IMPORTANCE OF COMPUTER LANGUAGE


          Computers are basically machines that have to be told what to do. Unfortunately, computers don’t understand human language-they have their own languages. The term computer language includes a wide variety of languages used to communicate with computers.
           Computer languages can be of different types. There are high level languages, assembly languages, machine languages, and fourth generation languages. High level languages such as BASIC, COBOL, and FORTRAN are also known as programming languages.

             Each language has its strength and weaknesses. Some are good for processing numerical data, others are good for creating readable programmes.
             Machine language consist of only numbers, while assembly languages allow a programme to substitute names for numbers.
             Fourth generation languages are the most sophisticated, and are also the closest to human language.
