Half duplex communication means that a system may transmit and receive signals, but not at the same time. It has to switch over from transmit to receive, and vice-versa.
Think of an analogy of a walkie-talkie; when you press the transmit button you cannot hear or receive a message until you release the transmit button.

Rahmat khairkhwa Half-duplex Ethernet operates in a shared collision domain. Half-duplex Ethernet has lower effective throughput.
half duples
CAN is half-duplex. One differential pair means one message at a time.
TCP is usually used as full duplex, but in some case, half duplex can also be used in TCP.
simplex half-duplex duplex
A simple duplex is a channel through which data is transmitted and it can either be half or full duplex. Half duplex means that data can be sent or received but not at the same time while full duplex means that this can happen simultaneously.
Full duplex has the highest throughput concering communication.
Half duplex means it communicates in one direction only. It either listens all the time, or it talks all the time. A half duplex satellite would be pretty useless. In reference to services like DirectTV, the user sees the satellite as half duplex, but for the satellite owner, it is full duplex communication to their ground station.
What is software
half duplex modem is each station can transmit and receive but not at the same time. full duplex modem is both stations can transmit and receive simultaneously.
