The client-server model is a relationship between two computers in which one, the client, makes a request to a server that responds to the client's requests.

A client is a hardware or software component of a computing system that sends requests to a server.

The server processes the client's request, searches for the required data and sends it to the client.

Computers in peer-to-peer networks can act as both clients and servers.

Peer-to-peer networks do not have centralized control over resource sharing. Any of the computers can share their resources with any computer on the same network. Peer-to-peer relationships also mean that no computer has a higher priority for access or increased responsibility for sharing resources.
