Give a brief summary of the key differences between circuit- and packet-switched networks.

What is the difference between a circuit-switched network and a packet-switched network?What does TDM do better than FDM in a circuit-switched network?

Why are circuit-switched networks better than packet-switched ones? In a circuit-switched network, how does TDM improve over FDM?

In a nutshell, explain what makes circuit-switched networks different from packet-switched ones.

Explain the datagram approach and virtual circuit approach to transfer the packets from source to destination at network layer. Which is better and why?

In this paragraph, two advantages and disadvantages of circuit switch networks and packet switch networks should be listed:

What is the significance of latency in the context of wide area networks?

There are three layers in the hierarchical design of Ethernet networks.With the aid of a diagram, briefly explain these layers?

What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in a circuit-switched network?

Unlike datagram and virtual-circuit networks, circuit-switched networks do not require a routing or switching table to establish the output port from which information relevant to a destination can be conveyed. Please explain what is causing this disparity.
