Which one of the following statements is FALSE?a)Packet switching lead...
- Circuit switching has 3 phase: connection establishment, Data transfer and tear down, while packet switching has only one phase data transfer based on routing,
- Circuit switching has less variation in packets than packet switching.
- Circuit switching send packet in order, while packet switching send out of order, so reordering needs in packet switching.
- In packet switching no resource reservation needed while circuit switching has resource reservation so packet switching leads to better utilization of resources i.e. bandwidth.
- In circuit switching no packet processing needed at intermediate path routers while in packet switching needed. So, packet switching require more packet processing time than circuit switching.

Which one of the following statements is FALSE?a)Packet switching lead...
False Statement: Packet switching results in less variation in delay than circuit switching.
Explanation:
Packet Switching:
Packet switching is a digital network transmission method that breaks data into small packets, which are then transmitted individually over the network. Each packet contains the necessary information for the network to route it to the destination.
Circuit Switching:
Circuit switching is a traditional method of establishing a dedicated communication path between two devices before the actual data transmission. The path remains reserved for the entire duration of the communication.
Comparison:
Now, let's compare the two statements:
a) Packet switching leads to better utilization of bandwidth resources than circuit switching.
- This statement is true. In packet switching, multiple packets can be transmitted simultaneously, and the available bandwidth is shared among multiple users, leading to efficient utilization.
b) Packet switching results in less variation in delay than circuit switching.
- This statement is false. In packet switching, the delay can vary depending on the network congestion, routing algorithms, and the processing time for each packet. The delay can also be affected by factors like packet loss and retransmissions in case of network errors. In circuit switching, the dedicated path ensures a constant delay throughout the communication.
c) Packet switching requires more per-packet processing than circuit switching.
- This statement is true. In packet switching, each packet needs to be processed individually by network devices such as routers. The processing involves examining the packet headers, making routing decisions, and forwarding the packet to the next hop. In circuit switching, the processing is minimal as the path is established beforehand.
d) Packet switching can lead to reordering unlike in circuit switching.
- This statement is true. In packet switching, packets can take different paths through the network, and they may arrive at the destination out of order. This can happen due to differences in routing or congestion conditions. In circuit switching, the dedicated path ensures that the packets arrive in the correct order.
Conclusion:
The false statement is option 'B' - Packet switching results in less variation in delay than circuit switching. In reality, packet switching can introduce variation in delay due to network conditions, congestion, and packet processing.
