Sockets

Definition

(Context: General)


Virtual connections between processes. They can be of two types, stream (bi-directional) or datagram (fixed-length destination-addressed messages). The socket library function socket() creates a communications end-point or socket and returns a file descriptor with which to access that socket. The socket has associated with it a socket address, consisting of a port number and the local host's network address.
