                               COMPUTER LANGUAGES

                     Human needs a common language to communicate with each other. Similarly, computers

                     need a language to communicate with its user, take instructions and to perform operations.
                     The language that is required by a computer is called computer language. This is also
                     known as a programming language.

                     It is a set of words, symbols and codes that the computer can understand. There are a
                     number of programming languages worldwide. Computer languages are classified into
                     two major categories: Low-level language and High-level language.

                     LOW-LEVEL LANGUAGE

                     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.

                     There are two categories of low-level languages:

                     Machine Language

                     Machine language is the only language understood by the computer. It is also known as
                     the first generation language (1GL). Machine language is very difficult for programmers
                     to use because it only consists of two digits, 0 and 1, called binary digits or bits. Where the
                     bit ‘0’ represents the OFF state and the bit ‘1’ represents the ON state.

                                                                                     Algorithm, Flowchart and Mind Maps  89
