Internet address
To participate in Internet communications and on Internet Protocol-based networks, a node must
have an Internet address that identifies it to the other nodes. All Internet addresses are IP
addresses
IP
Internet Protocol is the standard that describes the layout of the basic unit of information on the
Internet (the
packet
) and also details the numerical addressing format used to route the
information. Your Internet service provider controls the IP address of any device it connects to
the Internet. The IP addresses in your network must conform to IP addressing rules. In smaller
LANs, most people will allow the DHCP function of a router or gateway to assign the IP
addresses on internal networks.
IP address
IP address is a 32-binary digit number that identifies each sender or receiver of information that
is sent in packets across the Internet. For example 80.80.80.69 is an IP address, it is the closet
thing the Internet has to telephone numbers. When you “call” that number, using any connection
methods, you get connected to the computer that “owns” that IP address.
ISP
Internet Service Provider, is a company that maintains a network that is linked to the Internet by
way of a dedicated communication line. An ISP offers the use of its dedicated communication
lines to companies or individuals who can’t afford the high monthly cost for a direct connection.
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.

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
