Unit-2 Data Entry and Keyboarding Skills
DATA ENTRY & KEYBOARD SKILLS 2
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.
