FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A joystick is an input device that can be used for controlling the movement of the cursor or a pointer in a computer device. The pointer/cursor movement is controlled by maneuvering a lever on the joystick. The input device is mostly used for gaming applications and, sometimes, in graphics applications.

Detailed explanation-2: -A joystick, sometimes called a flight stick, is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling.

Detailed explanation-3: -Input and output, or I/O is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.

Detailed explanation-4: -The joystick outputs an analog signal whose voltage varies between 0 and 5V. When you move the joystick along the X axis from one extreme to the other, the X output changes from 0 to 5V, and the same thing happens when you move it along the Y axis.
