1. Intranets.
Intranets are network of work stations (PCs) who share information within limit area such as office floors or neighborhood buildings. Several workstations are connected through a high performance computer called server. Server acts as a regulator of intranet which has ability to allow or restrict access to information contained its hard drive in the form of database. Several hardware and software are required to establish intranet such networking cables, hubs, intranet server software (Windows server 2008), database management server based software (SQL) and intranet browsers just like internet browsers.


2. Extranets.
Extranet is similar to intranets in its basics but its scope is wider than intranet. It allow outsiders such as suppliers and customers to have access to information and update it when required. Extranet also connects the various intranets. Extranet can be used within the city or country depending on the communication network available such as telephone lines or satellite signals. Ordinary cable connections are not suitable for establishing extranets. Common example extranets are supermarkets where computer at point of sale is connected with suppliers computer and its own intranet. So the supplier access to information on sales demand and supplier can automatically get purchase order based on predefined inventory level.


3. Internet.
Internet is largest and complex form of network. Internet connects all the intranet, extranets and stand alone computers to form the global network known as internet. Websites are the information banks saved on web server which allows visitors access to its database containing files or web pages with the permission of its owner. Various intermediaries are involved in information sharing process like your ISP (internet service provider), information which you demand typing specific URL (universal resource locator) is passed through your ISPs high performance computer which has control over what you can access or not.
