    MIND MAPS

                     A Mind Map is a tool that allows us to organise ideas, thoughts or concepts and their relationship
                     in a graphical manner.

                     After the brainstorming  session  is over,  we structure  the ideas  and information,  and their
                     relationship using Mind Maps. In this technique, we pick up the ideas that have common features.
                     These ideas are then grouped under one category, and the different categories are linked to the
                     main topic using lines or arrows. Let us draw a Mind Map for the computer:

                               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.

                                                                                     Algorithm, Flowchart and Mind Maps  71
