What type of communication is described by the term 'simplex'?

Simplex communication refers specifically to one-way communication, where information flows in a single direction from the sender to the receiver, without any feedback or response from the receiver. This type of communication is commonly seen in systems where a sender transmits data without expecting any reply, such as in broadcast radio or television transmissions.

In simplex communication, the sender can send messages continuously, but the receiver has no capability to send messages back, which distinguishes it from two-way communication systems, such as half-duplex and full-duplex systems. Half-duplex allows for both parties to send and receive messages, but not simultaneously, while full-duplex permits simultaneous two-way communication.

This characteristic of simplex communication makes it effective for scenarios where feedback is not necessary, but it limits interactivity and responsiveness. Understanding this fundamental aspect is crucial for grasping broader communication concepts within systems and networks.
