                     COMPUTER LANGUAGES

                 To communicate with  the computers,  we  need some special languages  which  are  called
                 computer languages or  programming languages.  A computer  language  is the  medium
                 by  which  instructions  are  transmitted  to  the  computer  to  perform  a  specific  task.  It  is  a  set
                 of words, symbols and codes that the computer can understand. It is used to write computer

                 programs. A computer program is a set of instructions written in a programming language. The
                 process of writing a program is called programming. People who write the programs are called
                 programmers.  There are a number of programming languages worldwide. Some languages
                 were developed for specific computers, others were developed for specific uses such as scientific
                 or business applications. Computer languages are classified into two major categories:

                           Low-Level Language                                  High-Level Language

                 Low-Level Language (LLL)

                 A low-level language is a programming language that is machine dependent. A program written
