Berkeley sockets originated with the 4.2BSD Unix operating system, released in 1983, as a programming interface. Not until 1989, however, could the University of California, Berkeley release versions of the operating system and networking library free from the licensing constraints of AT&T Corporation 's proprietary Unix.
Development of application programs that utilize this API is called socket programming or network programming. Internet socket APIs are usually based on the Berkeley sockets standard. In the Berkeley sockets standard, sockets are a form of file descriptor, due to the Unix philosophy that "everything is a file", and the analogies between sockets ...
The Berkeley Packet Filter (BPF; also BSD Packet Filter, classic BPF or cBPF) is a network tap and packet filter which permits computer network packets to be captured and filtered at the operating system level.
Network programming traditionally covers different layers of OSI/ISO model (most of application-level programming belongs to L4 and up). The table below contains some examples of popular protocols belonging to different OSI/ISO layers, and popular APIs for them.
After instantiating a new socket, the server binds the socket to an address. For a Unix domain socket, the address is a /path/filename.. Because the socket address may be either a /path/filename or an IP_address:Port_number, the socket application programming interface requires the address to first be set into a structure.

Only Windows gets this wrong. Should non-standard terminology be used when writing about socket programming, because someone failed to correctly implement the standard we're writing about? bind() is used on the server side, and associates a socket descriptor with a socket address structure, i.e. a specified local port number and IP address.
Java [2] In computer science , Linda is a coordination model that aids communication in parallel computing environments. Developed by David Gelernter , it is meant to be used alongside a full-fledged computation language like Fortran or C where Linda's role is to " create computational activities and to support communication among them".
