NetComm NS380W manual Java, Lan, Nat, Ping

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.
