive.

A lot of people call flash drives by specific brand names. They think that is the correct name for them. Sometimes they’ll refer to them as a thumb drive, jump drive, go drive, key drive or any number of things. These are actually all brand names or partial brand names that people have mistakenly thought was the correct general term for that type of device.

A flash drive is a little piece of solid state storage. That means there are no moving parts. From the outside, it looks basically like a uniform block.

If you dig inside of it, there’s what’s referred to as a disk, but it’s not a disk shape, unlike a hard drive. Inside of a hard drive, there is a physical disk that looks like a disk. Even with floppy disks, I’ve heard people over the years say they aren’t disks. Technically they are. It’s square on the outside, but if you rip open an old floppy disk, you’ll find a disk inside. It would actually flop. It’s not rigid.

Basically, a flash drive uses something called flash memory. That’s solid state, so there are no physical moving parts unlike with a hard drive. That has a physical disk, like I mentioned, which spins much like an old record or a CD does when it’s playing.

That has a little thing called a read/write head that moves around and reads information from the disk and writes information to the disk. There are a lot of physical moving parts.
That uses more electricity than something that’s solid state. It also usually takes up more space than something that’s solid state. The big advantage of flash memory is that it’s very small and lightweight, and it doesn’t use much power.

You get these little devices that can store an increasing amount of information, or data, on them. They only take up a very small amount of room.

Any mobile device like an iPhone or any smartphone typically has some kind of flash memory in it. It wouldn’t make any sense to try to put a miniature hard drive in them. While there are hard drives that could fit in there, it would use way more battery power and run the battery down really fast.

There’s also an increased chance of damage to the disk and loss of files by impact. One of the liabilities of the hard drive is that because it has spinning and moving parts, if something hits it or it gets dropped, it can damage the drive, and you can lose files.

There are safeguards in modern hard drives that make it so they very rapidly will stop the disk spinning to minimize the risk of that damage, but it’s still one of the downsides of them and one of the reasons they’re not used in mobile devices.

The big advantage with flash drives is that they’re very small, light and portable.

In terms of dollar per megabyte or dollar per gigabyte, they are significantly more expensive than hard drives. The difference in price is getting less and less as time goes by, and you’re getting more and more storage space on these little flash drives.

I remember probably in 2002, I spent something close to $400 on a 1 gigabyte flash drive. These days in 2011, not a decade on from them but getting close, I don’t think you can even get a 1 gigabyte flash drive because it’s such a small amount.

The smallest amount you can get is at least 8 gigabytes. I’m not sure. I haven’t looked at this recently. It may be 16 gigabytes by this point. You can get that for a few dollars. That’s just how it is. It’s pretty crazy, but that’s a pretty typical thing with computers.

I hope that makes sense. It’s basically another method of storing files. Typically, you can just plug flash drives into a USB port on your computer and drag and drop files. You’ll be able to then unplug it, plug it into another computer, and it’s a way of transferring files back and forth. It also is a way you can back up your files to make a spare copy of them to protect them.

That’s pretty much what a flash drive is.

You might have heard of them as jump drives, thumb drives, go drives or what have you, but those are all examples of flash drives. It’s not, in other words, the generic term for a flash drive.

Basically, that’s what a flash drive is. It’s a small storage device that’s easily carried around. You can put it in your pocket, plug it in, move files on and off a computer, unplug it, and put it back in your pocket. I hope that makes sense.

This computer question comes from Mahakali Ramesh Kumar, who writes:

“Dear Worth Godwin,

I want to know what is Bookmark in internet or in computers.

Thanking you,
Yours faithfully Mahakali”

TRANSCRIPT BEGINS:
That’s a pretty simple thing to answer. A bookmark is sometimes also known as a favorite, although originally it was known as a bookmark in most web browsers. Those are the programs you use to navigate around on the internet.

It’s really Internet Explorer that refers to them as favorites. I think they did this originally because they were concerned about avoiding copyright infringement. I’m not positive about that. At any rate, a favorite or bookmark is the same thing.

When the web was created in the early to mid ‘90s, the way we thought about it is like pages like pages in a book. If you have a book you’re reading and you want to get back to a page in that book, what do you do? You bookmark it. It’s the same basic idea.

A bookmark is a way of getting back to a page on the internet that is located on some site on the internet. You just want to get back to it, so you bookmark it.

You do this typically by going to the Bookmark menu. Sometimes there may be a button on the toolbar toward the top of the window that has a little plus symbol on the button. Whatever way you do it, you hit the button or go to the menu that says “Bookmarks” and hit the option that says “Add bookmark” or “Add favorite,” in the case of Internet Explorer.

As a side note, I strongly recommend that you do not use Internet Explorer, for security reasons (instead you could use Google Chrome, or Mozilla Firefox for example).
Basically, you click “Add bookmark” or “Add favorite” as the case may be.

It creates some record of where you were. It will put in the name of that page as the description, although you are usually given the opportunity to change it to a potentially more descriptive or memorable name if you want to.

Then it gets added to that menu. In some cases it gets added to a horizontal bar called the bookmarks bar toward the top of your browser window. By going back to the menu or to the item on the bar, you would click it, and it would take you back to the page.

That’s basically what a bookmark is. It’s not a really complicated concept, but hopefully that makes sense and will help you get back to the pages you want to get back to in the future. It’s very useful.

