Simplex, half-duplex and full-duplex

Simplex, half-duplex and full-duplex

Which way the data flows, and when.

Transcript

Simplex mode sends data in one direction only, from the sender to the receiver.

For example, a computer sending a document to a printer.

Half duplex sends data in both directions, but not at the same time.

For example, a walkie talkie: you speak, then you listen.

Full duplex sends data in both directions at the same time.

For example, a broadband internet connection.

So: one direction only, both directions taking turns, or both directions at once.

Simplex, half duplex, full duplex. It is all about direction, and timing.
