Which of the following statements is incorrect?
- a)Circuit switching takes place at physical layer and a circuit switched network is made of a set of switches connected by physical links, in which each link is divided into n channels.
- b)In packet switching, there is no reserved bandwidths on the links and there is no scheduled processing time for each packet.
- c)In a datagram network, each packet is dependent of the other packets.
- d)The efficiency of a datagram network is better than that of a circuit-switched network.
Correct answer is option 'C'. Can you explain this answer?

In a datagram network, each packet is treated independently of all others. Even if a packet is a part of the multi-packet transmission, the network treats it as though it existed alone.
The efficiency of a datagram network is better than that of a circuit-switched network; resources are allocated only when there are packets to be transferred.
Hence, the correct option is (C).

Understanding the Incorrect Statement
The correct answer is option 'C', which states: "In a datagram network, each packet is dependent on the other packets." This statement is incorrect. Here's why:
Characteristics of Datagram Networks
- Independence of Packets: In a datagram network, each packet is treated as an independent entity. This means that packets can take different paths to reach the destination, and they do not rely on each other for routing or delivery.
- No Order Guarantee: Since packets are independent, there is no guarantee of the order in which they will arrive. For example, packet A may arrive before packet B, even if B was sent first.
Comparison with Circuit Switching
- Circuit Switching: In circuit-switched networks, a dedicated path is established for the duration of the communication session. This means that packets sent over this path are dependent on the circuit’s established order and availability.
- Packet Switching: In contrast, packet switching allows for more flexible and efficient use of network resources, as packets can be routed based on current network conditions without dependencies.
Conclusion
The key takeaway is that in a datagram network, packets are independent and can arrive in any order, making option 'C' incorrect. Understanding this concept is crucial for analyzing different network architectures and their efficiencies.
