Memory : Computers store information internally as well as externally.

Linked to CPU is an internal memory unit where all the instructions and data are stored. It contains the computer operating instructions or programme. The memory of the computer is of two kinds; RAM and ROM. Random Access Memory (RAM) is the computer's short term working space. During its working life, a computer's RAM may be over batten with new information millions of times. RAM is more like a blank cassette which can be recorded, wiped clean and recorded again. The computer can get to or access any part of the RAM memory 'at random'.

ROM is the Read Only Memory that is, one can read from it but cannot written on it. It is used to store software which will always be needed. ROM software is a permanent part of the machine, unlike the RAM which is forgotten each time the machine is switched off.

The external memory of the computer is the 'floppy' discs and the compact discs (CDs). They need special disc drives to read and write the information on them. CDs can hold an enormous amount of information. Infect, entire encyclopaedias can be stored on one CD.
