or cord. Wireless mouse that use other radio
frequencies (RF) come with their own transceiver that
plugs into the USB port of the computer.
• The mouse uses some manner of wireless technology,
like Bluetooth, RF, or infrared radio waves. Usually, a
USB receiver is plugged into the computer and receives
signals from the wireless mouse.