I have found that there is a fairly surprisingly high number of people who do not use bookmarks or don’t know how to use bookmarks. It’s no criticism whatsoever. I hope that helps.

I received a computer question by email from a subscriber named Willa Valdez, who is wondering what I think about Ubuntu and Open Source software in general. Here’s her question:

“Dear Worth,

Mahalo Nui Loa for your Newsletters. Your computer lessons have helped me tremendously.

I am thinking of purchasing a netbook. They both have the operating system Ubuntu (latest version) already installed. I am a newbie when it comes to Linux but I am curious about how how this system works. I installed Ubuntu via WUBI along side VISTA, however, my computer would freeze when I chose to boot with Ubuntu. I was able to boot with Ubuntu a couple of times and liked the Gnome desktop. Unfortunately, some of the applications I use were not supported i.e. Skype. I did not delve into learning the Command Line just yet.

I would appreciate your thoughts on Ubuntu and your general opinion on the Open Source concept.

Again, thank you for expertise and assistance.

Aloha,

Willa Valdez”

Below is a partial transcription of the audio:

What do I think about Ubuntu and open-source? There are a few things. Let’s start with some definitions. Not everybody is familiar with Ubuntu. A lot of people think it’s called Abuntu, but it’s Ubuntu. It’s an African word.

Ubuntu is a version of Linux. Linux is a type of operating system that is an alternative to the more mainstream Microsoft Windows and the mainstream, but not quite as mainstream as Microsoft Windows at least in terms of widespread use, Mac OS X. Linux, Mac OS X, and Windows are all examples of operating systems, which is just the underlying software that’s needed to let your computer run and allows everything else to work.

Linux is a project that has been going on for quite some time. It’s what is called an “open-source project,” and it’s part of the open-source movement.

Open source actually goes back to the roots of making software originally. The most widely used software is Microsoft Windows, and it’s developed by a particular company, which is Microsoft. That is not a value judgment but just how it is

That’s what you could call a closed-source program. It’s software that was designed by a particular company, and as a result, it’s guided a bit by the company’s agenda. That’s not some kind of “Microsoft is evil” kind of statement. Every company has some degree of agenda or plan.

Open source is an alternative to that. The way it works is you have a community of people from all over the world collaborating to find ways of improving the software and fixing problems.

They find problems in the first place. Person A finds a problem. Person B finds a solution, and then Person C implements the solution. That is perhaps how it might work. Basically, the whole idea is to work together to make the best software you can.

I think open-source is great. I don’t use it exclusively. There are some people who are very militant about it. It’s kind of cool in a way too, I should say. There are some people who insist on using only open-source software for ethical or moral reasons, but I don’t go that far.

I think open-source is great. It’s something that people can use in a lot of cases.
I try to recommend it in a lot of cases. Mozilla Firefox is an example of open-source software. Open-source generally, if not in every case, is free. They don’t charge for it, just like with Mozilla Firefox.

Mozilla Thunderbird, the email program I recommend for Windows users particularly, is another open-source program. I recommend using the OpenOffice program for Windows or NeoOffice for Mac.

Open-source is essentially just a collaboration of people from all over just trying to work together in a very altruistic kind of way to just try to make the world a better place through better software. That’s the principle behind it. Linux is an example of open-source software, and Ubuntu is one specific version of Linux, for there are many.

One of the downsides for Linux and one of the reasons that it has not been adopted widely is the fact that, on average, until recently, it has been significantly harder to use than Windows. I think Windows is harder to use than the Mac software.

It has really been something that was mostly used by the techy people who are really into tinkering. They want to be able to tinker with the computer as much as possible, and they’re perfectly happy with things not being set up and ready to go out of the box.

Ubuntu is one of the versions of Linux that has made a lot of strides to improve the situation and make it a lot more accessible to people. It’s not completely there, but certainly if you want to try it, I don’t want to discourage you.

A lot of the really inexpensive and lightweight laptops that have become popular over the last couple of years, and Netbooks particularly, are shipping with Ubuntu or some other version of Linux on it. It cuts down the cost of not just inexpensive hardware but also inexpensive software by providing this free open-source software.

It’s fairly easy to use the basic stuff now. You can get around. It’s usually going to come preloaded with most of the basic software you need, but you’re still going to run into issues.

I don’t have a copy of Ubuntu installed on any of my computers. I’ve played with it before, and it’s one of those things on my to-do list. When I theoretically start having free time to play with stuff like that, I definitely want to try it out because it has apparently become much better. I’ve seen a little bit with a couple of clients, and it has definitely come a long way.

It’s something that may not be for everybody yet, but it’s something that’s very cool. I really like the principles and ideals behind open-source software. It’s definitely something worth checking out.

One really neat thing about things like Ubuntu is that there is an easy way for you to try it if you want. They have something called a Live CD as you can do with a lot of Linux installations.

You go to their window and download an image of a CD. It’s stored in a file, and then you can use disc-burning software. They’ll have instructions on the website on how to do this.
You can burn a Live CD [or make a bootable USB drive] that allows you to start the computer and run Linux. You don’t have to worry about actually installing it, replacing anything, or trying to install it side-by-side with Windows, which doesn’t always work as Willa has discovered.

