Answer:C
A single channel is shared by multiple signals by ____________
A. analog modulation B. digital modulation C. multiplexing D. phase modulation
Explanation: In communication and computer networks, the main goal is to share a scarce resource. This is done by multiplexing, where multiple analog or digital signals are combined into one signal over a shared medium. The multiple kinds of signals are designated by the transport layer which is the layer present on a higher level than the physical layer.
