    Communications 1 min read

    Refers to transmission in only one direction. Note the difference between simplex and half-duplex. Half-duplex refers to two-way communications where only one party can transmit at a time. Simplex refers to one-way communications where one party is the transmitter and the other is the receiver. An example of simplex communications is a simple radio, which you can receive data from stations but can’t transmit data.
