If you’ve spent any lengthy amount of time on the Internet, you’ve probably heard of open source software but might not have fully understood what it is and why it even exists. This article will describe this recent phenomenon and describe some of its benefits for the software using community.

In a nutshell, open source software is software made by everyone - for everyone. The hopes behind its development is that through its open access, it will evolve into something that represents the true desires of computer users. Through a wide network of user involvement, the software in question is enhanced and debugged without costs or administrative politics.

Have you ever thought about networking your computers at home? If you have a small collection of computers around the house (and a small collection of computer users), you can connect each one of those computers to one another and share data, software, and hardware including a single Internet connection. There are many creative uses for home networking, however it’s an ideal situation when upgrading each computer to the same capability is financially out of the question. On a home network, each computer has access to the equipment of the better machine in the group as if that equipment were their own.

Connecting computers with either an Ethernet cable or a Wireless connection can create a home network. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it’s used to communicate with every computer that’s connected to it.

Adware is advertising delivered directly to your computer.  Generally, a program puts ads on the screen at some regular interval.  In some cases, this program can be installed without the user’s knowledge, but not always.  Many programs clearly state on install that “this program is supported by advertising, and if you turn off the advertising, you also shut down the program.”

Adware tends to be a “grey area” in the malware family.  Yes, it can run without the user’s knowledge, and yes, it can bog down the system (especially when the adware program goes online to retrieve new ads to display).  At the same time, adware is generally more open about what it does, giving the user the choice to install the program the adware is attached to.

Adware is most often tied into Internet Explorer somehow.  The ads that appear are browser windows.

At some point, your needs are going to outgrow the capabilities of your computer. You may find yourself in need of more hard drive space for all those videos and mp3s that you download, for example. Or maybe that cool new programming language you’ve been dying to try requires more memory than what your computer currently has. Unless the activities on your computer are restricted to pure textual output (plain text files), your computer is going to get filled with a lot of “stuff” - stuff that can overfill a PC’s capacity too much for the computer to function well.

The problem is that while upgrading a computer is always an option, technology advances so fast that newer products (such as memory chips, new drives, etc.) aren’t always compatible with the machines that we own. This is a common occurrence when newer pieces of hardware require the programming of a newer operating system. Sure, one could upgrade the operating system to accommodate the demands of a new piece of hardware, but trouble starts when that new operating system requires new hardware in return. If we’re not careful, we could end up replacing almost every hard and soft part of a computer that we own - all in an effort to upgrade! Upgrading in this fashion is not only silly to do so, it’s also costly - more costly than simply buying a new computer.

In a previous article, we introduced automating some tasks with MS-DOS batch files. In this article, we’re going to introduce programming and describe how it can be used to control the way your computer works. Normally, computer novices aren’t interested in controlling the computer. New computer users are typically interested in learning more about how the thing works. However they may be surprised to learn that programming increases computer knowledge as a whole and it can help to diminish the fear associated with using a new computer.

Programming a computer is creating a sequence of instructions that enable the computer to do something.1 The people who program computers (called programmers) use a programming language to communicate with a computer. You might have heard of some of these languages in the past such as Visual Basic, C++, or Fortran. There are hundreds of other programming language and neither one is better than the other. Most of them are capable of performing the same tasks and achieving the same goals. A programmer chooses one language by a simple preference.

Computer errors can pop up when least expected, they can cause the entire system to suddenly shut down, and they can inadvertently corrupt data to the point where it can’t be deciphered. Although they can’t always be avoided, it’s important to remember that computer errors can be corrected. The key is to understand what computer errors are, understand what they mean when they show up, and understand how to minimize their occurrence in the first place.

Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They “operate” whenever there’s a conflict among commands. Remember that computers essentially run off of a series of commands and it’s usually a smooth process. But when one command conflicts with another command - or when one command asks for a process or information that isn’t available, the computer returns results that aren’t useable. That’s an error.

It’s the ultimate nightmare for a computer user—the idea that someone outside the computer can take over.  The official “technical” term is Remote Administration, but hackers are more likely to use the word Backdoor.

With Windows XP, remote administration comes pre-installed.  Windows XP has an option called Remote Assistance, where an XP technician can “remote in” and take over your computer.  The remote tech has as much control over your system as if he was sitting there at the keyboard.

The hackers predate Microsoft by several years.

It isn’t fair, but buying a computer is just plain easier for some than it is for others. Those who’ve purchased and used a computer in the past already have an idea of what they need in a new computer. But those who are new to the computer world could get lost in the myriad of choices available.

The short answer to “What should I buy?” is “The best.” Of course that answer is extremely subjective because “the best” to one person is certainly different to another. Our definition of “the best” is the fastest and the biggest, but even that leaves the computer newbie confused. Here’s a quick rundown of what the computer novice should do and why.

“Warning!,” the email screams.  “There’s a new virus going around, and Microsoft says it’s the worst one yet!”  After this amazing bit of hype, the email continues with “Once this virus infects your system, it will delete all the files on your hard drive, reset your computer clock, and make your screen only show green and black!”

Anyone who has made it this far is then asked to “forward this virus warning to everyone you know!” and “Delete any emails you get with the title “Have a nice day!’

This email has all the signs of a virus hoax.

If you’re familiar with MS-DOS at all, you’ll recall that it’s a command-driven operating system that performs functions issued at the C:> prompt. The only way to get an MS-DOS computer to do something was to type a command at this prompt and if you can imagine, it was a rather cumbersome way to use a computer.

As an example, to load up Microsoft’s simple editing program, you had to type the name of the drive that the program was on, the directory that the program was in, and then the name of the program. So if Microsoft Edit was in a directory or folder named “Process,” you could start the program by typing, “C:>process\edit.com” Then, and only then would the program load up for use.
