But in contrast to TCP sockets, they only exist locally on the host. As such they cannot be used for inter-host-communication.

This page aims for usage of UNIX socket. Suppose process Resol waits for process Reep to send data. To initiate a communication, Resol has to setup a listening socket and waits for Reep.Reep creates a connecting socket, then connects Resol’s socket file. The AF_UNIX (also known as AF_LOCAL) socket family is used to communicate between processes on the same machine efficiently.

Sockets are supported by Unix, Windows, Mac, and many other operating syst Home A Unix Socket is used in a client-server application framework. A server is a process that performs some functions on request from a client. Most of the application-level protocols like FTP, SMTP, and POP3 make use of sockets to establish connection between client and server and then for exchanging data.
