Overview
A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system. Unix domain sockets support transmission of a reliable stream of bytes (SOCK_STREAM), similar to TCP. In addition, they support ordered and reliable transmission of datagrams (SOCK_SEQPACKET), or unordered and unreliable transmission of datagrams SOCK_DGRAM, similar to UDP. The Unix domain socket facility is a standard component of POSIX operating systems.
