Internet
The global collection of interconnected networks used for both private
and business communications.
intranet
A private, company-internal network that looks like part of the Internet
(users access information using web browsers), but is accessible only
by employees.
IP
See TCP/IP
.
IP address
Internet Protocol address
The address of a host (computer) on the Internet, consisting of four
numbers, each from 0 to 255, separated by periods, e.g.,
209.191.4.240. An IP address consists of a
network ID
that identifies
the particular network the host belongs to, and a
host ID
uniquely
identifying the host itself on that network. A network mask is used to
define the network ID and the host ID. Because IP addresses are
difficult to remember, they usually have an associated domain name
that can be specified instead. See
domain name, network mask
.
ISP
Internet Service Provider
A company that provides Internet access to its customers, usually for
a fee.
LAN
Local Area Network
A network limited to a small geographic area, such as a home or small
office.
LED
Light Emitting Diode
An electronic light-emitting device. The indicator lights on the front of
the Wireless Gateway are LEDs.
MAC address
Media Access Control address
The permanent hardware address of a device, assigned by its
manufacturer. MAC addresses are expressed as six pairs of hex
characters, with each pair separated by colons. For example;
NN:NN:NN:NN:NN:NN
.
mask
See network mask
.
Mbps
Abbreviation for Megabits per second, or one million bits per second.
Network data rates are often expressed in Mbps.
NAT
Network Address Translation
A service performed by many routers that translates your network’s
publicly known IP address into a
private
IP address for each computer
on your LAN. Only your router and your LAN know these addresses;
the outside world sees only the public IP address when talking to a
computer on your LAN.
network
A group of computers that are connected together, allowing them to
communicate with each other and share resources, such as software,
files, etc. A network can be small, such as a
LAN
, or very large, such
as the
Internet
.
network mask
A network mask is a sequence of bits applied to an IP address to
select the network ID while ignoring the host ID. Bits set to 1 mean
"select this bit" while bits set to 0 mean "ignore this bit." For example, if
the network mask 255.255.255.0 is applied to the IP address
100.10.50.1, the network ID is 100.10.50, and the host ID is 1. See
binary, IP address, subnet
.
NIC
Network Interface Card
An adapter card that plugs into your computer and provides the
physical interface to your network cabling. For Ethernet NICs this is
typically an RJ-45 connector. See
Ethernet, RJ-45
.
packet
Data transmitted on a network consists of units called packets. Each
packet contains a payload (the data), plus overhead information such
