Question

There are two methods of enforcing the rule that only one device can transmit. In the centralized method, one station is in control and can either transmit or allow a specified other station to transmit. In the decentralized method, the stations jointly cooperate in taking turns.
What do you see as the advantages and disadvantages of the two methods?

Answer 1

Answer:

In centralized method, the authorized sender is known, but the transmission line is dominated by the control station, while in decentralized method, one station can not dominate the line but collision on the transmission line may occur.

Explanation:

Centralized method of communication requires for a control station to manage the activities if other stations in the network. It assigns turns to one known station at a time, for transmission.

Decentralized method allows stations in a network to negotiate and take turns in transmitting data. When a station is done with the transmission line, another station on the queue immediately claims the line.
