802.1q, 802.3, 802.11 (its families 11g, 11n, 11ax, 11be, …. ) every time we listen to this naming convention but what are these & how these are assigned? Let's discuss about this.
802 is a standard that was developed by the Institute of Electrical and Electronic Engineers (IEEE).
History - A brief.
The IEEE recognized the need to create some standards when local area networks (LANs) initially emerged as viable commercial tools in the late 1970s. To accomplish this, the IEEE founded Project 802, which was called after the year and month in which it was initiated (1980, February), and established a group to establish standards for local area network communication. "80" - "2" is the committee's identification number, which corresponds to the year and month in which it was formed. Although the IEEE 802 standards were released before the ISO standards, they were both in development at around the same time and shared information, resulting in the development of two compatible models.
The Project 802
Project 802 created network standards for the physical network components (interface devices and cabling) that are accounted for in the OSI reference model's physical and data-link layers. A number of independent committees have been created, each of which is in charge of setting standards in various areas of technology. The 802.11 committee (with many independent working groups) for wireless standards, the 802.1 committee for device interaction and security, and the 802.3 committee for Ethernet networking are all of particular relevance.
802.11 - Wireless
802.11 is the original wireless specification. Extensions of the 802.11 standards were given the same number with a letter suffix.
Wi-Fi is major source of communication for home use specially in WFH scenario, you may check details about WfH à LINK
Common 802.X Series
Project 802 has a number of subsections, including the following:
802.1: Internetworking standards
802.2: The logical link control (LLC) layer of the Open Systems Interconnection (OSI) reference model data-link layer
802.3: Ethernet (Carrier Sense Multiple Access with Collision Detection)
802.4: Token Bus LAN
802.5: Token Ring LAN
802.6: Metropolitan area network (MAN)
802.7: Broadband technologies
802.8: Fiber-optic technologies
802.9: Integrated voice/data networks
802.10: Network security standards and technologies
802.11: Wireless networking technologies and standards
802.12: Demand priority access technologies
802.14: Cable television access
802.15 wireless personal area network (WPAN) standards.
802.16 standards for broadband for wireless metropolitan area networks (WiMAX)
The Project 802 standards are constantly evolving, and new subcategories are being created to standardize new networking technologies.
The IEEE has made available IEEE 802 standards for free download. Under this program, a standard may be downloaded for free six months after the initial publication of the standard. All relevant IEEE 802.11 Standard, Amendments, and Recommended Practices are listed.
