NAT
A technique by which several hosts share a single IP address for access to the Internet.
NetBIOS
Network Basic Input Output System. An application programming interface (API)
for sharing services
and information on l
ocal-area networks (LANs). Provides for communication between stations of a
network where each station is given a name. These names are alphanumeric names, 16 characters in length.
netmask
Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local
to it, and which must be reached through a gateway or router.
A number that explains which part of an IP address comprises the network address and which part is the host
address on that network. It can be expressed in dotted-decimal notation or as a number appended to the IP
address. For example, a 28-bit mask starting from the MSB can be shown as 255.255.255.192 or as /28
appended to the IP address.
Network Address Translation
A technique by which several hosts share a single IP address for access to the Internet.
packet
A block of information sent over a network. A packet typically contains a source and destination network
address, some protocol and length information, a block of data, and a checksum.
Point-to-Point Protocol
PPP. A protocol allowing a computer using TCP/IP to connect directly to the Internet.
RADIUS
Short for Remote Authentication Dial-In User Service, RADIUS is an authentication system.
Using RADIUS, you must enter your user name and password before gaining access to a network. This
information is passed to a RADIUS server, which checks that the information is correct, and then authorizes
access. Though not an official standard, the RADIUS specification is maintained by a working group of the
IETF.
RIP
A protocol in which routers periodically exchange information with one another so that they can determine
minimum distance paths between sources and destinations.
router
A device that forwards data between networks. An IP router forwards data based on IP source and
destination addresses.
