A pointing device is an input tool used to interact with a computer's graphical user interface. Common examples include a mouse, trackpad, and stylus. These devices allow users to move a cursor on the screen, select items, and execute commands by clicking or tapping. Pointing devices translate physical movement into digital signals, enabling precise control over computer functions. They are essential for tasks such as navigating websites, editing documents, and playing games. The design and functionality of pointing devices can vary, but their primary purpose remains the same: to facilitate user interaction with digital environments.
