Extranet, on the other hand, is an extension of the intranet where the system is protected even more and is only accessible to particular people. Most organizations such as a company or universities have an intranet for their purposes and can be viewed on the premises. An extranet is used by different businesses for sharing private information with particular people while the Internet is used for general purposes. They have varying levels of ease. The Internet does not require any passwords, but the extranet always requires login and password information.The mixture of these two is referred to as an extranet. An intranet can be called a private internet while an extranet can be called a private intranet.

What is Internet

The Internet is a global network of computing systems that are connected to each other and help in providing information to everyone who has access. When a web address is entered, the internet makes use of an internet protocol address which tells the exact location of the computer, and where it is present.

From there it gets the information from sets of devices known as the webserver which can have a domain name and an address which is then displayed with the help of a browser. It has a basic level of security and does not have firewalls to protect it.

There is no requirement of a password to use it and people anywhere, who have the availability of a computer can get all the information that they require.

What is Extranet

An Extranet is best explained as a network that depends on the internet but is restricted to specific users. It is more accurate than intranet in a way that only a few people instead of a particular place can get access. It is protected by a firewall and if the intranet is accessed from the internet to send or receive the information it becomes an extranet.

It is mostly used by businesses and companies who have to share sensitive data with each other. The firewall is used to switch between the internet and intranet and lets only the people who can log in with the help of passwords or by internet protocol addresses. It can be used by individuals or a group of folks depending on the level of requirement.
