Multiplexing and Switching

1. What is meant by bandwidth utilization?

Ans: Bandwidth utilization refers to the wise use of the available bandwidth in order to achieve the utmost efficiency, privacy and anti-jamming. Bandwidth can be used optimally using two techniques, namely, multiplexing and spreading. Multiplexing allows sharing the available bandwidth of a communication link among a number of communicating stations, thus achieving efficiency. On the other hand, spreading allows expanding the bandwidth of link for achieving privacy and anti-jamming.

2. What is multiplexing? In what situations, it can be used?

Ans: Multiplexing is a technique used for transmitting several signals simultaneously over a single communication link. An analogy ...
