Internet, Intranet,and Extranet :-
Internet, intranet, and Extranet are three terms that describe "Internet-type" applications that are used by an organization, but how do you know if web application is part of your intranet or part of the internet?
Internet :- If you wish to expose information to everyone in the world, then you world build an internet-type application. An internet -type application used internet protocols such as HTTP, FTP, or SMTP and is available to person's anywhere on the internet. We use the internet and web application as ways to extend who the application can reach. For example, I no longer need to go to the bank to transfer funds. Because the bank has built a web site on the internet, I can do that from the comfort of my own home.
Intranet:- An applica7is considered to be on the company's intranet if is using Internet -type protocols such as HTTP or FTP but the application is available only within the company. The information on a company's intranet would not be accessible to person's on the internet because it is not for public use. For example, adequate years ago I was sitting with my banking officer going over my account and noticed that the bank had moved all of its customer
Account information to a web site and that banking officer was using a web browser to retrieve my account details. Although the application was being used by a wave browser, it was still an "internal" application meant only for banking officers.
Extranet :-From time to time, an application that has been built for the company's internet and used by internal employee's will need to be extended to select business partners or customers. If you extend your intranet out to select business partners or customers, you have created an Extranet. An Extranet cannot be used by anyone else external to the company except for those selected individuals. Figure 1-3 displays the basic configurations of internet, intranet, and Extranet.
This section has introduction you to some terms such as per-to-peer versus server-based networking , internet, intranet, and Extranet; now let's look at how the network is out with the different network topologies!
