UNDERSTANDING PROGRAMS


                 A computer understands step-by-step instructions written only in a computer language, called
                 as program. The computer reads the program we write and follows our instructions.

                 Let's write a program to make a square.





                      Move 2 steps right.

                      Move 2 steps up.

                      Move 2 steps left.

                      Move 2 steps down.



                                                                                         Start

                 Similarly, we can write a program to make a rectangle.



                      Move 2 steps right.


                      Move 1 step up.
                      Move 2 steps left.

                      Move 1 step down.                                                  Start

                            The process of completing one step and going onto the other is known as stepwise thinking.

                            Decision making is a process of arriving at a conclusion by making a choice.

                            The act of repeating an action again and again is called looping.

                            A program is a step-by-step instructions for a computer to perform a task.




                        Choose the correct option.


                        1.  What is the process of completing one step and going onto the other known as?

                                 a.  Stepwise thinking                         b.  Problem solving

                                 c.  Looping                                   d.  Packing
