What is the difference between a mouse and a tackerball?

A mouse is a handheld device used to control a computer's cursor, typically featuring buttons and a scroll wheel, allowing for precise navigation and interaction with graphical user interfaces. A trackball, on the other hand, is a stationary input device that consists of a ball encased in a socket, which users rotate to move the cursor on the screen. While a mouse requires movement across a surface, a trackball remains in one place, making it beneficial for limited desk space or for users with certain mobility issues.
