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.
Most socket application programming interfaces (APIs), for example, those based on Berkeley sockets, support raw sockets. Windows XP was released in 2001 with raw socket support implemented in the Winsock interface, but three years later, Microsoft limited Winsock's raw socket support because of security concerns. [7]
[3] [5] As a result of deliberations by the Austin Group with the goal of bringing flavors of UNIX that do not provide STREAMS, such as BSD and Linux, under the Single UNIX Specification, the UNIX 03 Single UNIX Specification both declares STREAMS as optional, and declares POSIX Sockets as the preferred API for new transport protocols.
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.
Unix Network Programming is a book written by W. Richard Stevens. [1] It was published in 1990 by Prentice Hall and covers many topics regarding UNIX networking and Computer network programming . The book focuses on the design and development of network software under UNIX.
Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by application programming interface (API). Examples of the connection-oriented protocols include Transmission Control Protocol (TCP) and Sequenced Packet Exchange (SPX), and examples of connectionless protocols include User ...

Windows Sockets code and design are based on BSD sockets, but provides additional functionality to allow the API to comply with the regular Windows programming model. The Windows Sockets API covered almost all the features of the BSD sockets API, but there were some unavoidable obstacles which mostly arose out of fundamental differences between ...
