Intranet This is a private network, inside an organization or company that

uses the same software you will find on the public Internet. The

only difference is that an Intranet is used for internal usage only.

Internet The Internet is a globally linked system of computers that are

logically connected based on the Internet Protocol (IP). The

Internet provides different ways to access private and public

information worldwide.

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. When you

“call” that number, using any connection methods, you get

connected to the computer that “owns” that IP address.

ISP ISP (Internet Service Provider)

is a company that maintains a

network that is linked to the Inte

rnet 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.

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.

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.

MJPEG MJPEG (Motion JPEG) composes a moving image by storing

each frame of a moving picture sequence in JPEG compression,

and then decompressing and displaying each frame at rapid

speed to show the moving picture.
