                     COMPUTER LANGUAGES

                 A computer cannot understand  any instruction that we may give in English  or in any other

                 language. To communicate with the computers, specialised languages are needed, 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 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.