Those are some general thoughts about it. Hopefully that makes sense and answers some of your questions. Ubuntu and other versions of Linux are just going to keep getting better and better over the coming years.

I am a little bit hesitant about telling people to just rush off and start using it. If you’re a little more of an adventurous computer user and you want to try things out, then it’s definitely something worth trying.

I definitely support the concepts behind it, and I think that open-source software in general is a great thing. I’m actually using some to record this audio. WordPress is blogging software that I use for my websites many times. That’s free. It’s open source, and I highly recommend it.

Open Source is a great thing. I hope that makes sense and answers your questions.

This time I’m going to take a question from someone who asks, “What is grounding? I’ve heard it phrased in so many places but don’t know what it is.”

This refers to draining off excess electricity. That’s basically what it’s about.

I’ve talked about how it’s important for someone working on the inside of a computer or any kind of electronic device that they be grounded.

If I work on a computer, take it apart and am upgrading or repairing it, any time I have the case open and am working in the inside of it, I’m always making sure that I’m grounded. The way I do this is that I have a special mat. It has a wrist strap attached to it. Then the entire mat and wrist strapped are attached through a conductive cable to an outlet where I plug in.

You may have noticed that with many, but not all, electrical devices, the power plug has three prongs. The third prong is the ground. The other two are the positive and negative poles that allow the current to flow and create a circuit. It goes in a circle. Then there’s the third prong, and that’s the ground.

On any modern building that’s been wired properly, that third prong is a separate wire. They all essentially go together and eventually have some connection that goes down into the ground, hence the term “grounding.” That drains off excess current. That’s basically what’s going on. For electronics to operate properly, they need to have that excess current bled off.

In terms of static electricity as opposed to the electricity you get from your power outlet, static electricity is generated by moving your arms around, for example. As I’m recording this, I’m gesturing with my hands. That makes no real sense since no one is seeing me when I’m doing this, but I’m still talking with my hands. As I’m doing this, it’s generating static electricity in my body.

If I went and touched a piece of electronics that wasn’t shielded properly, like exposed electronics on the inside of a computer, there would be a static discharge. Whatever the difference is between the charge in myself and the charge in the electronics, when I touch it it’s going to go through. If I’m not grounded, it’s going to go through the electronics and could damage it.

One way to think about this is almost like water pressure. Electricity and water are kind of similar. I like to think of them as being very similar, at least in a metaphorical or analogy way.

Water always flows downwards. It goes down to the lowest point. That’s essentially what electricity does. It always goes down the path of least resistance. It tries to go to ground.

By grounding myself and having this wrist strap on me, the wrist strap is conductive. It conducts electricity, and it’s attached to my skin directly. Everybody’s skin is conductive, so as my body generates that static electricity, it drains right on out of there like water flowing down to the lowest point.

The more static electricity in me, it’s almost like the water pressure building up. Too much pressure in a pipe could potentially burst the pipe. If there’s enough water pressure going through there and nowhere for it to be released, it could burst and damage the pipe.

In our analogy, that’s a circuit. It could be a circuit in a computer or a circuit board that contains many circuits. Those circuits can be burst open by that surge of electricity that comes through from static electricity.

The third prong, the outlet my grounding mat is attached to, is attached to ground or earth. The excess current drains out. Essentially, that’s what grounding is.

How does this relate to the average person? Most people don’t really need to worry about it too much. The typical person is not going to open up their computer and work on the inside of it, I would hope. It’s not usually a good idea.

If you do ever have to do it, particularly if you’ve got a computer tech coming to you or you’re taking it to a shop to have it repaired or upgraded, you want to make sure they follow proper grounding procedures.

Some places will say that it’s good enough that they touch the case occasionally. This particular example really annoyed me when I saw it, but there was a particular place I went one time. The one person was working there picked up a circuit board. It was a motherboard, also known as a main logic board. Before she did, she made a not really valid attempt to ground herself by touching the plastic case.

Plastic, of course, is not conductive. Therefore, it doesn’t work to ground you. They touched the plastic case on a laptop that was sitting on a wooden bench. Wood is not conductive. Plastic is not conductive. The laptop wasn’t even plugged in, which might have provided some pathway for that static electricity to go to ground.

Because the laptop plastic case was nonconductive on a wooden nonconductive surface, when she touched that thing, it didn’t do anything. She did not ground herself. Then she handled the electronic, and that damages it. It may not break it instantly, but it will weaken it and shorten the lifespan of the electronic, so it’s really important.

How does this apply to you? You want to make sure people actually use grounding mats. At the very least, instead of a wrist strap that attaches to a mat, some places will use an ankle strap. That’s essentially the same thing, but it attaches to the ankle instead of the wrist. That’s just as good.

You want to make sure they’re doing something like that. If they’re not, your electronics are not going to be taken care of properly. When you take it in for a repair, they might be doing damage.

The other bit of advice I can give the typical user of a computer is whenever possible, try to use a power adapter with a third prong for ground. This is never really going to be an issue for a desktop computer. I’m not sure I’ve ever seen one, and if I have it’s certainly been many years, that did not have that third prong on it to ground.

Laptops, on the other hand, a lot of times come with a power adapter that only has two prongs on it. I’m thinking of some of the Mac laptops. A lot of times the MacBooks have a power adapter that you can pull off the end. It comes with a little square adapter that a two-prong plug flips out of.

