The Protocol Wars were a long-running debate in computer science that occurred from the 1970s to the 1990s, when engineers, organizations and nations became polarized over the issue of which communication protocol would result in the best and most robust networks. This culminated in the Internet–OSI Standards War in the 1980s and early 1990s, which was ultimately "won" by the Internet protocol suite (TCP/IP) by the mid-1990s when it became the dominant protocol suite through rapid adoption of the Internet.
In the late 1960s and early 1970s, the pioneers of packet switching technology built computer networks providing data communication, that is the ability to transfer data between points or nodes. As more of these networks emerged in the mid to late 1970s, the debate about communication protocols became a "battle for access standards". An international collaboration between several national postal, telegraph and telephone (PTT) providers and commercial operators led to the X.25 standard in 1976, which was adopted on public data networks providing global coverage. Separately, proprietary data communication protocols emerged, most notably IBM's Systems Network Architecture in 1974 and Digital Equipment Corporation's DECnet in 1975.
Protocols
https://en.m.wikipedia.org/wiki/Communication_protocol
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics, and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.[1]
Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses predetermined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved.[2] To reach an agreement, a protocol may be developed into a technical standard. 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]
Multiple protocols often describe different aspects of a single communication. A group of protocols designed to work together is known as a protocol suite; when implemented in software they are a protocol stack.
Internet communication protocols are published by the Internet Engineering Task Force (IETF). The IEEE (Institute of Electrical and Electronics Engineers) handles wired and wireless networking and the International Organization for Standardization (ISO) handles other types. The ITU-T handles telecommunications protocols and formats for the public switched telephone network (PSTN). As the PSTN and Internet converge, the standards are also being driven towards convergence.
Standards
Computer hardware and software standards are technical standards instituted for compatibility and interoperability between software, systems, platforms and devices.
https://en.m.wikipedia.org/wiki/Software_standard
A software standard is a standard, protocol, or other common format of a document, file, or data transfer accepted and used by one or more software developers while working on one or more than one computer programs. Software standards enable interoperability between different programs created by different developers.
Representatives from standards organizations, like W3C[4] and ISOC,[5] collaborate on how to make a unified software standard to ensure seamless communication between software applications. These organisations consist of groups of larger software companies like Microsoft and Apple Inc.
The complexity of a standard varies based on the specific problem it aims to address but it needs to remain simple, maintainable and understandable. The standard document must comprehensively outline various conditions, types, and elements to ensure practicality and fulfill its intended purpose. For instance, although both FTP (File Transfer Protocol) and SMTP (Simple Mail Transfer Protocol) facilitate computer-to-computer communication, FTP specifically handles the exchange of files, while SMTP focuses on the transmission of emails.
A standard can be a closed standard or an open standard. The documentation for an open standard is open to the public and anyone can create a software that implements and uses the standard. The documentation and specification for closed standards are not available to the public, enabling its developer to sell and license the code to manage their data format to other interested software developers. While this process increases the revenue potential for a useful file format, it may limit acceptance and drive the adoption of a similar, open standard instead.[6]
