Wireless mice are computer input devices that connect to a computer without the need for a physical cable. They typically use Bluetooth or a USB receiver to communicate with the computer, allowing for greater freedom of movement. This makes them popular for both home and office use, as they reduce clutter and provide a more comfortable user experience. These devices come in various shapes and sizes, catering to different preferences and needs. Many wireless mice feature additional buttons for shortcuts, adjustable sensitivity, and ergonomic designs to enhance usability. They are powered by batteries, which can be rechargeable or replaceable, depending on the model.
