    A computer also follows stepwise instructions to complete any task known as a
                     program. We can define a program as a set of systematic instructions that direct

                     the computer to do specific tasks and get the desired results. Programs are written
                     in a special language known as a programming language. The person who writes
                     these programs is known as a programmer.

                     In  this chapter we will learn  about  Scratch. It is a block-based  programming

                     language.

                               SCRATCH

                     Scratch is a visual programming language used to create computer
                     animation,  games  and  stories.  Visual programming  means  that
                     rather than having to type the code (instructions), we use blocks of

                     code that we put together to create our projects. This makes it easier
                     to get started. It enables us to see the results of our work quickly and
                     even includes graphics and sound to it.

                                                                                                         PURE
                             Scratch was created by Mitchel Resnick at the MIT Media Lab in 2007.        FACT

                               ADVANTAGES OF SCRATCH

                     Scratch is simple, easy to understand and learn. It is used more than many other

                     programming languages for the following reasons:

                        We don’t have to remember or type commands, we can just drag and drop them
                       as we desire.

                        Commands fit together like puzzle pieces, so we get clear visual hints about how

                       to combine them.

                        We can create animations, quizzes and stories.

                       We can create and share our Scratch project online on the Scratch website.
