Question

Which of the following statements are false?
a. Datagram is faster than virtual circuits if the number of packets transmitted is small.
b. Datagram is faster than virtual circuits if the number of packets transmitted is large.
c. In circuit switching, a dedicated communication path is established between two end stations.
d. Datagram does not require connection establishment phase.

Answer 1

Answer:

B

Explanation:

Datagram is faster than virtual circuits if the number of packets transmitted is large. FALSE

For the situation, if the quantity of packets transmitted is enormous then Datagram is quicker than virtual circuits.

For the time throughout which the recently arrangement Virtual Circuits will be utilized by a data transfer session, there will a booking of resources like buffer, bandwidth, and so on because Virtual circuits are connection-oriented.

On the other hand,

Database is a connection service and has no committed path for a connection session. There is no requirement for reservation of resources.

Answer 2

Answer:

The false statement given above in the question is - b) Datagram is faster than virtual circuits if the number of packets transmitted is large.

A network dependent on packet switching mode that is used as a basic transfer unit is called datagram.

It has two sections - payload and header.

Datagram uses Asynchronous mode of data transfer and provides services that are connection less. Hence the packets are sent randomly without being sorted.

Whereas Virtual circuit gives services that are connection oriented.
