JAVA Java is a programming language that is specially designed for
writing programs that can be safely downloaded to your computer
through the Internet without the fear of viruses. It is an object-
oriented multi-thread programming best for creating applets and
applications for the Internet, Intranet and other complex, distributed

L
LAN Local Area Network a computer network that spans a relatively
small area sharing common resources. Most LANs are confined to a
single building or group of buildings.
N
NAT Network Address Translator generally applied by a router, that
makes many different IP addresses on an internal network appear
to the Internet as a single address. For routing messages properly
within your network, each device requires a unique IP address. But
the addresses may not be valid outside your network. NAT solves
the problem. When devices within your network request information
from the Internet, the requests are forwarded to the Internet under
the router’s IP address. NAT distributes the responses to the proper
IP addresses within your network.
Network A network consists of a collection of two or more devices, people,
or components that communicate with each other over physical or
virtual media. The most common types of network are:
LAN – (local area network): Computers are in close distance to one another. They are usually in
the same office space, room, or building.
WAN – (wide area network): The computers are in different geographic locations and are
connected by telephone lines or radio waves.
NWay Protocol A network protocol that can automatically negotiate the highest
possible transmission speed between two devices.
P
PING Packet Internet Groper, a utility used to determine whether a
specific IP address is accessible. It functions by sending a packet
to the specified address and waits for a reply. It is primarily used to
troubleshoot Internet connections.
PPPoE Point-to-Point Protocol over Ethernet. PPPoE is a specification
