How does multiplexing enhance network efficiency?

• A. By increasing data transfer speeds
• B. By allowing only one signal through a channel
• C. By allowing multiple signals to share a single communication channel
• D. By reducing the number of necessary connections

Answer: (C)

Multiplexing enhances network efficiency by allowing multiple signals to share a single communication channel. This process maximizes the use of the available bandwidth by breaking it into smaller sub-channels, each capable of carrying separate data streams simultaneously. By utilizing multiplexing, a network can transmit more data over the same medium without needing additional physical infrastructure, which makes it a cost-effective solution. This capability is particularly important in environments where the demand for bandwidth is high, as it reduces congestion and improves overall data transmission rates without requiring extra lines or connections. In contrast to the other options, which either suggest a limitation (like allowing only one signal) or do not directly relate to how multiplexing operates, the concept of sharing a channel with multiple signals is foundational to understanding the efficiency gains multiplexing brings to network operations.
