Best Answer

Simplex communication is one way only. One host transmits, one receives, but they can't do both. A radio is an example. You can receive a signal but you can't send a reply. Half-duplex is two-way, but you can't transmit and receive at the same time. A walkie-talkie ir CB radio is an example. Full duplex is two-way, and you can send and receive at the same time. A telephone is full duplex. You are sending (talking) and receiving (listening and hearing) at the same time.

What Direction of Data Flow?

The direction of the data flow can be described as: 1. Simplex 2. Half duplex 3. Full duplex 1. Simplex:- In Simplex data flows in only one direction on the data communication line (medium). Examples are radio and television broadcasts. They go from the TV station to your home television 2. Half duplex:-In Half-Duplex data flows in both directions but only one direction at a time on the data communication line. For example, a conversation on walkie-talkies is a half-duplex data flow 3. Full-Duplex: In full duplex data flows in both directions simultaneously. Modems are configured to flow data in both directions


Is an oil pipeline simplex half-duplex or full-duplex and why?

An oil pipeline would be classified as SIMPLEX, because the oil flows in only one direction. Theoretically, I suppose it also could be half-duplex (flows in only one direction at a time, but can change direction). However, it would be very impractical to switch the direction of flow (but not impossible).
