IEEE 802 refers to a family of IEEE standards dealing with local area networks and metropolitan area networks. The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international Non-profit, professional organization Metropolitan area network s or MAN s are large Computer networks usually spanning a city More specifically, the IEEE 802 standards are restricted to networks carrying variable-size packets. (By contrast, in cell-based networks data is transmitted in short, uniformly sized units called cells. Isochronous networks, where data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also out of the scope of this standard. Isochronous: From Greek iso, equal + Chronos, time It literally means to occur at the same time or at equal time intervals ) The number 802 was simply the next free number IEEE could assign, though "802" is sometimes associated with the date the first meeting was held - February 1980.

The services and protocols specified in IEEE 802 map to the lower two layers (Data Link and Physical) of the seven-layer OSI networking reference model. The Open Systems Interconnection Basic Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer Network protocol In fact, IEEE 802 splits the OSI Data Link Layer into two sub-layers named Logical Link Control (LLC) and Media Access Control, so that the layers can be listed like this:

• Data link layer
  • LLC Sublayer
  • MAC Sublayer
• Physical layer

The IEEE 802 family of standards is maintained by the IEEE 802 LAN/MAN Standards Committee (LMSC). According to the IEEE 802 family of standards Logical Link Control ( LLC) is the upper sublayer of the OSI Data Link Layer. The Media Access Control (MAC Data communication protocol sub-layer also known as the Medium Access Control is a sublayer of the Data Link Layer specified in the The Data Link Layer is Layer 2 of the seven-layer OSI model. It responds to service requests from the Network Layer and issues service requests to the According to the IEEE 802 family of standards Logical Link Control ( LLC) is the upper sublayer of the OSI Data Link Layer. The Media Access Control (MAC Data communication protocol sub-layer also known as the Medium Access Control is a sublayer of the Data Link Layer specified in the The Physical Layer is the first level in the seven-layer OSI model of computer networking. The most widely used standards are for the Ethernet family, Token Ring, Wireless LAN, Bridging and Virtual Bridged LANs. An individual Working Group provides the focus for each area. Working Group can mean Working group, an interdisciplinary group of researchers or Working Group (dogs, kennel club designation for
