A computer's memory holds programs which are in active use. Eight megabytes is recommended as a minimum for running many of today's applications at acceptable speed. Hard disks store your programs and data. To handle today's large programs, a hard disk of at least 200 megabytes is recommended. For ordinary day to day tasks, a 14-inch color monitor will do.
Most computers come with at least one diskette drive.
Sound cards, speakers and microphones let you use sound effectively on your computer. When comparing prices, make sure you are comparing computers with similar prices. Sometimes prices do not include monitors or keyboards, which you will need to use your computer. Another important factor is the guarantee on your computer. Look not only at the length of the warranty, but at how quickly you can get service when you need it.
