Media access control (MAC) address
A standardized data-link-layer address that is required for every port or
device that connects to a LAN. Other devices in the network use these
addresses to locate specific ports in the network, and to create and
update routing tables and data structures. MAC addresses are six bytes
long and are controlled by the IEEE. Also known as a hardware address,
a MAC-layer address and a physical address.
When your computer is connected to the Internet, a correspondence
table relates your IP address to your computer's physical (MAC) address
on the network
Name server
A program that constitutes the server half of the DNS client-server
mechanism. A name server contains information about a segment of the
DNS database and makes it available to a client called a resolver. A
resolver is often just a library routine that creates queries and sends
them across a network to a name server.
NAT
see Network Address Translation (NAT)
Netmask
see subnet mask
Network Address Translation (NAT)
A mechanism for reducing the need for globally unique IP addresses.
NAT allows an organization with addresses that are not globally unique
to connect to the Internet by translating those addresses into globally
routable address space. Also known as Network Address Translator.
Network Time Protocol (NTP)
A protocol built on top of the Transmission Control Protocol (TCP) that
synchronizes the time of a local computer client or server to radio clocks
and atomic clocks located on the Internet. This protocol is capable of
synchronizing distributed clocks within milliseconds over long time
periods. Some configurations include cryptographic authentication to
prevent accidental or malicious protocol attacks.
