• A. Packet switching leads to better utilization of bandwidth resources than circuit switching
• B. Packet switching results in less variation in delay than circuit switching
• C. Packet switching requires more per-packet processing than circuit switching
• D. Packet switching can lead to reordering unlike in circuit switching

Comments

@set2018 can you please explain a bit more about datagram and virtual circuit approach?

set2018 The virtual circuit approach in Packet Switching is not used in the Internet.

It is majorly used in X.25 and Asynchronous Transfer mode.

 

So, by default consider the connectionless version of Packet Switching (Datagram approach)

Answer 1

B.

Variation in delay depends on router.

There is no guarantee that if we employ packet switching over circuit switching then we will tend to receive fruitful results over packet transmission and less delay.

It is inherently a false statement
