The difference between intranet and internet

The former is an intranet and the latter is the Internet.

The Internet is an international computer network composed of wide area networks, local area networks and stand-alone computers according to certain communication protocols. The Internet refers to the result of connecting two computers or more than two computer terminals, clients, and servers through computer information technology. People can send emails to each other and complete tasks together with friends thousands of miles away. Work and have fun together.

Intranet, also known as enterprise intranet, is a comprehensive network information system established using Internet technology to support internal business processing and information exchange of enterprises and institutions. It usually adopts certain security measures to communicate with the outside of enterprises and institutions. Internet users are isolated from each other, and there are strict regulations on the permissions of internal users to use information.

Compared with the Internet, it can be said that the Internet is a global network, while Intranet is the implementation of Internet technology within an enterprise. It can transfer a large amount of information within an enterprise with very little cost and time. Resources are delivered to everyone efficiently and reasonably. Intranet provides enterprises with a solution that can make full use of communication lines and establish enterprise intranets economically and effectively. By applying intranet, enterprises can effectively carry out financial management, supply chain management, purchase, sale and inventory management, customer relationship management, etc.

In the past, only a few large companies had their own private enterprise networks, but now it is different. With the help of Internet technology, every small and medium-sized enterprise has the opportunity to establish an "intranet" suitable for its own scale. The reason why enterprises pay attention to Intranet is that it is only proprietary to an enterprise and cannot be accessed by external users through the Internet.

To understand Intranet, we must first understand the urgent needs of enterprises for network and information technology.
