3-1-3 Relationship Between Connected Devices

The relationship between the connected devices of LAN is classified into client/server type and peer-to-peer type. In the client/server type, there is a clear vertical relationship between the connected devices. Specifically, it is configured by the client that requests the processing (or requests the service), and the server that performs the processing (or provides the service).
