Computer’s Memory

January 17, 2008 on 12:48 pm | In Computers |

The computer’s memory has a cell in which numbers can be placed. Each cell has the address for storing a single number. The computer can be instructed to put the number into the cell. The information stored in memory can represent anything. The letters, numbers and the instructions can be placed into the memory of the computer.  Because the Central Processing Unit does not differentiate between different types of information, so it depends upon the software to give significance to the memory. Most of the computers memory cell is set for storing binary numbers in the groups of eight bits (byte). Each byte can represent 256 different numbers from 0-255. For storing more numbers several bytes are used. The computer’s memory can store any kind of information in memory as long as it can be represented in the numerical form. A special set of memory cells known as registers in the Central Processing Unit, the registers can be read and written to more rapidly than the main memory area. Registers are used for the most frequently needed data items to avoid having to access to the main memory whenever data is needed. The computer’s main memory comes in two verities such as random access memory and read only memory.
