IP Address – In the most widely installed level of the Internet Protocol (IP)
today, and 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. This utility is commonly used under Windows NT
and 2000, for configuring networks with a static IP address.
IPSec – IPSec (Internet Protocol Security) is a developing standard for
security at the network or packet-processing layer of network communication.
A big advantage of IPSec is that security arrangements can be handled without
requiring changes to individual user computers.
IRQ (Interrupt ReQuest) – A hardware interrupt on a PC. There are 16 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.

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
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.
Link Quality – Indicates the Quality of data being received.
MAC Address – The MAC (Media Access Control) address is a unique
number 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.
Mbps (Megabits per Second) – One million bits per second; a unit of
measurement of the speed of data transmission.
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.
