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

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

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

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

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