socket - Computer Definition
- An operating system (OS) abstraction that permits application programs to access communications protocols automatically. Bolt Beranek and Newman (now BBN Technologies) developed the concept in conjunction with the company's early work on TCP/IP. See also application, OS, program, protocol, and TCP/IP.
- Comprising a node address and a port number, a socket is an identifier for a service on a node. In combination a socket on an originating node and a socket on a destination node establish an application session. An Internet Protocol (IP) addressable client and server, for example, might engage in an e-mail transfer using SMTP (Simple Mail Transfer Protocol), which is well-known port 25. See also application, client, IP, node, port, server, session, SMTP, SOCKS, and well-known port.
Is roughly analogous to a port and is a communication endpoint for a TCP or UDP connection. One process is said to open a socket to listen for incoming connections, and a second process connects to a socket to establish a communication session.
Sockets can also be used for interprocess communication on a single computer, and multiple sockets can be made to communicate with one another. Sockets are bidirectional, which means that both sides of the connection can send and receive information.
