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

Protocol stack of the OSI model. The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family.Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.

Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
This remains the dominant internetworking protocol in use in the Internet Layer; the number 4 identifies the protocol version, carried in every IP datagram. IPv4 is defined in RFC 791 (1981). Version number 5 was used by the Internet Stream Protocol, an experimental streaming protocol that was not adopted. [7] The successor to IPv4 is IPv6.
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 ...
