10BaseT - Physical Layer Specification for Twisted-Pair Ethernet using Unshielded Twisted Pair wire at
0Mbps. This is the most popular type of LAN cable used today because it is very cheap and easy to

Category 3, 4 and 5. CAT 3 TP (Twisted Pair) cable has a network data transfer rate of up to 10Mbps.

Access Point - A device that is able to receive wireless signals and transmit them to the wired
network, and vice versa - thereby creating a connection between the wireless and wired networks.
Ad Hoc - An ad hoc wireless LAN is a group of computers, each with LAN adapters, connected as an
independent wireless LAN.
Adapter - A device used to connect end-user nodes to the network; each contains an interface to a specific
etc. type of computer or system bus, e.g. EISA, ISA, PCI, PCMCIA, CardBus,
Auto-Negotiation - A signaling method that allows each node to define its operational mode (e.g., 10/100
Mbps and half/full duplex) and to detect the operational mode of the adjacent node.
Backbone - The core infrastructure of a network. The portion of the network that transports information
from one central location to another central location where it is unloaded onto a local system.
Base Station - In mobile telecommunications, a base station is the central radio transmitter/receiver that

maintains communications with the mobile radiotelephone sets within its range. In cellular and perso
communications applications, each cell or micro-cell has its own base station; each base station in t
interconnected with other cells' bases.
Bitmap – A Windows and OS/2 bitmapped graphics file format. Bitmap files provide formats for 2, 16,
256, or 16 million colors. It uses the extension .BMP.
BSS - BSS stands for "Basic Service Set". It is an Access Point and all the LAN PCs that are
associated with it.
