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 also 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, office, or small
building.
LED Light Emitting Diode
An electronic light-emitting device. The indicator lights on the front of the
AAM6010EV-M 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 characters.
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.
NAT rule A defined method for translating between public and private IP addresses 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 also binary, IP address, subnet, "IP Addresses Explained" section.
NIC Network Interface Card
An adapter card that plugs into your computer and provides the physical interface
to your network cabling, which for Ethernet NICs 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 as where it came
from (source address) and where it should go (destination address).
ping Packet Internet (or Inter-Network) Groper
A program used to verify whether the host associated with an IP address is online.
It can also be used to reveal the IP address for a given domain name.
port A physical access point to a device such as a computer or router, through which
data flows into and out of the device
