Memory storage devices.
One of the main functions of the computer is to store information. There are many ways to do it. Memory storage devices fulfil this job. First devices were magnet tape, floppy disks, ZIP-drives.
The most widespread device now is hard disc. It has huge capacity that allows to store up to 200 Gigabyte of information on a single hard disk. Another memory storage device is CD-ROM. It can contain 700 Megabyte . But nowadays there are DVD devices. DVD looks like CD , but can store 6 times more , up to 4.5 gigabyte.
This is very good , but to carry DVD’s or even a hard disk is not very comfortable. So here we have easy-to- carry Flash cards. They are very small , just like a coin. They are used as a memory storage device in cell-phones, Pocket PCs, players, digital photo and video cameras. And the level of safety on such devices is very high.
