A keyboard is used as an input device in any computing device. This input device keyboard has been modeled form the typical typewriter keyboard.
In a keyboard the key or buttons are arranged in an order. Over the buttons or keys there are some characters printed, so pressing that particular key will respond to the symbol specified on the key or button. But in some cases pressing the keys or buttons in some combinations in some sequence will perform some operation and if some other keys are pressed then it would result in the operation of the computer and also the key board.
There are different types of keyboards based on the keyboard layouts, wireless types, connection types, dome switch vs. alternatives and alternative to the regular keyboard such as small keyboards, specialty keyboards, virtual keyboards like touch screen keyboards and extra keys keyboards like gaming keyboards and multimedia keyboard.
