10/100 Base-T: A technical term for Ethernet. 10/100 refers to the speed at which
the Ethernet network functions. 10 indicates 10 megabits per second (Mb/s) for
normal Ethernet, and 100 indicates 100 Mb/s for Fast Ethernet.
802.11a: A type of wireless networking that provides up to 54 Mb/s transmission in
the 5 GHz band.
802.11b: A type of wireless networking that provides up to 11 Mb/s transmission
(with a fallback to 5.5, 2 and 1 Mb/s) in the 2.4 GHz band.
802.11g: A type of wireless networking that provides up to 54 Mb/s transmission in
the 2.4 GHz band.
a
Ad hoc network:A type of wireless network in which devices directly communicate
with each other rather than through a Wireless Access Point (WAP). Ad hoc networks
are typically small and simple (for example, two wireless PCs or a wireless PC and a
wireless printer). Performance on these types of networks can degrade if more than
six devices are on the network. Ad hoc networks are also known as peer-to-peer
networks, independent basic service stations (IBSS), or direct-connect wireless
networks.
Authentication:Authentication is a wireless network security strategy. On a network
with authentication, devices use a shared key as a password and communicate only
with devices that know the key. Unlike WEP, authentication does not encrypt the data
sent between wireless devices. However, authentication can be used in conjunction
with WEP. Authentication keys and WEP keys can be identical.
AutoIP: A process by which a device on a network automatically assigns an IP
address to itself.
b
BOOTP: Bootstrap Protocol (BOOTP)is an Internet protocol that enables a device to
discover its own IP address, the IP address of a BOOTP server on the network, and a
file to be loaded into memory to boot the machine. This enables the device to boot
without requiring a hard or floppy disk drive.
Broadcast packet: A packet sent from one device on a network to all devices on the
network.
