Telecommunications[]
A data link (also called a communications link) is the means of connecting one location to another for the purpose of transmitting and receiving digital information.
Overview[]
It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver [two data terminal equipments (DTEs)] and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink.
There are at least three types of basic data-link configurations that can be conceived of and used:
- Simplex communications — most commonly meaning all communications in one direction only.
- Half-duplex communications — meaning communications in both directions, but not both ways simultaneously.
- Duplex communications — communications in both directions simultaneously.
