IEEE 802

IEEE 802 is a family of standards developed by the Institute of Electrical and Electronics Engineers (IEEE) for defining Local Area Network (LAN) and Metropolitan Area Network (MAN) technologies. It was formed in 1980 and has since become one of the most influential and widely used networking standards worldwide. The IEEE 802 standards cover a broad range of topics, including data link layer protocols, physical layer specifications, and network management protocols. These standards enable the smooth and efficient functioning of various communication technologies, fostering seamless connectivity across devices and systems.

The history of the origin of IEEE 802 and the first mention of it

The history of IEEE 802 dates back to the early 1980s when there was a need to standardize LAN technologies to enable interoperability and scalability. During this time, Ethernet, a widely adopted LAN technology, was gaining popularity, but it lacked a standardized specification. To address this issue, Dr. Robert M. Metcalfe founded the Ethernet Technical Committee (ETC) in 1980. Later, in 1983, the ETC became part of the IEEE, leading to the creation of the IEEE 802 project.

The first official mention of IEEE 802 occurred in 1983 when the IEEE established a new committee called the IEEE 802 LAN/MAN Standards Committee. This committee was tasked with developing and maintaining networking standards within the 802 family.
