A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: protocols are to communication what programming languages are to computations. [3] An alternate formulation states that protocols are to communication what algorithms are to computation. [4]
Computer network programming involves writing computer programs that enable processes to communicate with each other ... is defined by the communication protocol, ...
Protocol (object-oriented programming), a common means for unrelated objects to communicate with each other (sometimes also called interfaces) Communication protocol, a defined set of rules and regulations that determine how data is transmitted in telecommunications and computer networking Cryptographic protocol, a protocol for encrypting messages
In version 4, the monolithic Transmission Control Program was divided into a modular architecture consisting of the Transmission Control Protocol and the Internet Protocol. [ 5 ] [ 6 ] This resulted in a networking model that became known informally as TCP/IP , although formally it was variously referred to as the DoD internet architecture ...
HTTP is a stateless application-level protocol and it requires a reliable network transport connection to exchange data between client and server. [20] In HTTP implementations, TCP/IP connections are used using well-known ports (typically port 80 if the connection is unencrypted or port 443 if the connection is encrypted, see also List of TCP ...
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking , and essentially establishes the Internet .
At the application layer, the TCP/IP model distinguishes between user protocols and support protocols. [1]: §1.1.3 Support protocols provide services to a system of network infrastructure. User protocols are used for actual user applications. For example, FTP is a user protocol and DNS is a support protocol.
In the context of the newly adopted layered protocol architecture (see OSI model), the definition of the protocol of a specific layer should be such that any entity implementing that specification in one computer would be compatible with any other computer containing an entity implementing the same specification, and their interactions should ...
