A wireless mouse communicates with a computer through radio frequency (RF) signals or Bluetooth technology.

  1. RF Wireless Mouse: The wireless mouse has a built-in radio transmitter that sends out signals to a receiver (usually a USB dongle) plugged into the computer. The receiver receives the signals and converts them into data that the computer can understand. The computer processes this data and uses it to move the cursor on the screen. The mouse movement and button clicks are sent back to the computer via the same RF signals.
  2. Bluetooth Wireless Mouse: A Bluetooth wireless mouse uses Bluetooth technology to establish a direct connection with a computer or other compatible device. The mouse and the computer are paired by exchanging encrypted identification codes to ensure secure communication. Once paired, the mouse sends movement and click data to the computer through Bluetooth signals. The computer processes the received data and translates it into cursor movement and button clicks on the screen.


In both cases, the wireless mouse requires batteries for power. The signals transmitted by the mouse are relatively low-power, enabling it to operate at a short range (typically a few meters) from the computer.

A wireless mouse communicates with a computer through the use of radio frequency (RF) or Bluetooth technology.


RF wireless mice use a USB receiver that plugs into the computer's USB port. The mouse and receiver operate on the same radio frequency, allowing them to establish a wireless connection. When the mouse is moved or a button is pressed, it sends signals to the receiver, which in turn relays the information to the computer.


Bluetooth wireless mice, on the other hand, use the Bluetooth protocol to establish a direct connection with the computer. They do not require a separate receiver. The mouse and computer need to be paired initially, after which they can communicate wirelessly. When the mouse is moved or a button is pressed, it uses Bluetooth radio waves to transmit the signals directly to the computer's Bluetooth receiver.


In both cases, the computer receives these signals and translates them into mouse movements or button clicks, allowing the user to interact with the computer's graphical user interface.
