Data Transmission

Posted on

All information must be transmitted from one place to another in order for it to be received across the globe.


There are three types of data transmission:

Simplex – One way transmission only. A one way system. For example, a radio.

Half duplex  A two-way transmission, but it only allows one way at a time. For example a walkie-talkie.

Duplex (or full-duplex)- Two way transmission, that allows information to be transmitted at the same time. For example, a telephone.
