- 3. INTRODUCTION Input/Output devices arethe pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices.
- 4. INPUT DEVICE Input Deviceis a piece of equipment/hardware which helps us enter data into a computer is called an input device. Input device are the devices that are used to send signals to the computer for performing tasks. The receiver at the end is the CPU (Central Processing Unit), which works to send signals to the output devices. For example : keyboard, mouse, joystick, microphone etc.
- 5. KEYBOARD •A simple devicecomprising keys and each key denotes either an alphabet, number or number commands which can be given to a computer for various actions to be performed •It has a modified version of typewriter keys •The keyboard is an essential input device and computer and laptops both use keyboards to give commands to the computer
