MEMORY OR STOREGE UNIT

The part of a digital computer which stores information is called storage or memory. The computer’s memory stores the numbers to be operated on; it stores intermediate results and it stores the final results. The instruction themselves are also stored in the computer’s memory.

There are two important factors about the memory unit: an access time and a capacity. The time required to transmit one computer word out of the memory to where it will be used is called the memory access time; it usually amounts to a few millionths of a second or less in modern fast computers. The capacity of a computer is the quantity of data that its memory unit can hold.

There are many ways of memorizing information in memory cells of a digital computer. External memory or storage units may use magnetic tapes, magnetic drums, magnetic disks and floppy disks. Information that is stored inside a computer is stored in registers. Usually the registers are of three types:

1. General- Purpose Registers are sixteen registers, each being able to contain one word. There registers are used for storing the integer operands taking part in binary arithmetic operations.

2. Floating-Point Registers are four registers, each being able to contain a double-word. These registers hold the operands taking part in arithmetic operations on floating-point numbers.

3. Control Registers form a group of registers differing from one model to another.