That whole little flip out part you can actually pull off, and they provide you with an alternative cable that’s longer and gives you more length to get to the wall. It also gives you a third prong.

I would strongly recommend that if you have a laptop, whether it’s made by Apple or anybody else, if you have the option of choosing a two-prong or three-prong adapter, always use the third prong. It will also protect your laptop better than the two-prong.

Essentially, that’s what grounding is. It’s a way of draining off too much water pressure, so to speak. It’s a matter of having some conductive path that leads between you and the device to earth, or other words, to ground. It drains off the excess.

This protects electronics. Potentially in some cases, it can even protect the person if they’re working with electronics and happen to touch it. If it’s not grounded properly, it could give them a shock. In terms of repairing and working on the inside of it, it’s the static electricity you’re trying to drain. You’re trying to protect the computer and electronics rather than yourself.

Hopefully that makes sense. We gave you a few tips that can help you avoid potential problems and help you choose a good place to repair your computer.

Video Lesson Transcription Begins Here:


I want to explain the computer term “video card.” I’m answering a newsletter subscriber’s question about what a video card is. I’m going to explain to you what a video card is and what it basically does. I’m also going to give you a few suggestions on choosing the right video card for your computer.

I will not be going into specific makes and models of video cards because things change very rapidly. One of the fastest changing components in a computer is the video card because computers are putting greater and greater demands on it. Anything I could talk about that is specific to a particular make or model will be obsolete soon, so I’m not even going to get into that.

What I will do is give you the general ideas and principles that will always apply.

A video card is a piece of hardware. Hardware is the physical part to your computer, as opposed to software which is the nonphysical, intangible part of the computer.

A simple way I like to explain it is that hardware is like your brain, the physical part in your head that thinks. Software is like the thoughts in the brain. You can’t touch thoughts, but they’re there nonetheless and they make a difference.

In many cases, you have a video card that is a separate card. It’s thin and rectangular-shaped. It goes into a slot inside your computer. In other cases, you have what’s called an “integrated video card,” or it’s built into the motherboard or main logic board of the computer.

The ones that have integrated video or built-in video are usually not the best quality, and you won’t get the best performance out of the computer. There are a few reasons for this.

The video cards that are integrated are usually low-end video cards to begin with. It’s not always the case. Apple puts integrated video cards into their computers in a lot of cases, but depending on the make and model, they may or may not be a lower-end one.

That’s a generalization, but most of the time if you’re talking about a Windows computer with an integrated video card, it is a lower-end card and you’re potentially going to be sacrificing a little bit in performance. Part of this is because the video card itself is not the most powerful in the world.

Other times, it’s because the video card, which uses memory, borrows the main memory from the computer, so you can lose a quarter or more of your actual memory that it says on the box or label. You end up sacrificing a good chunk of it, so you don’t really get as much memory as you think you have or as much as the salesperson said if it’s an integrated video card.

All a video card really does is take the picture and put it on the screen. If you’re watching this on a computer, which I assume you probably are, it has a video card. You could be on an iPhone or something, and these have integrated video cards in them too.

It’s the same basic principle. The video card just takes the picture and puts it on the screen. It’s not just moving video but also all the desktop icons, your menu bars and so forth.

Then you have the higher-end cards. The cards that slot in separately are generally on a Windows computer because on the Apple side, they have integrated cards with most of the computers. Usually, they’re a little bit better quality than the integrated ones, or in some cases, a lot better quality than the integrated ones that you find on Windows computers.

The high-end Mac Pros do have separate cards that slot in. That’s partially because the cards that go in tend to be more beefy, robust or powerful than the integrated cards.

There is still a fairly wide range of quality. You have very cheap video cards and very high-end ones. Which one do you want to get? That’s a good question.

Again, with any of the ones that Apple is selling with their computers, you can fairly safely assume that it is going to be more than capable of handling the basic stuff that most people, the average computer users, are going to do. They don’t tend to put in cut-rate equipment.

On the Windows side of things, with a lot of the different brand names out there, this is not always the case. The low-end cards often make a fairly big sacrifice, especially if you’re running a newer version of Windows, like Windows Vista. It should be better with Windows 7, which is still forthcoming. Windows Vista does a lot better with a high-end video card.

You don’t need the highest high-end machine, but it’s helpful to have something other than the cheapest, least expensive, least powerful card. Something in the mid-range should be fine.

Who needs a really high-end video card? Someone who is going to be playing high-end games on the computer needs one. I don’t mean Solitaire. I mean a fast-paced, very complex, animated, fast-moving game with computer-generated images.

The games like first-person-perspective shooter games where you’re running around playing in a hostile environment tend to work better if they have a high-end video card. They’re going to look better. They will perform better. It’s not going to be slow. Someone who is a high-end gamer, of course, wants a high-end video card.

Generally speaking, if you play the latest, greatest games, you want to get the best video card you can possibly put in your computer. That’s the bottom line.

For someone who’s doing fairly high-end stuff with graphics or video editing, it doesn’t always make a big difference to have a high-end video card, but it can help. Someone who is doing CAD work or an architect perhaps might benefit from having a higher-end video card. They probably don’t need the highest end in the world, but it never hurts.

