How does packet-switched networking differ from circuit-switched networking?

Packet-switched networking fundamentally differs from circuit-switched networking in how it handles data transmission over a network. In packet-switched networks, data is broken down into smaller, manageable units known as packets. Each of these packets can be transmitted independently of one another, taking various routes across the network to reach the destination. This approach allows for more efficient use of network resources, as multiple packets from different sources can share the same pathways without the need for a dedicated connection.

In contrast, circuit-switched networking establishes a dedicated communication path or circuit between two endpoints for the duration of the call or session. This method can lead to resource inefficiencies since the dedicated path is reserved even if no data is actively being transmitted.

The ability to send packets independently means that packet-switched networks can better accommodate a range of data types and network conditions. Additionally, this flexibility enables dynamic routing of packets, which can be beneficial for managing network traffic and improving performance.
