A. Circuit switching is a communication method where a dedicated communication path is established between two communicating parties before any data is transmitted. This path remains open for the entire duration of the communication. Packet switching, on the other hand, breaks data into smaller packets that are independently routed through a network. These packets may take different paths to reach their destination and are reassembled at the end.
B. The main differences between circuit switching and packet switching are:
1. Circuit switching requires the establishment of a dedicated communication path before any data can be transmitted, while packet switching breaks data into packets that are independently routed through the network.
2. In circuit switching, the communication path remains open for the entire duration of the communication, while in packet switching, packets may take different paths to reach their destination and are reassembled at the end.
3. Circuit switching is more suitable for constant bit-rate applications like voice calls, while packet switching is more efficient for bursty data traffic like internet browsing.
4. Circuit switching is less flexible and scalable compared to packet switching, which can handle varying traffic loads more efficiently.
5. Circuit switching provides a guaranteed quality of service, while packet switching does not guarantee delivery or sequence of packets.
