resources of a single processor or server within a small geographic area (for
example, within an office building).
Latency
- The time delay between when the first bit of a packet is received and
the last bit is forwarded.
MAC Address
- The MAC (Media Access Control) address is a unique num-
ber assigned by the manufacturer to any Ethernet networking device, such as a
network adapter, that allows the network to identify it at the hardware level.

MD5
- A type of one-way authentication method that uses passwords. MD5
authentication is not as secure as the EAP-TLS or EAP/TTLS authentication
methods. MD5 authentication does not support dynamic WEP key manage-
ment.

port, also known as an uplink port, connects to another hub or switch using a
straight-through cable. To connect a MDI port to a computer, use a crossover
cable.

mIRC
- mIRC runs under Windows and provides a graphical interface for log-
ging onto IRC servers and listing, joining, and leaving channels.
Motherboard
- A motherboard is the physical arrangement in a computer that
contains the computer’s basic circuitry and components.
Multicasting
- Sending data to a group of nodes instead of a single destination.
NAT
- NAT (Network Address Translation) is the translation of an Internet
Protocol address (IP address) used within one network to a different IP address
known within another network. One network is designated the inside network
and the other is the outside.

a corporation scale, or when it is necessary to connect the wired and wireless
networks.
IP Address
- In the most widely installed level of the Internet Protocol (IP)
today, an IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packets across the Internet. When you
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP
includes your IP address in the message (actually, in each of the packets if more
than one is required) and sends it to the IP address that is obtained by looking
up the domain name in the Uniform Resource Locator you requested or in the
e-mail address you're sending a note to. At the other end, the recipient can see
the IP address of the Web page requestor or the e-mail sender and can respond
by sending another message using the IP address it received.
IPCONFIG
- A utility that provides for querying, defining and managing IP
addresses within a network. A commonly used utility, under Windows NT and
2000, for configuring networks with static IP addresses.
IPSec

secure exchange of packets at the IP layer. IPSec supports two basic modes:
Transport and Tunnel. Transport encrypts the payload of each packet, leaving
the header untouched, while Tunnel mode encrypts both the header and the pay-
load and is therefore more secure. IPSec must be supported on both transmit-
ter and receiver and must share a public key. Tunnel mode is widely deployed
in VPNs (Virtual Private Networks).
IRQ

lines used to signal the CPU that a peripheral event has started or terminated.
Except for PCI devices, two devices cannot use the same line.
ISM band
- The FCC and their counterparts outside of the U.S. have set aside
bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical)
band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made avail-
able worldwide. This presents a truly revolutionary opportunity to place con-
venient high-speed wireless capabilities in the hands of users around the globe.
ISP
- An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as website
building and virtual hosting.
LAN
- A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
