Internet, Intranet& Extranet Overview

Internet, intranet, and extranet are three terms used to describe different types of networks that connect computers and other devices together.


1. Internet: The internet is a global network of interconnected computers and servers that allows users to share information and communicate with each other. It is a public network, meaning that anyone with an internet connection can access it. The internet is typically accessed through web browsers, email clients, and other software applications.


2. Intranet: An intranet is a private network that is used by a specific organization, such as a business, government agency, or educational institution. An intranet is typically accessible only to employees or members of the organization, and it is used for sharing information and resources within the organization. Intranets are often secured with firewalls and other security measures to prevent unauthorized access.


3. Extranet: An extranet is a network that connects an organization with its external partners, such as suppliers, vendors, and customers. An extranet is similar to an intranet in that it is a private network, but it allows external partners to access certain parts of the organization's network. Extranets are typically used for collaboration, supply chain management, and other business functions that require close coordination with external partners.


In summary, the internet is a public network that connects computers and servers around the world, while an intranet is a private network used by a specific organization. An extranet is a network that connects an organization with its external partners, allowing for collaboration and coordination.
