A wireless mouse is a computer input device that allows users to control the cursor on their screen without the need for a physical connection to the computer. It typically uses Bluetooth or a USB receiver to communicate with the computer, providing greater freedom of movement and reducing cable clutter. Wireless mice come in various shapes and sizes, catering to different user preferences and ergonomic needs. They often feature buttons for additional functions, such as scrolling or shortcuts, and are powered by batteries or rechargeable systems. This convenience makes them popular for both home and office use.
