                    State
                    whether the following statements are true or false.
                    1.    Flowchart is a set of instructions that can be followed to perform a specific
                       task, workflow or process.                                                     __________
                    2.   An algorithm is a set of steps in a sequential manner to solve a problem or
                      to complete a task.                                                              __________
                    3.   Flowcharts are used in analysing, designing, documenting or managing a

                       process or program in various fields.                                           __________




                 We have already learnt that computers follow certain steps to perform any task and when we perform
                 a sequence of steps to solve any problem, it is called an algorithm. Let us now learn about computer

                 languages used to develop programs.

                        COMPUTER LANGUAGES


                 To communicate with the computers, we need some special languages which are called computer

                 languages or programming languages. A computer language is the 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. It is used to write computer programs. A computer program is
                 a set of instructions written in a programming language. The process of writing a program is called
                 programming. People who write the programs are called programmers.
