What is Internet?
The Internet is often known as the World wide web. The Internet is a network built by the cooperative connectivity of millions of computers that are linked together. The Internet is made up of:
- People: The network is used and developed by people.
- Resources: A group of resources that can be accessed through those networks.

What is Intranet?
An intranet is a private network that only employees of a company may access. It's the most restrictive of the three networks. Intranets, like the Internet, employ the HTTP protocol over TCP/IP protocol, web servers, and web clients. Intranets differ from the Internet in that private servers are not accessible to the general public. The users' limitations are implemented through the usage of an internet firewall.
Companies use intranet so that they can store and share important documents and lets teams use private messages and threads to communicate better and collaborate on projects over a secure network. It is only accessible to a small group of people. Intranets are mostly used to offer access to data and programs on networked computers and servers within enterprises and organizations.
What is Extranet?
An extranet is a type of network that allows external users to access an organization's intranet. An extranet is similar to an intranet, except that it is accessed through a Web portal. An intranet is a private network that is only available to members of the same group, corporation, or organization. Extranets are quickly becoming a popular way for business partners to securely communicate information.
