INPUT DEVICE
An input device can be defined as an electromechanical device that allows the user to feed data and instructions into the computer for analysis, storage, and to give the commands to the computer. Data and instructions are entered into the computer’s main memory through an input device. Input device captures data and translates it into a form that can be broadly classified into the following categories:
Key board
A keyboard is the most common input device. Using a keyboard, the user can type the text and execute commands. Keyboard is designed to resemble a regular typewriter with a few additional keys. Data is entered into the computer by simply pressing various keys.
The layout of a keyboard comes in various styles but QWERTY is the most common layout. The layout of the keyboard has changed very little ever since it was introduced. In fact, the most common change in its technology has simply been the natural evolution of adding more keys that provide additional functionality. The number of keys on a keyboard varies from 82 keys to 108 keys. Portable computers such as laptops quite often have custom keyboards that have slightly different key arrangements from a standard keyboard
