Answer 1

Answer:

the answer is option number B

Answer 2

The statement regarding packet switching which is not true is :-

c. The packet transfer delay between a pair of nodes is more or less constant.

The method in which data is transferred to a network in the forms of packet is called packet switching. The data is broken into several small pieces to ensure efficiency in data transfer rate.

These small pieces are called packets. As it is a store and forward network, delay occurs in packet switching , thus it is not constant overall.
