802.11x
An IEEE specification that defines wireless LAN (WLAN) data link and physical
layers. The specification includes data link layer media access control (MAC)
sub-layer, and two sub-layers of the physical (PHY) layer-a frequency-hopping
spread-spectrum (FHSS). See also, FHSS.
802.2
IEEE specification that describes the logical link control (LLC) encapsulation
common to all 802 series LANs.
802.3
An IEEE LAN specification for a Carrier Sense Multiple Access with Collision
Detection (CSMA-CD) Ethernet network. The standard describes physical
media. An 802.3 frame uses source and destination media access control (MAC)
addresses to identify its originator and receiver(s).
authentication
The process that a station, device, or user employs to announce its identify to
the network which validates it. IEEE 802.11 specifies two forms of
authentication: open system and shared key. See also, 802.11x and
authentication.
authorization
The process of deciding if device 'X' may use network service 'Y'. Trusted
devices (the devices that are both authenticated and authorized) are allowed
access to network services. Unknown (not trusted) devices may require further
user authorization to access network services. This does not principally exclude
that the authorization might be given by an application automatically.
Authorization always includes authentication. See also, authentication.
bandwidth
Specifies the amount of the frequency spectrum that is usable for data transfer.
In other words, it identifies the maximum data rate a signal can attain on the
medium without encountering significant attenuation (loss of power). See also,
bit rate.