That’s basically what I want to cover. I can’t give you really specific advice about a particular make or model card because it gets outdated almost immediately.

The basic principle is that a video card is just a part of the computer. It’s a piece of hardware.

It puts the picture up on the screen and lets you hook your screen up. In the case of iMac or a laptop, it’s built in and internally hooked up to that video card, but you still have the screen hooked up to a card. Even something like a phone has a video card of sorts in it, and the screen is hooked up to it.

That’s what I wanted to cover in this lesson.

A lot of people are unwittingly publishing information about themselves online when they share photos and videos online. This information is revealed in something called “metadata” which you can think about as “data about the data”, or info about the information (data) in the file.

This information about the file can be something as simple and visible as the file name, but the information most people are talking about when they mention metadata tends to be more “hidden” inside the file.

One example is “ID3 tags” in MP3 files which hold the musician’s name and other information, another example is the data in a photo which can reveal mundane information such as the camera settings when taking the photo and the date, but also GPS location information revealing exactly where the photo was taken.

This information is visible in typical photo viewing and editing programs such as Picasa for Windows or iPhoto for Mac OS X. It also often is revealed automatically on photo sharing websites.

A file name could be thought of as the simplest example of metadata since it can be used to describe the contents.

However, many types of files contain more information stored inside a special part of the file. Common examples of files with metadata include music, photos, & video files.

In photographs and videos the camera or smartphone typically records GPS information about your location and this can end up visible to the world when you share those files online.

This may not be a problem with all photos or videos, depending on where you shoot them, but ones taken of your home reveal where you live and what kinds of things you own. In effect, you’re casing your own home for potential burglars.

Most cameras and phones that can record this information will have a setting to prevent saving location information to the image. Consider sharing your photos privately with family and friends instead of in public galleries. When uploading to any site, look around (under privacy on the settings screen for example) for a setting that lets you turn off displaying GPS location data.

I show you how to disable location services in one of the video lessons in my How to Use the iPhone App.

Listen to the audio above for the full Plain English explanation and understanding of metadata and how it can affect your privacy.

In this article I’ll answer a question sent in by a student named Daniel McClutchy who writes:

“Hi Worth:  Your CDs have helped a great deal to understand the internet and computer basics.

Thanks.

I have a question for you.  Can you explain what a torrent site is? I followed a recommendation of a co-worker and logged on to one.

My Kasperksy went crazy, not allowing me to access it.  Is this because they contain viruses?

Thanks, Daniel”

Well Daniel, I’m glad you’ve found my lessons to be a help; I always appreciate it when people take the time to let me know how they’re benefiting from my hard work!

So, let’s start off by explaining what a torrent site is, and then I’ll answer your question about whether they’re dangerous.

A “torrent” is short for “BitTorrent” which is a technology used to distribute files over the Internet.  Like any technology, it can be used positively or negatively.

Torrents can potentially speed up the downloading of large files (downloading is the process of copying a file “down” to your computer from another one, usually over the Internet — when sending a file it’s called uploading).

It speeds up downloads by basically chopping up (so to speak) a file into tiny pieces which can be sent in a “swarm” from dozens, hundreds, or even thousands of computers at once, each only having to send a small amount of the file.

While there are many legitimate uses for this, perhaps the most common use for torrents is to share pirated movies, music and other copyrighted files.

Now I’m not going to go into a moral lecture on whether or not it’s right to take other people’s content without paying for it, but I will warn you that there are a lot of risks involved in using the “torrent sites” you’re asking about.

Now as I said, there are many completely legal and legitimate uses for the BitTorrent technology, but when people talk about “torrent sites”, they’re generally referring to the ones using BitTorrent to distribute copyrighted material without paying for it.

Those sites you do need to be wary of. Let me explain why.

First off, many of those torrent sites are hosting ads from less legitimate advertising networks which tend to be used by “shady” sites such as gambling and pornography sites.

These ads are more likely to contain “malware”, which is software (including, but not limited to viruses and worms) designed to cause damage. Malware is written these days to make money by infecting computers, and so shady sites often do this as a cheap way to make money, and they apparently don’t care whether they cause harm!

So many torrent sites are capable of infecting a computer simply by you visiting it, especially if you’re not protecting yourself with good
Internet security software (such as Kaspersky) and by avoiding using the Internet Explorer web browser.

Beyond the potential risk of simply visiting a torrent site, many of the files a person might try to download from those sites are themselves
infected with dangerous malware.

It’s well known that Apple’s Mac computers tend to have far fewer threats than Windows computers do, but the biggest threats for Macs that I recall from the last few years have all come from downloading illegal copyrighted material from sites like these.

And it’s a far bigger problem for Microsoft Windows computers!

One study I’ve heard of says that as much as 47% of all “zero-day malware” (one of the most dangerous kinds) is distributed through BitTorrent!

Lastly, beyond the potential threats to your computer posed by torrent sites and other file trading sites, there’s a very real risk to your wallet.

The recording industry, including the film and music industries have been very aggressively pursuing people who do illegal file sharing and are happy to sue you for a lot of money if they catch you.

And believe me, they can afford better lawyers than you or I!

Internet Service Providers will often shut down your Internet connection if they detect you’ve been sharing files illegally, so there’s that risk too.

