How does input and output devices communicate?

Answer 1

Input and output devices communicate with a computer through a set of protocols and interfaces that facilitate data transfer. Input devices, like keyboards and mice, send data to the computer's central processing unit (CPU) via input ports, using protocols such as USB or Bluetooth. The CPU processes this data and sends commands or information back to output devices, like monitors or printers, using similar communication protocols. This interaction allows for seamless user input and the display or production of results.
