# IEEE 802.1 defines Physical and Data Link Layer standards for
allowing one IEEE 802 LAN station to communicate with another
station on a different LAN or WAN.
IEEE 802.2 defines the Logical Link Control (LLC) sublayer of the
IEEE 802.x series. It is commonly used with IEEE 802.3, 802.4,
802.5, and 802.6 implementations.
# IEEE 802.2 adds header fields to identify which upper layer protocol
is used in the frame and which Network layer processes the frame’s
source and destination use.
# IEEE 802.3 specifies a variety of Physical layer options, including
different signaling modes (baseband and broadband), media types,
topologies, and data rates. The common element of each of the
options is their use of the Carrier Sense Multiple Access/Collision
Detection (CSMA/CD) media access method.
The individual implementations of 802.3 have been given names
that use a three-part naming convention. The first part is a number
that represents the data rate in megabits per second (Mbps). The
second part indicates BASE for baseband and BROAD for
broadband signals. The third part indicates a rough effective
distance or is used as a special designator.
# IEEE 802.4 was created, primarily, to satisfy the LAN needs of
factory and industrial automation. This standard defines a physical
bus topology, a token-passing media access method, both
baseband and broadband media, and 75 ohm CATV-type cable or
optical fiber.
# IEEE 802.5 is based on IBM’s Token-Ring specification. It uses a
token-passing media access method and supports data rates of 1,
4, or 16 Mbps. Unlike IBM’s Token-Ring, the 802.5 specification
does not mandate a specific transmission medium or physical
topology.

# IEEE 802.6 uses a data transfer technology called Distributed
Queue Dual Bus (DQDB) that allows both synchronous and
asynchronous traffic for supporting voice, video, and data
transmissions.
# IEEE 802.7 defines a standard for the design, installation, and test
parameters of broadband communication.
# IEEE 802.8 defines a Fiber Optic Technical Advisory Group to work
with the 802 working groups on fiber optic technology and
standards.
# IEEE 802.9, Isochronous Ethernet (also known as IsoEnet), focuses
on the integration of voice transmissions with data transmissions
and supports both sporadic and patterned traffic. This specification is rarely used.
# IEEE 802.10 defines a standard for services, protocols, data
formats, and interfaces that securely exchange data using
encryption mechanisms.
It also defines the management and distribution of encryption key
information. This standard is independent of any particular
encryption algorithm or transmission media.
# IEEE 802.11 defines standards for wireless LAN implementations
like spread-spectrum and infrared devices.
# IEEE 802.12 defines a 100 Mbps physical star topology
contention-based network standard known as 100VG-AnyLAN.
Unlike typical contention systems, 802.12 network devices will
contend for media access by signaling a hub. When multiple
simultaneous transmission requests occur, the hub grants
transmission rights to the highest priority traffic first.
# IEEE 802.12 will support both Ethernet and token ring frame types.
