Explanation / Answer

11. Frequency division multiplexing

FDM is the most noisy and simplest of all multiplexing techniques. Time division are less noisy but need more robust approach to implement and dense wavelength puts data into opitc fibres and data travel speed is very high but at the same time that also comes with a lot of implementation challenges

12. data and voice both

A B-Channel ISDN carries both data and voices.

13. Gaurdbands

It is the role of a gaurdband that helps to stop interference between two networks. It often leads to some amount of data as all the interfearing signals are blocked but at the same time, helps to stop interferance

14. both synchronous and statistical

TDM can be both synchronous and statistical. In synchronous a bandwidth is divided into numerous users, and connection is in use always. In statistical TDM, bandwidth is provided only to those connection that are using the network, hence leads to good unilization of resources

15. bits

In computer networks, while sending frames, a set of distinctive bits or set of bits are send along with the data frames. These bits helps to identify the data , extract and decode and also used in the process of retransmission

16. 6000kbps

For a usual TDM, for 10 computers, if 1 computer needs 1500kpbs network, 10 computers will require 1500*10

=15000Kbps network.

But since its a statistical TDM, and 40% of the computer are not transmitting, it leads to requirement of only 40% of the total capacity.

Hence 40% of 1500 = 6000Kbps

Statistical TDM reserves spaces for only few set of networks that require data transmission. Thus full capacity is not required at a time. Only a fraction of total capacty is required
