                 In the previous class, we have learnt that a computer can perform a variety of tasks. It
                 works according to the commands or instructions given by us. Most of the machines
                 that we use in our daily life also work according to the commands given by us.


                  i +  WORKING OF MACHINES
                 Let’s see how these machines work.
