                   i +  COMPUTER LANGUAGES

                  Humans  need  a  common  language  to  communicate  with  each  other.  Similarly,  computers
                  need a language to communicate with its user, take instructions, and perform operations. The
                  language that is required by a computer is called computer language. This is also known as a
                  programming language.
                  A computer language is a 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.
                  A computer program is a set of instructions written in a programming language. There are a
                  number of programming languages worldwide.

                  Computer languages are classified into two major categories: Low-level language and High-level
                  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.

                  Computer languages are classified into two major categories:

                                                   Computer Languages




                          Low-Level Language                                    High-Level Language





                       Machine           Assembly        Third Generation  Fourth-Generation             Natural
                   Language (1GL)     Language (2GL)     Language (3GL)        Language (4GL)       Language (5GL)

                  Low-Level Language (LLL)

                  Low-level  language is a programming  language  that  deals with  the  computer’s  hardware
                  components. It is machine-dependent. A set of low-level language instructions written for a
                  particular type of computer will not work on a computer with a different design. These languages
                  are also known as computers’ native languages.
