Study Notes

The IEEE, ISO, and ITU-T are organizations involved in handling different types of communication standards, with IEEE focusing on wired and wireless networking, ISO on other types, and ITU-T on telecommunications protocols.
The first use of the term "protocol" in a data-commutation context was in a 1967 memorandum entitled "A Protocol for Use in the NPL Data Communications Network."
The ARPANET, the starting point for host-to-host communication in 1969, used the 1822 protocol for message transmission and Network Control Protocol (NCP) for higher-level communication.
Robert E. Kahn and Vint Cerf's research in the early 1970s led to the formulation of the Transmission Control Program (TCP), which was a monolithic design at the time.
The X.25 standard, based on virtual circuits, was developed in the late 1970s and contributed to the development of communication standards.
Computer manufacturers, such as IBM, Digital Equipment Corporation, and Xerox, developed proprietary protocols for their systems.
The TCP software was redesigned as a modular protocol stack in the 1980s, laying the foundation for the growth of TCP/IP as a comprehensive protocol suite.
The OSI model, a reference model for communication standards, was developed in 1984, leading to a debate over which standard would result in the best and most robust computer networks.
Communication protocols govern the exchange of information between devices through a network or other media and can be expressed by algorithms and data structures.
Systems typically use a set of cooperating protocols, known as a protocol suite, which can be arranged based on functionality and which operate at distinct layers.
Communication protocols can be divided into text-based and binary types, with text-based protocols representing content in human-readable format such as ASCII, UTF-8, XML, or JSON.
