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. There are two categories of low-level languages:


                                                                            Algorithm, Flowchart and Mind Maps  107
