Mbps	Abbreviation for Megabits per second, or one million bits
	per second. Network data rates are often expressed in
	Mbps.
Microfilter	In splitterless deployments, a microfilter is a device that
	removes the data frequencies in the DSL signal, so that
	telephone users do not experience interference (noise)
	from the data signals. Microfilter types include in-line (in-
	stalls between phone and jack) and wall-mount (tele-
	phone jack with built-in microfilter). See also splitterless.
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 com-
	puter 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 pri-
	vate IP addresses on your LAN.
network	A group of computers that are connected together, al-
	lowing 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
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).
pingg­	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 ad-
	dress 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.
POTS	Plain Old Telephone Service Traditional analog telephone
	service using copper telephone lines. Pronounced pots.
	See also PSTN.
POTS splitter	See splitter.
