The Processing unit in a computer interprets instruction given in programs and carries out
the instructions. Processors are designed to interpret a specified number of instruction codes.
Each instruction code is a string of binary digits. A memory or store is required in a computer to store programs and the data processed by programs. A memory is made up of a large number of cells. with each cell capable of storing of bits. The cells may be organized as a set of addressable words, each word storing a sequence of bits. In one such organization, the time to store or retrieve a word is independent of the address of the word. This organization, called a Random Access Memory (RAM) is used as the main memory of computers. Another organizationl serial access memory.
