COMPUTER NETWORKING

Detailed explanation-1: -In computing, the Windows Sockets API (WSA), later shortened to Winsock, is an application programming interface (API) that defines how Windows network application software should access network services, especially TCP/IP.

Detailed explanation-2: -Windows Socket API, also known as Winsock, is a type of application programming interface (API) used to communicate between Windows network software and network services. It’s primarily based on Transmission Control Protocol/Internet Protocol (TCP/IP), and derives its roots from the Berkeley Unix sockets interface.

Detailed explanation-3: -The Windows Socket API includes two interfaces. The first is an API for application developers to develop apps supporting networking. In contrast, the second API is a service provider interface used to set up new network protocols.

Detailed explanation-4: -Winsock follows the Windows Open System Architecture (WOSA) model; it defines a standard service provider interface (SPI) between the application programming interface (API), with its exported functions and the protocol stacks.
