What does "highway" refer to in telecommunications?

• A. A single-channel radio station
• B. A series of fiber optic cables
• C. A digital serial-coded bit stream with time slots for calls
• D. A traditional road for delivery vehicles

Answer: (C)

In telecommunications, the term "highway" specifically refers to a digital serial-coded bit stream that includes time slots for calls. This concept is fundamental to the way information is transmitted across digital communication networks. Essentially, the highway acts as a pathway that allows multiple calls or data streams to be transmitted simultaneously over the same physical medium. This is achieved through time-division multiplexing, where time slots are allocated to different data streams, enabling efficient use of bandwidth. As a result, multiple conversations can occur at once without interference, making it a vital aspect of modern telecommunication systems. The other choices do not align with the established definition in telecommunications. For instance, a single-channel radio station does not convey the simultaneous multi-channel capability implied by the term "highway." Similarly, while fiber optic cables are essential infrastructure for high-bandwidth communication, they represent the physical medium rather than the multiplexed digital data streams themselves. A traditional road for delivery vehicles is unrelated to telecommunications concepts and serves a completely different purpose in transportation logistics, making it irrelevant in this context.
