Question: Trackball is a………..

Answer:

A trackball is a pointing device that is used to control the movement of a cursor or pointer on a computer screen. It is similar to a mouse but operates differently in terms of its design and functionality.

A trackball consists of a ball housed in a socket, which can be rotated in any direction by the user's fingers or palm. The movement of the ball translates into corresponding cursor movement on the screen. The trackball is typically surrounded by buttons that can be clicked to perform various actions, such as selecting objects or activating functions.

Trackballs are available in various sizes and configurations. Some trackballs are integrated into keyboards, while others are standalone devices that can be connected to a computer via USB or wireless connections
