An information processing system, such as a computer or information appliance, requires input devices to provide data and control signals. Keyboards, mice, scanners, cameras, joysticks, and microphones are a few examples of input devices.
An input device known as a joystick, sometimes known as a flying stick, consists of a stick that pivots on a base and communicates its angle or direction to the device it is controlling. The primary control system in the cockpit of many commercial and military aircraft is a joystick, commonly referred to as the control column, either as the center stick (or side-stick). It features a number of switches that the pilot and first officer of the flight can use to control the motions of the aircraft.

The term "microphone" refers to a transducer that transforms sound into an electrical signal. Telephones, hearing aids, public address systems for concert halls and public gatherings, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television transmission are just a few of the uses for microphones. Additionally, they are utilized in computers for knock sensors, ultrasonic sensors, speech recognition, VoIP, and other functions.

For computer editing and display, a scanner is a device that extracts images from photographic prints, posters, magazine pages, and other sources.
Scanners typically connect to computers and come with scanning software that allows you to resize and perform other operations.
Types of Scanners

A pointing device allows a user to input spatial data to a computer.
It is commonly used as a simple and intuitive way to select items on a computer screen either by moving a mouse pointer, or, in the case of a touch screen, by physically touching the item on screen. Common pointing devices include mice, touchpads, and touch screens.

A keyboard is a human interface device which is represented as a layout of buttons.
Each button, or key, can be used to either input an alphanumeric character to a computer, or to call upon a particular function of the computer. It acts as the main text entry interface for most users.
