hard disk
A: What about things like power and speed, that sort of thing? What do I look for?
B: Well, power depends on speed and capacity-the speed of the processor and the capacity of the memory and the hard disk.
A: The speed of the processor?
B: How fast the computer processes data. Speed is usually given in megahertz or gigahertz. The faster the processor, the more powerful the computer.
A: And capacity?
B: How much storage space there is in the computer. Capacity depends on how much memory there is, how big the hard disk is. You measure RAM and video memory in megabytes. You’ve also got cache memory. That’s in kilobytes. Always look for the highest numbers.
A: What about the hard disk?
B: Hard disk capacity is in gigabytes. Get a big hard disk for multimedia. Audio and video files use enormous amounts of space. Once again, the higher the numbers, the more powerful the computer.
