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 bundled into a specific format to enable transmission on a
network. A packet contains a payload (the data) and 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.
PPP Point-to-Point Protocol
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 Ethernet Modem Router uses two
forms of PPP called PPPoA and PPPoE. See also PPPoA,
PPPoE.
PPPoA Point-to-Point Protocol over ATM
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.
PPPoE Point-to-Point Protocol over Ethernet
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.
protocol 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.
RADIUS Remote Authentication Dial-In User Service
A protocol used to authenticate users dialing in or otherwise
connecting to a network. RADIUS specifies the series of
requests, challenges, and response messages required before a
device can gain access to a network.
RIP Routing Information Protocol
The original TCP/IP routing protocol. There are two versions of
RIP: version I and version II.
