$50$ What is one difference between the client$-$server and peer$-$to$-$peer network models?

A peer$-$to$-$peer network transfers data faster than a transfer using a client$-$server network.

A data transfer that uses a device serving in a client role requires that a dedicated server be present.

Only in the client$-$server model can file transfers occur

Every device in a peer$-$to$-$peer network can function as a client or a server.
