A. Simplex
-
B. Full-duplex

Explanation
Communication between a keyboard and computer is simplex, meaning data flows in one direction only — from keyboard to computer.
The computer does not send data back to the keyboard during typing.
There are 3 main data transmission modes:
- Simplex: Data flows in one direction only (e.g., keyboard to computer).
- Half-Duplex: Data can flow both ways, but not at the same time (e.g., walkie-talkies).
- Full-Duplex: Data flows both ways simultaneously (e.g., telephone conversations).
