Smart Board

                                   A smart board is a large interactive screen used in classrooms. You can
                                   write on it and interact with it using touch or special pens (input). It can
                                   also show videos, presentations, and diagrams (output).

                   i +  IPO CYCLE

                  A computer works on the IPO (Input-Process-Output) cycle. It receives input from the
                  user through input devices, processes it using the CPU and gives back the output using
                  output devices. This cycle is known as IPO cycle.
