Which term describes sending and receiving data at the same time?

• A. Simplex
• B. Half duplex
• C. Full duplex
• D. Polling

Answer: (C)

Full duplex describes sending and receiving data at the same time. In this mode, there are separate paths or signaling that allow simultaneous two-way communication, like a telephone call where both people can talk and listen concurrently. In networks, full duplex means a link can transmit and receive simultaneously, improving throughput and avoiding collisions. The other terms describe different patterns: simplex is one-way only, half duplex allows two-way communication but not at the same time, and polling is a method for controlling which device gets to send, not a description of simultaneous data flow.
