Central Processing Unit

The central processing unit (CPU) is the brain of the computer. It:

interprets instructions to the computer (control unit),performs the arithmetic and logical processing (ALU)

Memory

Memory, also called Random Access Memory or RAM stores:

instructions waiting to be executeddata needed by those instructionsresults of processed data

Any information stored in RAM is lost when the computer is turned off.


25/33

Memory Data in memory is stored as binary digits (BITS) e.g.

011100101010

1 BYTE = 8 bits

1 byte usually stores 1 text character.
