A wireless mouse is a computer pointing device that uses wireless technology, such as Bluetooth or radio frequency, to connect to a computer or other device. It typically features a scroll wheel and left and right buttons for clicking, as well as additional buttons for customizable functions. Wireless mice offer greater freedom of movement and eliminate the need for a physical cord connection to the device they are being used with. They are powered by batteries or rechargeable cells and often come with a USB receiver that plugs into the computer for the wireless connection to work. Wireless mice are popular for their convenience and ease of use in various computing environments.
