Answers
Internet
Internet is a clustered system of interrelated computer networks that uses a standard Internet protocol (IP) or transmission control protocol (TCP) network.
It is a global network of millions of private, public and organizational network. It carries a massive range of informational resources and data in form of HTTP (Hypertext Markup language) documents and applications through World Wide Web (WWW).
Intranet
Intranet is a computer network system in which a specific organizational systems share information, computing services and operational systems with each other by using an Internet technology.
This term basically refers to the network of a specific organization. You can also says it a private network.
The benefits of Intranet is that low development and maintenance cost arises on this setup. It is also a means of friendly environment and speedily sharing of secret information on time.
It although utilizes the technologies of wide area networks and local area networks but still the employees of an organisation remain its only users. Intranet started to grow across the world after the internet when some large organisations started to develop their own internal internet system that was later on named as an intranet.
The main aim of the intranet is to ensure the secure collaboration, communication and team working in any organisation.
Extranet
The term Extranet is linked with Intranet. Extranet is a kind of computer network that allows the outside users to access the Intranet of organization.
This network system is basically used for business to business (B2B) purposes. This system basically allows the outside users of an organization, like partners, suppliers, vendors and other stakeholders to remain in touch with the activities of organization.
When the usage of the internet remains restricted to the internal environment of an organisation only it is called as intranet but when the customers and other outsiders like the stakeholders of an organisation also join this system then this system becomes the extranet.
The users in case of extranet also remain very limited but in this system, there remains the some involvement of the outsiders that are directly connected with any business.
After setting the extranet, the users can then send private messages by using the public network system through the most enhanced encryption and security technologies.
The information in all way is accessible through the intranet of an organization. If intranet is derivate from the internet then extranet is derivate from the intranet.
