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 | To participate in Internet communications and on 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 |
| 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. |

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 |
| 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. |

|
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. |
