What are the three methods of transmission?

Explanation:
In transmission, how signals flow between devices and whether two‑way communication can happen at the same time is described by three classic modes: simplex, half‑duplex, and duplex (full duplex). Simplex is one‑way only, like a broadcast signal from a station to viewers with no return path. Half‑duplex allows two‑way communication but not simultaneously—for example, a walkie‑talkie where one person talks at a time. Duplex (full duplex) lets two devices talk and listen at the same time, as in a telephone call. The other options describe different concepts: analog/digital/serial relate to signal types or data formats, unicast/multicast/broadcast are about how data is addressed or delivered, and single-turn/two-turn/three-turn aren’t standard transmission modes.