So my advice is to steer clear of torrent sites. There are plenty of inexpensive ways to listen to music and watch TV shows and movies online or offline without exposing yourself to the risks of file trading sites such as torrent sites.

I hope that makes sense, and helps.

Until next time, take care, and enjoy,

Plain English Simplicity for This Complex Modern World

Audio and video lessons also available via computer training podcast.

Here is one of my early video lessons (please excuse the video quality) where I use one of my Plain English explanations of computer terms — explaining what a hard drive is and what RAM is, and what they do in your computer.  Many people confuse those two terms with each other, and many people don’t understand either at all.

If this is true for you, it’s not your fault — it’s just never been explained to you in a way that you could relate to. Watch this video and both computer terms will finally make sense, even if you feel like the most basic computer user in the world:

In this computer question & answer audio lesson I’m taking a question from user brandang17 who asks:
“So because I have wireless internet an stuff with my phone when I turn WiFi on does that mean I am getting free Internet or am I still paying for it though my plan? Thank you”

Use the player to listen to the audio computer lesson where I’ll not just answer the question “Is WiFi free?” but give my usual Plain English explanation of what I’m talking about so everyone can understand the answer, even non-technical people.

Bottom line is, someone always has to pay for an Internet connection somewhere along the line, so whether you’re using a computer or a mobile device like a smartphone it’s not “free” even if you’re not paying to use the wireless signal. And while using WiFi on your phone may not count against any monthly limits on data that your phone plan offers, it doesn’t mean you won’t get charged the regular monthly fee for phone data (Internet) connections.

You may be able to cancel the data part of your phone service, depending on the details of your contract, however. If you do, keep in mind you’ll be limited to *only* using WiFi signals and so will be much more limited about where you can go online with your phone.

The following article is another except from Worth’s new book titled “How to Avoid 7 Common & Costly Computer Mistakes – Explained in Plain English” and follows from my previous post where I answered the question “Why Back Up?” and my post where I explained how to back up using incremental backup.

In this article I want to explain one general method for how to back up your computer, namely something called “cloning”.  I won’t repeat the many reasons why it is absolutely essential that you back up on a regular basis, but I will give you some recommendations on methods you can use to protect yourself, including information for both Microsoft Windows and Apple Mac computers.

First off, let’s define “cloning” backups.

Cloning refers to making an exact 100% copy of your computer’s hard drive, typically onto a second internal hard drive, or better, an external hard drive which is left turned off except during the backup process to minimize wear and tear and keep it more reliable.

Some people argue that cloning isn’t really a method of backing up, and while I agree the original reason it was developed as an option was probably to make it easier to upgrade to a new hard drive, it also can make a great way to back up your computer.

If done correctly, when you clone your computer’s hard drive, the clone should be “bootable”, which is to say, you can start the computer up from that drive in exactly the same way you normally start up with your computer’s main hard drive.

The benefit of having a bootable backup copy of your drive is that it minimizes downtime and expense. In some cases, you can start your computer up from the external drive and literally be up and running again in a minute or two.

Running your computer off the backup drive in this way is not a long-term solution, but if you’re waiting on a replacement drive or you’re waiting for a computer tech to replace the main drive after it fails you can at least get work done in the mean time and everything will be exactly the way it was as of the last time you cloned the drive.

Cloning your drive in this way can also save you money by minimizing the time spent by a technician repairing your Mac or PC.  In many cases the tech can simply take the external hard drive out of the case and put it into the computer in place of a bad hard drive, then put the new replacement drive into the external case.

This can take as little as 5-10 minutes to get you back up and running again, as opposed to potentially hours of time with the bill getting bigger by the minute doing it “the old fashioned way” by putting the replacement drive into the computer, installing Windows or Mac OS X, and restoring all the files from the backup and potentially (depending on how you backed up) also reinstalling each and every program such as Microsoft Word, etc. and getting everything manually configured exactly how you had it before.

Unfortunately, there aren’t a lot of options to create a hard drive clone like this for Windows. Mac OS X users are fortunate to have more options, but it’s still possible to do on pretty much any computer.

I have found a couple of programs that will duplicate your hard drive in this way for Windows, both of which are free (although there are a couple of caveats on this which I’ll explain in a moment).

The first program for Windows, which makes these 100% “cloned” copies is something called XXClone.  This is a completely free program which does a great job and which I use myself.  The only problem with this program is that it only works properly with Windows XP, and is unfortunately not compatible with Windows Vista or Windows 7. You can find this program by Googling “XXClone”.

Another option for Windows users that does seem to work with all versions of Windows is Seagate DiscWizard (formerly Maxtor MaxBlast).  Discwizard is available for free from Seagate’s website — just Google “Seagate DiscWizard download” to get the link.

The one minor hitch to this is that for it to run, it does require at least one of your hard drives to be either a Seagate or Maxtor brand drive (Maxtor was bought by Seagate a while back).

This isn’t a really big problem for most people because when you buy your USB drive, you can either buy a Maxtor or Seagate brand, which are pretty easy to find, or go to a local computer store and ask them to put a Maxtor brand hard drive into any USB case for you.

