A wireless mouse is a computer input device that connects to a computer without the use of cables. It typically uses Bluetooth or a USB receiver to communicate with the computer, allowing for greater freedom of movement. Wireless mice are powered by batteries, which can be rechargeable or disposable, depending on the model. These devices come in various shapes and sizes, catering to different user preferences and ergonomic needs. Many wireless mice also feature additional buttons for enhanced functionality, such as scrolling or gaming. They are popular for both home and office use due to their convenience and portability.
