Today, we are living in the age of digital technology where electronic gadgets like computers, laptops, mobile
phones, etc. have become the part of our day to day life. We use these devices to do almost every type of job
ranging from documentation to sending e-mails, messages and maintaining all type of records electronically.
To work with these devices, we input our data or commands with the help of a popular input device called
keyboard. This device has many keys or buttons on it with different characters, numbers and special symbols
printed on them. We press these keys to input the specifi c characters printed on them. To get our work done
quickly by the computer, we need to press these keys quickly and accurately. The process of inputing or writing
text by pressing the keys on the keyboard is called typing. So, we can say that typing plays a very vital role in
the effi cient use of computer system.

at our keyboard.
