Computers have a special language to work with and they are of three main types. A machine language that uses 1's and 0's. Each instruction or piece of information is memorized by a computer by turning it into a different arrangement of 1's and 0's.
Another language is called assembly language. The shortcomings of machine language have been removed in this language. It was developed in 1950.This language uses special code for sum subtraction.
While a third language is a high-level language, it is high-level and complex. It is used to create programs. In high level language many languages like COBOL, PHOTORON, BASIC, PASCAL, C PLUS PLUS have been developed.
A computer stores all information and instructions in the form of memory. Memory is made up of millions of small pieces called bits. There are four types of memory. Internal, Main, RAM, ROM and External Memory.
