3.  The Institute of Electrical and Electronics
Engineers (IEEE) is a professional association with its
corporate office in New York City and its operations
center in Piscataway, New Jersey. It was formed in
1963 from the amalgamation of the American Institute
of Electrical Engineers and the Institute of Radio
Engineers. Today, it is the world's largest association of
technical professionals with more than 420,000
members in over 160 countries around the world. Its
objectives are the educational and technical
advancement of electrical and electronic
engineering, telecommunications, computer
engineering and allied disciplines

4.  IEEE 802 is a family of IEEE standards dealing
with local area networks and metropolitan area
networks.
 More specifically, the IEEE 802 standards are
restricted to networks carrying variable-size packets.
By contrast, in cell relay 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.

5.  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. In fact,
IEEE 802 splits the OSI Data Link Layer into two sub-
layers named logical link control (LLC) and media access
control (MAC), so 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). 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.
