A computer network is made up of a number of computers that have been configured to be able to share resources and information with each other. This is accomplished by using wires, like cable television does, or wirelessly, like a satellite receiver or a mobile phone does.

In computing terms, the word ‘memory’ is generally used to refer to RAM (Random Access Memory). RAM is put on chips which are attached to the computer’s motherboard. The data a computer holds in RAM can be accessed very quickly but is often limited. Early computers, in fact, had as little as one kilobyte of memory. This compares with the current average memory for PCs of two gigabytes, with many systems having more than that. Memory is one of the contributing factors to speed. If a computer runs out of physical memory it will create Read the rest of this entry »

When you purchase a piece of software for your computer, what you are actually buying is a ‘license’ to use that software. This license normally comes with conditions on it, such as a single-user license or a ‘family’ license which can be for up to five computers. Businesses often purchase site licenses, allowing them to use as many copies as they need in their office. It is normal for commercial software providers to use DRM (digital rights management) to limit software to licensed purposes. Licenses generally Read the rest of this entry »

If your computer is running slower than usual, it could be due to a number of different factors. One of the main causes of slow efficiency is program buildup. The more software you add to your computer, especially ‘background’ software that starts when you turn on your computer (like Quicktime or RealPlayer), the slower your computer will perform. You should only install software if you absolutely need it and trust the source its coming from. To check for unwanted startup programs, start your computer in safe mode by pressing F8 during boot up then delete unwanted services and disable wanted services from opening automatically by turning off the ‘run in taskbar’ option.To enhance system performance and eliminate slow efficiency due to program buildup, clean out your internet temporary files by going to tools, clicking options, then searching and deleting files ending in ‘.tmp’.

When the time comes to get rid of your old computer and replace it with a new one, you’ll need to be prepared for both digital and physical disposal. You’ll most likely want to transfer important files and other meaningful documents to your new computer. Use an external storage device, a USB drive, or a CD to save your old files, and then wipe your hard drive clean so personal and financial information can’t be accessed. If there is information that could be used by an identity thief stored on your computer, you might want to consider using a program that overwrites or wipes your hard drive clean repeatedly. Once you’re sure you have the information you want to keep stored in an external source and the data you don’t need erased or destroyed, it’s time to handle the physical disposal. You can benefit from selling, recycling, or donating your old technology. Read the rest of this entry »
