“I am looking for a new computer to use at home and don’t know what all the “specs” mean. Can you please explain these terms and numbers so I will know what computer I need?”
Yes, all those numbers and letters can be confusing. Let’s get started.
The first one you are likely to come across is the processor speed of the computer. The CPU (processor) is one of the most important components in the computer and determines how long it takes to perform tasks, such as opening windows and downloading files from the internet. Processor speeds are measured in Hertz and now commonly in the GigaHertz size, therefore you will see something like 2.0 GHz. This is amazingly fast compared to 10 years ago when most computers were using 150 MHz (MegaHertz). Generally, processor speeds are so fast now that the naked eye can’t tell the difference between a 1.5 GHz and 3.0 GHz. Unless you require super-speed to process graphics or play the latest games, the processor speed shouldn’t be much of an issue.
The storage space of the Hard Drive is another important component to consider and determines how much “stuff” you can have on your computer. Your operating system and all other programs that you install, as well as your personal documents and pictures, are all stored on the hard drive. A large hard drive means you don’t have to worry about running out of space for all those digital camera pictures you want to keep. Hard drive storage is measured in GigaBytes and the common size (for the moment) seems to be between 80 and 120 Gb. For most of us this is plenty of storage space, but there seems to be no limit to the size of hard drives being served up.
RAM (Random Access Memory) is the next most important component. The memory allows you to access the contents of the hard drive in any order which means that the larger the size of the RAM, the faster your processor can access and display your programs and data. RAM is measured in MegaBytes and GigaBytes and the minimum you should have is 512 Mb. Ideally, you want to have 1 Gb of RAM in your computer.
Less important, unless you are a gamer, is the Graphics Card. The graphics card determines how well your monitor displays pictures, videos, and animations. At a minimum your graphics card should be 128 Mb.
Another thing you need to consider is the CD or DVD drive for your computer. Make sure that you get a Re-Writable (RW) drive so you can keep copies of your important documents and pictures. A DVD-RW has become the new standard and allows you to save much more data on each disc.
You may also want to consider how many USB ports your new computer should have. USB ports are where you plug in your printer, scanner, camera, mouse, and other devices. Your computer should have a minimum of 4 USB ports but the more the merrier.
And last but not least, is the Monitor. There are two main types of monitors available now: CRT which is available in both standard and flat screen and LCD (flat screen). LCD screens have dropped in price considerably over the last few years and take up much less room on your desk. The most common monitor size (for today) is 17 ” but you can also get monitors in much larger sizes.
