The IEEE 802 is a committee of the IEEE which describes a family of standards of relative lans and underground railway networks. More specifically, the standards IEEE 802 are limited to the networks using of the variable packages of sizes contrary to the networks in which the data are transmitted in cells of fixed size and generally short. Also untreated by the EEE 802: the networks isosynchrones where data are transmitted by groups of bytes to regular intervals.

The services and the specifications described by the IEEE 802 refer to the two sub-bases of the OSI model which contains seven of them, namely the physical Layer and the Course binder.
Dans the facts, the IEEE 802 cuts out the connection layer in two underlayers called Logical Link Control (LLC) and Media Access Control (MAC), so that the layers can be enumerated as follows:

Course binder

under layer LLC
under layer physical MAC

Layer

The standards IEEE 802 are maintained by the committee of standardization LAN/MAN (LMSC for LAN/MAN Standards Committee). The standards most largely widespread are the Ethernet, the Token-ring, ASFI (WiFi), the VLAN.

Each sector made for submission to a specific work group:

IEEE 802.1: Management of the lans, VLAN, authentification, etc
IEEE 802.2: Distinction between layer Logical Link Control (LLC) and Media Access Control (MAC)
IEEE 802.3: Media CSMA/CD Ethernet
IEEE 802.4 lay down: Lay down media CSMA/CA Token Bus and AppelTalk (used in Industrial data processing) (dissolved)
IEEE 802.5: Lay down media Token-ring (IBM)
IEEE 802.6: Group councils on the networks at long distance (Metropolitan Area Network or MAN) (dissolved)
IEEE 802.7: Group councils on the networks with Broad band (dissolved)
IEEE 802.8: Group councils on the networks on Fiberoptic (dissolved)
IEEE 802.9: Integrated services networks like ISDN (dissolved)
IEEE 802.10: Interworking of the safety of the LAN/MAN (dissolved)
IEEE 802.11: Wireless networkings: Infra-red, ASFI…
IEEE 802.12: Lans using the mechanism of request for priority
IEEE 802.13: not used
IEEE 802.14: Networks and Modem S cables (dissolved)
IEEE 802.15: Networks private without wire (WPAN) like Bluetooth
IEEE 802.16: Wireless networkings with broad band for example the Wi-max
IEEE 802.17: Optical fiber networks out of ring (Cancel Packet Ring)
IEEE 802.18: Group councils for the standardization of the radioelectric communications
IEEE 802.19: Group councils on the cohabitation with the other standards
IEEE 802.20: Wireless gateway with wide strip
IEEE 802.21: Automatic transfer of the connections independently of the media
IEEE 802.22: Regional networks without wire
