A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
The client sends an HTTP request (method GET, version ≥ 1.1) and the server returns an HTTP response with status code 101 (Switching Protocols) on success.This means a WebSocket server can use the same port as HTTP (80) and HTTPS (443) because the handshake is compatible with HTTP.

A Berkeley socket is an application programming interface (API) for Internet domain sockets and Unix domain sockets, used for inter-process communication (IPC). It is commonly implemented as a library of linkable modules. It originated with the 4.2BSD Unix operating system, which was released in 1983.
The Lightstreamer Server is a high-performance engine that manages all the connections with the clients through the Internet. It integrates with the backend systems via custom adapters. The Data Adapter receives the real-time data flow from the data feed and injects it into the Lightstreamer Server.
The ZeroMQ API provides sockets (a kind of generalization over the traditional IP and Unix domain sockets), each of which can represent a many-to-many connection between endpoints. Operating with a message-wise granularity, they require that a messaging pattern be used, and are particularly optimized for that kind of pattern.
Update: Big Lots says it reached a deal in late December to keep hundreds of U.S. stores open. Big Lots is preparing to close all of its stores, the bankrupt discount retailer said Thursday. The ...
They presented the case for secure sockets and SNP performance results at the USENIX Summer Technical Conference on June 8, 1994. [6] [7] SNP was designed as an application sublayer on top of transport-layer sockets. It provides to Internet applications a secure sockets API that closely resembles the sockets API. The SNP approach was novel and ...
