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

OPTION (B)Datagram is faster than virtual circuits if the number of packets transmitted is large.

Answer 2

Answer:

From the above given option, the false statement is :

option 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.

Data without header has a minimum size of 20 bytes.

So, excluding the length of the UDP header which is of 20 bytes, it leaves the length of 65,507 bytes approximately.

Datagram uses Asynchronous mode of data transfer
