Question 1

Compare circuit- and packet-switched networks.

Accepted Answer

Old phone systems use a technology called circuit switching. A "circuit" is a dedicated connection between two entities. In a circuit-switched network, a call results in a circuit being opened, dedicating a specific amount of capacity between the communicating parties. The users are using that "circuit" regardless of whether they are talking or not.
Internet networks are packet-switched networks and these can be more efficient. Since conversations can be sliced up into packets, they can be squeezed into smaller spaces. If there are pauses in a conversation or someone's on hold, applications don't hold up the network. And that creates an opportunity to use the network's available capacity for other users. The trade off is one that swaps circuit-switching quality of service (QoS) with packet switching's efficiency and cost savings.
