                         Students!
                         Have you visited a Railway Reservation Counter?
                         You will be amazed to see the ticket booking clerks who reserve tickets on a computer very fast;
                         while their hands are busy typing the details of passengers, their eyes are set on the reservation
                         form or the screen! They are able to match eyes & hands and work in this manner because of
                         their acumen in typing. Good or Touch typing is a skill that helps to type text or enter data in a
                         computer ‘quickly & accurately’.

                         Touch typing is a method of typing without looking at the keyboard. The fingers of a touch typist
                         know the location of the keys on the keyboard through practice. Touch typing typically involves
                         placing the eight fingers in a horizontal row  on the middle of the keyboard (the home row) and
                         taping the required keys. Touch typing takes place either with both hands or with the use of only
                         one hand.

                         A touch typist possesses a great sense of understanding of when to use which finger and how
                         much  to  move  each  finger  in  order  to  tap  the  required  keys.  To  learn  typing,  it  is  important
                         to  learn  how  to  blindly  place  fingers  on  the  start  position     other  keys  as  the  hands  get
                         frequently raised from the Keyboard to operate the computer Mouse.
                           KEYBOARD

                         Keyboard is the standard input device. A keyboard normally contains 104 to 108 keys. Keys are
                         mainly used to type text and send instructions. Keyboard keys are the buttons that represent
                         alphabets, numeric, alphanumeric and special characters. The keys can also be used in combination
                         with other keys.
                         When a key is pressed, an electrical signal is generated. These electric signals are transmitted in a
                         coded form (ASCII form) to the computer describing the character which corresponds to that key.

                         Types of Keys

                         Following are the different types of keys:
                           Alphabet Keys: There are 26 Alphabet keys (A– ) on a keyboard that help to type letters. They
                            are not arranged in alphabetical sequence on the keyboard.

                            Number Keys: There are ten (1 )  umeric keys ( – ) on a keyboard. They help to type numbers.
                            They lie at two different places on a standard keyboard i.e., above alphabet keys and towards
                            the right side of a keyboard.  umeric keys placed on the right side of the keyboard are referred
                            to as  umeric Keypad.
