INTRANET Intranets are similar to the internet except that only selected individuals are allowed to access an intranet. Intranet is based on the client/server model. Intranets are extremely popular and low cost way to distribute corporate information. An intranet uses internet based protocols including TCP/IP, FTP, Telnet, HTML, HTTP and web browsers. Because corporate intranets are compatible with internet, selected information can be readily shared with external users. One benefit of using intranet is that different departments of a company having different computer hardware can interact with one another on an intranet. An intranet locates the requested information from internal databases, including inventory and work-in process information, formats the information and passes it from the intranet to the internet and on to the customer. The intranet infrastructure includes a TCP/IP network, web authoring software, web browser hardware and software, web clients, and a firewall server. Intranet can save both time and money. In large and small organizations intranets are always the best way to distribute a wide variety of internal corporate information. Advantages of Intranet 1.
