Question

__________ multiplexing is a good choice for connecting a number of lower-speed devices that do not transmit data on a continuous basis to a Synchronous time division Statistical time division Frequency division Time division ____________ division multiplexing is the assignment overlapping frequency ranges to each user of a medium. Time Synchronous time Frequency Code division In statistical time division multiplexing, how is it possible to identify which data belongs to which station? By the station number Round robin fashion By address of each station attached to the transmitted data Data can be transmitted from the sender to the receiver and from the receiver to the sender in only one direction at a time in a(n) ________ connection. Half duplex Full duplex Simplex echo __________ multiplexing allows multiple users to share a common set of frequencies by assigning unique digital codes to each user. Dense wavelength division Code division Frequency division Statistical time division If time division multiplexing is used for multiplexing 3 data streams (A at 10000 bps, B at 15000 bps, and C at 5000 bps). what would be the connect frame sequence structure? C-C-C-B-A-A

Explanation / Answer

Find answers below.

22. Statistical time division

Note:

23. Frequency

Note: examples are radio spectrum, optical fiber.

24. by address of each station attached to the transmitted data.

Reason:

In statistical multiplexing packets or frames contains destination address information (channel or stream data id).

25. Half Duplex

Note: Half duplex is two-way communication but one direction at a time, for example walkie-talkie, both users can talk but one at a time.

26. Code division

Note: It assigns unique digital code to each user.