These brand drives are also extremely common in computers, so there’s a very good chance you already have one of them as the main internal drive in your PC. I’ve been using Maxtor and more recently Seagate DiscWizard (which is the exact same program with a different name) for years and have tested this out extensively and it seems to have no problems as long as one of the drives is Seagate or Maxtor.

On the Apple Mac side of things people have a few options, the main two being something called “SuperDuper!” and another called Carbon Copy Cloner. SuperDuper is inexpensive, CCC is free (but appreciates donations).

Both are good programs, but I’ve been using CCC for the better part of a decade now as my main backup program and so it’s what I recommend to my clients. Both programs work in the same basic way, so pretty much anything I say about CCC applies equally to SuperDuper.

Unlike Seagate Discwizard on the PC, CCC does not require any specific brand of hard drive, and unlike XXClone — which only works properly with one version of Windows — should work with any modern Mac. If you have an older Mac they also, the last time I checked, keep an older version of CCC available if you need it, but unless your Mac is several years old you should have no problem running the current version of CCC.

On either type of computer, the time it takes to complete the backup varies a lot depending on how much you have on your hard drive, and what type of connector (USB, Firewire, eSATA) you use for the external drive. To do a complete backup it can take anywhere from half an hour to several hours in extreme cases (this is only usually going to be the case if you have an extremely large number of big files such as video files).

But you can start it and walk away, so it’s not as bad as it sounds. This should be done at least once a month, maybe more frequently if you plan to make a lot of changes to the computer, like installing new software, or updating your system with a major update to Windows or the Mac OS.

One of the things I really like about Carbon Copy Cloner (which I believe is also true of SuperDuper, but which unfortunately does not seem to be an option for the Windows programs I’ve mentioned) is that you can actually combine cloning with the other main way to back up your files, known as versioned (or incremental) backup.

Basically CCC can give you the best of both worlds.  With this option turned on, it takes a couple of hours to do the first cloned backup, but then after that it can be as quick as 5 minutes. Because of this, I back up my main computer using CCC every single day as the last thing I do.  This way I know I have everything backed up, and it happens quickly and literally as easily as the flick of the power switch on my external drive.

As a side note, Windows users who might want the ease of backup enjoyed by Mac owners should keep in mind that all Apple Mac computers can run Windows and it’s possible to do this and have Windows backed up right along with the main Mac OS X files.  There are a lot of other benefits to using Macs, but that’s a topic for another time.

If you need more help, take a look at my easy video lesson course on backing up your computer, available for either Mac or Windows computers. In the lessons I show you step by step how to correctly set up use the programs I talk about in the article you just read.

An online scam that almost had me fooled – here’s a tip to protect you

A while back I wrote you about how a number of people had their Apple iTunes account broken into, and I mentioned how this most likely happened due to “phishing scams”.

Phishing scams, of course, are scams where a criminal tries to trick you into entering personal information ranging from username and passwords, to credit card numbers or other information that can be used for identity theft.

Knowledge is the most powerful tool you can use to stay safe. In this email I’ll teach you something about web site addresses which will help protect you against phishing scams and similar threats.  URLs (short for “Uniform Resource Locator” or basically, a website address) can be broken down into smaller parts which can help you understand how they work, which can help you stay safer online.

I recently opened an email which at first glance looked like it came from Amazon.com and was an order confirmation. It looked very official and for a half second, I was totally fooled, despite being very knowledgeable about these things.

[Update: I've added a new post to the blog where I show you the email and go over in plain English exactly how to was able to recognize the scam email - use the link to watch the video]

Now there were a number of things in the email which made me realize it was a scam, but the big tip-off  was that the links in the email didn’t actually point to Amazon.com, although I’m sure if I’d clicked them I would have been taken to a website designed to *look* like Amazon.

Understanding how website addresses work will help you avoid falling for that trick, and it can help make your life easier in general.
Let’s start with the term domain name. We’re not just going to talk about domain names themselves, but also “top level domain names” (TLDs) and “subdomains”.

Not everyone understands what a domain name is, exactly, and some people think they do, but actually misunderstand exactly what it is.  That’s OK — keep reading to make sense  of the computer term, and others related to it.

Phishing scams usually can only fool people if the person doesn’t understand how to read and break down the address of a website into it’s individual parts.  The scammers will make a website address that looks official if you don’t read it carefully or if you don’t understand how the addresses work.

If you can’t read the address properly and can’t tell a real address from a fake one, then you can get into real trouble.

Let’s take a look at the parts that make up a website address so you understand it better. We’ll use a real & legitimate website address as an example.

When you’re looking at a website address, it typically has a format something like the following (note – the example is not a link)

www.worthgodwin.com/computer-training-cds/

You’ll notice is has a few sections to the address, so let’s break it down into parts, using the above address as an example.

www — this is the “subdomain” and despite popular belief, it is optional, and also does not have to be “www”. “www” is by far the most common subdomain, but pretty much anything could be a subdomain, or you can even leave it off in most cases.
But the bottom line is you can set it to anything you want, including something potentially deceptive.

worthgodwin — in the above example, this is the actual domain name. Typically the domain name is the name of the business or organization that runs the site, or it is descriptive of what the site is about.

This has to be purchased, and has to be unique, so you can’t use someone else’s domain without their permission.

.COM — this is the “TLD” or top level domain name. .com is by far the most common, but there are many others. The TLD is supposed to give the visitor an idea what broad category the site should fit into.

