What is an advantage of packet-switched technology over circuit-switched technology?
- Packet-switched networks do not require an expensive permanent connection to each endpoint.
- Packet-switched networks can efficiently use multiple routes inside a service provider network.
- Packet-switched networks are less susceptible to jitter than circuit-switched networks are.
- Packet-switched networks usually experience lower latency than circuit-switched networks experience.
Explanation: Packet switching does not require a circuit to be established and is able to route packets across a shared network. The cost of packet switching is lower than that of circuit-switching.
