What defines a simplex channel in data transmission?

• A. Allows multiple signals to transmit simultaneously
• B. Transmits data in both directions
• C. Transmits data in only one direction
• D. Transmits data with feedback capability

Answer: (C)

A simplex channel in data transmission is defined as one that transmits data in only one direction. This means that signals can travel from a sender to a receiver, but not the other way around. In simplex communication, there is a clear distinction between the transmitter and the receiver; for example, a television broadcast is a practical illustration of a simplex channel, where the signal goes from the station to the viewer with no return communication possible. Understanding this concept is essential, especially when differentiating between other types of communication channels. In contrast, channels that allow for data to be transmitted in both directions demonstrate functionality like half-duplex or full-duplex channels, which are specifically designed for bidirectional communication. Simplex channels have their limitations and specific use cases, which makes recognizing their defining characteristics crucial in the study of data transmission systems.
