The computer mouse is one of the most important input devices that helps users interact with a computer. It makes navigation faster and easier, especially when working with graphical interfaces such as Windows or macOS.
What Is a Mouse?
A mouse is a handheld pointing device used to control the movement of a pointer or cursor on the computer screen. It allows users to select, move, and open items without typing commands on the keyboard.
Most modern mice use optical sensors that detect movement by reflecting light on a surface, while older ones used a rubber ball to track motion.
