IEEE 802 委员会成立于 1980 年 2 月
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LAN), personal area network (PAN), and metropolitan area networks (MAN).
The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently Active.
The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer Open Systems Interconnection (OSI) networking reference model. IEEE 802 divides the OSI data link layer into two sub-layers: logical link control (LLC) and medium access control (MAC)
The most widely used of these standards are for the Ethernet family, Token Ring, wireless network protocols (including Wi-Fi), and bridging protocols
