supporting 128-, 192-, and 256-bit keys.
B
Basic Service Set Identifier (BSSID):
A unique identifier for each wireless client on a
wireless network. The BSSID is the Ethernet MAC address of each adapter on the
network.
Bit Rate:
The total number of bits (ones and zeros) per second that a network
connection can support. Note that this bit rate will vary, under software control, with
different signal path conditions.
Bluetooth:
An incompatible, very short-range lower speed communications system
(PAN), developed first in Europe as a "cable replacement" for printers and similar
peripheral connections. Its usage has expanded to include cordless earphones and
similar devices. It uses the 2.4 GHz ISM band, and "co-exists" with 802.11b. Here the
term, "co-exist" means that not all researchers agree on the amount of mutual
interference generated when both systems operate in the same location.
Broadcast SSID:
Used to allow an access point to respond to clients on a wireless
network by sending probes.
D
Data Rate (Information Rate):
Not all bits carry user information. Each group (packet) of
bits contains headers, trailers, echo control, destination information, and other data
required by the transmission protocol. It is important to understand the difference
between bit rate and data rate, since the overhead information may consume more than
40% of the total transmission. This difference is common to many such data systems,
including Ethernet.
Direct-Sequence Spread Spectrum (DSSS) and Frequency-Hop Spread Spectrum
(FHSS):
Two incompatible technologies used in radio transmission.
Dynamic IP Address:
An IP address that is automatically assigned to a client station in
a TCP/IP network, typically by a DHCP server. Network devices that serve multiple
users, such as servers and printers, are usually assigned static IP addresses.