.Com means commercial, (although many non-commercial sites use it) .org is some kind of organization like a non-profit organization, etc.

Each country has it’s own TLD, too, like .US for the United States, .UK for the United Kingdom, .IN for India, etc.

Many of the TLDs are pretty casual — i.e. you can use whatever you want, even if it’s not an exact match for your type of site.

But some of them are very carefully restricted, such as .GOV for US government, .MIL for military, .EDU for actual schools or universities, etc.

/computer-training-cds/ — the last part of the address above refers to a folder, just like a folder on your computer. This is normally used to indicate a specific section of the site, and in this case is the main page with information about my computer training CDs.

If you are setting up your own site, keeping it organized like this can help Google figure out what your site is about, and help you get the visitors you want.

So now that you have a better understanding of the individual parts of a web address, how does this relate to protecting against phishing scams?

Well, first off, anytime you see a link in an email, you can put your mouse pointer over it and see where the link will take you.  If the link doesn’t match the supposed sender, that’s a dead giveaway.

So if the email is supposed to be from Amazon.com, but the link actually points to someplace completely different, do not click on the link!

But some scammers get a little more clever with it and will make the link point to something like:

amazon.fakesite.com

See what they did there?

If you look at that with understanding of website addresses, you’ll see the fake address has Amazon in the address, but it’s the *subdomain* not the domain name!

That should clearly tell you that the site is NOT Amazon.com, but someone who doesn’t understand the difference could fall for that trick very easily.

And that’s the tip I wanted to share with you to help keep you safe.

One last thing — I mentioned you can put your mouse pointer over a link and leave it there for a moment to see where the link will take you.

On most email programs and web browsers, the link address will show up on the very bottom of the window in something called the “status bar”. If you don’t see the status bar at the bottom of your email window, look in the “View” menu and you should see an option to show or hide the status bar.  The exact location of this menu option varies from one program to the next, but it’s generally found in the View menu somewhere.

The one big exception to this is newer versions of the Mac OS X Mail program did away with the status bar and instead the address will show up in a “tool tip” which is like a little word bubble which appears after a second or two when you put your mouse pointer over the link.

Why not test this tip out with the links below.  The links take you to my website to a page where you can find out more about my easy video lesson CD course on Safe and Easy Email — included in the lessons is a lot more info on protecting yourself online (including video lessons showing you more like what I talked about in this article), plus simple basics of how to use email and more.

Here are the links to try out:

If you have a PC running any version of Windows:

Microsoft Windows How to Use Email Safely

If you have an Apple Mac computer running OS X:

Apple Mac How to Use Email Safely

When you put your pointer over either link you’ll see it points directly to my website and so is safe to click.

I hope that helps, and that you stay safe and have a great day.

Until next time, take care, and enjoy,

(scroll down for video lesson)

I’ve been meaning to write a post mentioning that I’ve set up my site to automatically add the majority of audio and video computer training which I post to this blog to my podcast, and show you how you can subscribe for free.

Podcasts, for those who don’t know, is a portmanteau (that’s the fancy way of saying ‘squishing two words together’) of ‘iPod’ and ‘broadcast’. They can be listened to not just on a computer, but also on iPods and other similar MP3 players, and you can have them delivered to you automatically.

Over time, podcasts have evolved into many different styles of audio program, and there are even video podcasts (or “vodcasts”). I actually set up a podcast and published a few episodes way back in 2006, but dropped the project because at the time I didn’t have an easy way to keep updating it and just had too much on my plate.

However, I recently added a plugin to this site which lets me update the podcast automatically, and I’ll be posting lessons to it pretty regularly now, so it seems like a good time to let you know how to subscribe and have a selection of my lessons delivered directly to your computer via iTunes. This way you can watch or listen on the go with an iPod, iPhone, iPad, or on your computer if you prefer.

I recorded a new video lesson to show you how to do this, which you should be able so see below. Note: you can adjust the volume using the little slider at the bottom of the video player, and make the video full screen using the square button in the lower right corner of the video during playback.

If you want to learn more about using iTunes, I do have a 2-disc set of lessons which go into the basics of iTunes, more in-depth on podcasts, managing your music and much more. Use the following links to learn more about my easy video lesson CDs on iTunes.

This latest computer question comes from Taj Abed who writes:

“Hello, thanks for information. I want to know about PC safety, please describe it to me. I really need to find out about it.”

This is a kind of general question and there’s just a ton of information I could cover that could help you keep your computer running more securely. What I did was give you four basic steps you can take to help increase your computer’s security.

This is by no means a comprehensive list, but I’ve taken the time to explain everything in Plain English with some comparisons to real-world things which should help it all make more sense to you.

In this latest audio lesson I answer a computer question from a subscriber named Frazer Ames who writes:

“Hi Worth,
I just read the article on your website regarding modems and video chat. One of the things I have never understood about computers is this; what exactly is a modem and what does it do? I thought they were an essential part of all computers and had something to do with the speed, but I’ve never really understood.

Thanks in advance

Fraser Ames”

To hear the complete Plain English answer to this computer question, just listen to the lesson using the player below. As usual, I’ll not just give a rushed answer to the question but make sure I explain the computer terms and concepts in a way that will just make sense, regardless of your computer skill level.
