J 
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 
network.
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 
for connecting the users on an Ethernet to the Internet through a 
common broadband medium, such as DSL or cable modem. All the 
users over the Ethernet share a common connection.
