What are the three components of telecommunications?

The three components of telecommunications are a transmitter, a transmission medium, and a receiver.

The transmitter is responsible for converting information into signals that can be sent over a distance. This could be anything from a simple microphone converting sound into electrical signals to a complex computer system sending data. The next component, the transmission medium, is the physical or wireless pathway through which the signals travel. This medium can be fiber optic cables, copper wires, or even wireless signals transmitted through the air. Lastly, the receiver takes the signals from the transmission medium and converts them back into a usable format, whether that be audio, video, or data for a computer.

Understanding these components is essential for grasping how communication systems function, from basic telephone systems to complex data networks. The other options provided do not fully encapsulate the necessary components of a telecommunications system.
