Socket often refers specifically to an internet socket or TCP socket. An internet socket is minimally characterized by the following: local socket address, consisting of the local IP address and (for TCP and UDP, but not IP) a port number; protocol: A transport protocol, e.g., TCP, UDP, raw IP.
A Berkeley socket is an application programming interface (API ... Raw sockets provide a simple interface that bypasses the processing by the host's TCP/IP stack.
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.
Trumpet Winsock is a TCP/IP stack for Windows 3.x that implemented the Winsock API, which is an API for network sockets. [1] It was developed by Peter Tattam from Trumpet Software International and distributed as shareware software. [2]
The TCP checksum is a weak check by modern standards and is normally paired with a CRC integrity check at layer 2, below both TCP and IP, such as is used in PPP or the Ethernet frame. However, introduction of errors in packets between CRC-protected hops is common and the 16-bit TCP checksum catches most of these.
TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses, [ 1 ] However, many unofficial uses of both well-known and registered port ...
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 ...
lwIP (lightweight IP) is a widely used open-source TCP/IP stack designed for embedded systems. lwIP was originally developed by Adam Dunkels at the Swedish Institute of Computer Science and is now developed and maintained by a worldwide network of developers.
