Bot GPT 3.5 A. Circuit switching is a method of communication in which a dedicated communication path or circuit is established between two parties before they can communicate. This path remains open for the duration of the communication and is exclusive to those two parties. On the other hand, packet switching is a method of communication in which data is broken down into packets, which are then sent independently to their destination. Different packets from the same communication can take different paths to reach the destination, and they are reassembled at the destination.
B. The main difference between switching and packet switching techniques is the way in which they handle communication pathways. In circuit switching, a dedicated path is established for the entire duration of the communication, while in packet switching, data is divided into packets that can take different paths to reach the destination. Packet switching allows for more efficient use of network resources as packets can take different routes and avoid network congestion. However, packet switching can introduce delays in communication as packets may arrive out of order and need to be reassembled at the destination. Circuit switching, on the other hand, provides a constant and reliable connection but may be less efficient in terms of resource usage.
