A wireless keyboard works by using radiofrequency (RF) or Bluetooth technology to communicate with a computer or another device. Here's how it works:
Keystrokes: When you press a key on the wireless keyboard, it registers the keystroke by completing an electrical circuit.
Data Encoding: The keyboard's internal circuitry encodes the keypress into a digital signal.
Wireless Transmission: This digital signal is then sent wirelessly to a receiver, which is either built into the computer or a separate USB dongle that you plug into a USB port.
Receiver: The receiver receives the signal and decodes it back into the corresponding keypress, which is then sent to the computer.
Computer Input: The computer processes the keypress as if it had come from a wired keyboard, allowing you to input text or control the computer wirelessly.
The most common wireless technologies for keyboards are RF and Bluetooth, both of which provide reliable and secure connections.
