Question-1 a) Discus and compare circuit-switching and packet-switching. b) What are the main advantages of a circuit-switched network have over a packet-switched network? c) What advantages does TDM have over FDM in a circuit-switched network?
Circuit-switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated circuit between them. The circuit is then maintained for the duration of the connection. The advantage of circuit-switching is that it provides a guaranteed bandwidth and low latency. The disadvantage is that it is inefficient for applications that do not require a dedicated circuit, such as voice over IP.
Packet-switching is a method of implementing a telecommunications network in which data is divided into small packets that are routed through the network based on their destination. Packet-switching is more efficient than circuit-switching for applications that do not require a dedicated circuit, but it can result in higher latency and lower bandwidth.
