Glossary
Access Point: An internetworking device that seamlessly connects wired and
wireless networks.
Ad-Hoc: An independent wireless LAN network formed by a group of computers,
each with a network adapter.
ASCII: American Standard Code for Information Interchange, ASCII, is one of the two
formats that you can use for entering the values for WEP key. It represents English
letters as numbers from 0 to 127.
Authentication Type: Indication of an authentication algorithm which can be
supported by the Access Point:
1. Open System: Open System authentication is the simplest of the available
authentication algorithms. Essentially it is a null authentication algorithm. Any station
that requests authentication with this algorithm may become authenticated if 802.11
Authentication Type at the recipient station is set to Open System authentication.
2. Shared Key: Shared Key authentication supports authentication of stations as
either a member of those who knows a shared secret key or a member of those who
does not.
Backbone: The core infrastructure of a network, which transports information from
one central location to another where the information is unloaded into a local system.
Bandwidth: The transmission capacity of a device, which is calculated by how much
data the device can transmit in a fixed amount of time expressed in bits per second
(bps).
Beacon: A beacon is a packet broadcast by the Access Point to keep the network
synchronized. Included in a beacon are information such as wireless LAN service
area, the AP address, the Broadcast destination addresses, time stamp, Delivery
Traffic Indicator Maps, and the Traffic Indicator Message (TIM).
Bit: A binary digit, which is either -0 or -1 for value, is the smallest unit for data.
Browser: An application program that enables one to read the content and
interact in the World Wide Web or Intranet.
BSS: BSS stands for “Basic Service Set”. It is an Access Point and all the LAN PCs
that associated with it.
Channel: The bandwidth which wireless Radio operates is divided into several
segments, which we call them “Channels”. AP and the client stations that it associated
work in one of the channels.
CSMA/CA: In local area networking, this is the CSMA technique that combines slotted
time -division multiplexing with carrier sense multiple access/collision detection
