Personal Digital Assistant (PDA)
                  Personal Digital Assistant (PDA) is a handheld computer that has a

                  touchscreen and allows us to organize our daily routine works like schedules,
                  calendars and address book information. It also has a pen-like stylus which
                  allows us to give input. It can also accept handwritten input directly from the
                  touchscreen.

                            DEVICES OF A COMPUTER


                  As you know, a computer works in three steps: input  process  output.

                     Input is any data or instruction entered into a computer. The input devices help us enter data
                    and give commands to the computer.

                     Process refers to the work done by the computer with the help of the processor.
                     Output refers to the result that has been processed by the CPU.

                  We use different devices for each step. Let us learn about these devices in detail.


                  INPUT DEVICES

                  We have already read about some of the commonly used input devices in earlier classes. Let us
                  now learn about a few more here.
