IP
Internet Protocol. The TCP/IP standard protocol that defines the
IP as a unit of information passed across an Internet and
provides the basis for packet delivery service. IP includes the
ICMP control and error message protocol as an integral part.
The entire protocol suite is often referred to as TCP/IP because
TCP and IP are the two most fundamental protocols.
IP address
Internet protocol address. This is a 32-bit address assigned to
host on a TCP/IP Internet. The IP address has a host
component and a network component.
L
LAN
Local Area Network. A data network intended to serve an area
of only a few square kilometers or less. Because the network is
known to cover only a small area, optimizations can be made in
the network signal protocols that permit data rates up to
100 Mb/s.
