Explain about the Intranet hardware and software

Intranets not only provide a secure environment for companies but also provide an excellent working environment that is full of information and resources for the users as well as for decision makers in the company's management. Intranets use a greater part of the system and networking resources. If the data is bulky and consisting of audio or video then they must have broader bandwidth as well as higher throughput for transmission of data. Whereas general messages and documents forming the major part of textual information require less time and transmission speed, the multimedia files require more than 10,000 times the transmission bandwidth. This bottleneck must have been faced by almost everyone accessing the Internet via modem, and the difference it makes when accessing the Internet through ISDN or leased line connectivity. Evidently, the amount of time it can take from the moment a Web page is requested gets loaded with along with all the graphics until the user actually sees the effect on the computer can be considerable.
