                  You use a pencil to write on paper. In the same way, you need a keyboard to write

                  on the computer screen.






















                  A keyboard has small buttons on it called keys. You can type text on the computer
                  by pressing these keys.


                      KEYS ON THE KEYBOARD

                  A keyboard consists of 101 to 104 keys. These keys are divided into three categories:

                  1.    Alphabet keys                 (A–Z or a–z)

                  2.    Number keys                   (1, 2, 3, ..., 9  and 0 [zero])
                  3.    Special keys                    (Enter key, Spacebar key, Backspace key, etc.)
