socket

   <networking> The {Berkeley Unix} mechansim for creating a
   virtual connection between processes.  Sockets interface
   {Unix}'s {standard I/O} with its {network} communication
   facilities.  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.
