Client Process

A client process uses an ephemeral port, a random port number ranging from 32768 to 61000 on Linux, and from 49152 to 65535 on Windows, used for temporary connections.

Only one process can use one port number at a time.

Peer-to-Peer processes

peer-to-peer process
A process where the client and the server are both in one process. These are multithreaded, where the server thread listens on a well known port, and each client thread connects to a different server.
