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.
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.
A network mask is a sequence of bits applied to an IP address to
select the network ID while ignoring the host ID. A bits set to 1
means "select this bit" while a bit set to 0 means "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.
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.
Data transmitted on a network consists of units called packets.
Each packet contains a payload (the data), plus overhead
information such as where it comes from (source address) and
where it should go (destination address).
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.
A physical access point to a device such as a computer or
router, through which data flows into and out of the device.
A protocol for serial data transmission that is used to carry IP
(and other protocol) data between your ISP and your computer.
The WAN interface on the ADSL router uses two forms of PPP
called PPPoA and PPPoE. See also PPPoA, PPPoE.
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoE. You can define
only one PPPoA interface per VC.
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoA. You can define
one or more PPPoE interfaces per VC.
A set of rules governing the transmission of data. In order for a
data transmission to work, both ends of the connection have to
follow the rules of the protocol.
In a physically separate location. For example, an employee
away on travel who logs in to the company's intranet is a remote
user.
The standard plug used to connect telephones, fax machines,
modems, etc. to a telephone port. It is a 6-pin connector usually
containing four wires.
