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.



              A.  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
