Internet Vs Intranet Vs Extranet: What’s the Difference?

When you’re looking to connect with other companies or individuals on the internet, you use the internet. When you want to connect with a smaller group of people within your company or organization, you use an intranet. And when you want to connect with a much larger group of people outside your company or organization, you use an extranet.

What’s the difference between these three types of networks? The answer is: it depends.

An internet network connects many different organizations and individuals. An intranet connects one or more organizations but not many different individuals. And an extranet connects many different organizations and individual.

So which type of network is right for your business? It depends on your needs and goals.

What is an Intranet?

An intranet is a private network that links together individual workstations within an organization. Intranet usage typically occurs within businesses where employees need to share information, collaborate on projects, and access resources that are not available to the public.
An extranet is a public network that allows participating companies to share information and resources with each other. Extranet usage typically occurs when companies need to collaborate on projects with other companies or when they want to sell products or services to customers outside of their own company.

What is an Internet?

An Internet is a global system of interconnected computer networks that use the internet protocol suite to link devices worldwide. It is a network of networks, which uses the TCP/IP protocol suite to communicate with other networks. The word “Internet” was first coined in 1969 by Vinton Cerf and Robert Kahn, and it was originally used to describe the ARPANET, a research network. The first public internet usage was on 4 August 1969 when University of California at Los Angeles (UCLA) researchers accessed the system from their workstations.
Intranet refers to a closed system within a company or organization where employees have access to restricted resources. Intranet usage began in the early 1990s as companies realized the benefits of having a secure internal network for sharing information. Today, many companies have developed intranets as an extension of their websites. Extranet is an open system that enables third-party interactions beyond those allowed on the intranet. Extranet usage began in the mid-1990s as companies realized the benefits of exposing their products and services to a wider audience. Today, many companies use extranets to share information with customers and partners outside their organization.

What is an Extranet?

An extranet is a private network that connects companies or organizations with other companies or organizations outside their own organization. It differs from an intranet, which is a private network within one organization. Extranets can be used for sharing information between different departments or divisions within an organization, as well as with customers and suppliers.

Difference between the Three Types of Networks

Internet: The most common type of network is the Internet. This network connects computers together and allows users to access the World Wide Web. Users can also use the Internet to send and receive emails, instant messages, and upload files.

Intranet: An intranet is a type of network that is used within a company or organization. This type of network is usually smaller than the Internet and allows employees to share files and folders. Intranets are also commonly used to connect multiple departments within an organization.

Extranet: An extranet is a type of network that is used between companies. This type of network is often more advanced than an intranet and allows companies to share information such as customer data, financial information, and product information.

Benefits of using an Intranet over the Internet

When it comes to being productive and getting work done, there are a few key differences between the Internet and an Intranet. Here’s a look at some of the benefits of using an Intranet over the Internet:

-An Intranet is private and secure. Data is not exposed to the public or outside sources, which means that your information is protected. You can also communicate with colleagues and clients privately, which can be helpful for sensitive or confidential work.

-Inter-company communication is easier on an Intranet. With a private network, companies can easily share files, project updates, and other important information without having to worry about anyone else seeing it. This can save you time and money in the long run because you won’t have to go through unnecessary exchanges or negotiations with other organizations.

-An Intranet offers more collaboration options than the Internet. For example, you can create group projects and share resources more easily on an Intranet than on the Internet. This can help you work more effectively as a team, which is important for businesses that need to collaborate on complex projects.

Benefits of using an Internet over an Intranet

If your business depends on communicating with customers and employees over a wired or wireless network, you may want to consider using an Internet instead of an intranet. Here are some key reasons:

-Speed: The speed of an Internet connection is typically many times faster than a connection on an intranet.
-Accessibility: Anyone with access to the Internet can view your website. An intranet is accessible only to employees who have access to the network.
-Cost: An Internet connection costs less than a connection to an intranet.
-Security: Your website is more likely to be protected by firewalls on the Internet than on an intranet.

Why use them?

Intranet and extranet are different types of the internet. Intranet is a network that connects business or organizational units within a company. Extranet is a network that connects businesses or organizations with each other.

The main difference between intranet and extranet is that intranet is used within one organization, while extranet is used between organizations. Intranet provides employees with a private space to share information, ideas and work together cooperatively. Extranet provides businesses with an opportunity to connect with other businesses and obtain valuable resources and knowledge.

Intranets can provide a secure way for companies to share sensitive information, while also providing companies with the ability to exchange ideas and collaborate on projects. Extranets can help businesses find new customers and suppliers, as well as learn about new technologies and trends.


In today’s world, it seems like everyone and their dog is using the internet. But what is the internet, and what are the different types of networks it can be found on? In this article, we will discuss the three main types of networks – intranet, extranet, and the internet – and explain their differences. Hopefully this will help you to make an informed decision about which network is best for your business.
