Which signaling method is described as simultaneous or sequential transmission or both, and reception of multiple signals on a signaling line circuit?

• A. Switching
• B. Modulation
• C. Multiplexing
• D. Broadcasting

Answer: (C)

Multiplexing is the signaling method that lets several signals share a single signaling line by combining them for transmission and then separating them at the receiver. It can transmit signals simultaneously using different channels on the same line (for example, frequency-division multiplexing) or in sequence where signals take turns on the line (time-division multiplexing). At the receiving end, a demultiplexer splits the combined signal back into its individual components. This approach makes efficient use of a single circuit by handling multiple data streams rather than dedicating separate lines to each one. Switching, on the other hand, is about choosing a path through a network rather than sharing a single line for multiple signals. Modulation changes a carrier signal to convey information, typically for one signal at a time, though carriers can be multiplexed, the concept of multiplexing specifically describes combining and then separating multiple signals on one line. Broadcasting sends the same signal to many receivers, not multiple distinct signals on the same line.
