Which feature distinguishes packet switching from circuit switching?

Packet switching is distinguished by its ability to allow simultaneous usage by multiple users without a dedicated line. In a packet-switched network, data is broken down into packets which are transmitted independently over the network. Each packet may take different paths to reach the destination, where they are reassembled. This method enhances network efficiency and resource utilization, as multiple communications can share the same network pathways, leading to more flexible and scalable communication.

The other concepts are more aligned with circuit switching, where a dedicated circuit is established for the entire duration of a communication session, ensuring exclusive use of the resources for that connection. This rigidity contrasts with packet switching’s dynamic approach, encouraging higher efficiency and adaptability in managing network traffic.
