Communication between a computer and a keyboard involves ______________…

In simplex transmission, data flows in a single direction. For a keyboard, data is sent from the keyboard to the computer only, with no return data. This matches simplex transmission. Other options are incorrect because: Automatic transmission implies no user input, which is not the case here. Half-duplex allows two-way communication but not at the same time, but the keyboard does not send data back. Full-duplex allows simultaneous two-way communication, which is not needed for keyboard input.
