7 Glossary
Access Point - An internetworking device that seamlessly connects wired and wireless
networks together.
Ad-Hoc - An Ad-Hoc wireless LAN is a group of computers each with wireless adapters,
connected as an independent wireless LAN.
Backbone - The part of a network that connects most of the systems and networks together and
handles the most data.
Bit - A binary digit. The value - 0 or 1 used in the binary numbering system. Also, the smallest
form of data.
BSS - Stands for Basic Service Set. An Access Point associated with several stations.
Domain - A subnetwork comprised of a group of clients and servers under the control of one
security database. Dividing LANs into domains improves performance and security.
DSSS - Direct Sequence Spread Spectrum is very widely known and the most used of the
spread spectrum types, owing most of its popularity to its ease of implementation and high data
rates.
Encryption - A security method that applies a specific algorithm to data in order to alter the
data’s appearance and prevent other devices from reading the information
ESS - Stands for Extended Service Set. More than one BSS can be configured as an Extended
Service Set. An ESS basically a roaming domain.
Ethernet - A popular local area data communications network, originally developed by Xerox
Corp., which accepts transmission from computers and terminals.
Ethernet operates on 10 Mbps baseband transmission over shielded coaxial cable or over
shielded twisted pair telephone wire.
Firmware - Code that is written onto read-only memory (ROM) or programmable read-only
memory (PROM). Once firmware has been written onto the ROM or PROM, it is retained even
when the device is turned off.
Fragmentation- Breaking a packet into smaller units when transmitting over a network medium
that cannot support the original size of the packet.
Infrastructure - An integrated wireless and wired LAN is called an infrastructure configuration.
IRQ - Interrupt ReQuest, A hardware interrupt on a PC. There are 16 IRQ lines used to signal
the CPU that peripheral event has started or terminated. In most cases, two devices cannot use
the same line.
PCMCIA - Personal Computer Memory Card International Association, which develops
standards for PC cards, formerly known as PCMCIA cards, are available in three types which
are about the same length and width as credit cards, but range in thickness from 3.3mm(Type I),
5.0mm(Type II), to 10.5mm(Type III).
These cards can be used for many functions, including memory storage, as landline modems
and as wireless LAN.
