Correct answer: B. Half-duplex
- A. Simplex
- B. Half-duplex
- C. Full-duplex
- D. All of these
Explanation
In communication between a CPU and a printer, data flows in one direction at a time. The CPU sends the data (print job) to the printer, and then waits for the printer to acknowledge receipt and complete the printing task. The printer doesn't send data back to the CPU until the communication cycle is complete. This type of communication is characteristic of half-duplex mode.
