The terms “Internet” and “Intranet” refer to two distinct types of networks, each serving different purposes and audiences.
Typically, The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP)[b] to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
Whereas, the intranet is a computer network for sharing information, easier communication, collaboration tools, operational systems, and other computing services within an organization, usually to the exclusion of access by outsiders. The term is used in contrast to public networks, such as the Internet, but uses the same technology based on the Internet protocol suite.
Let’s see the key differences between the Internet and Intranet:
Audience and Accessibility
Internet: The Internet is a global network that is accessible to anyone with an Internet connection. It is a public network used by individuals, businesses, organizations, and governments worldwide. Information and resources on the Internet are open to the general public.
Intranet: An Intranet is a private network that is restricted to a specific organization, company, or group of users. It is typically used for internal communication, collaboration, and sharing of information among employees or members of the organization. Intranets are not accessible to the public.
Scope
Internet: The Internet encompasses a vast and interconnected network of networks that spans the globe. It includes websites, email systems, online services, and more, connecting billions of devices and users worldwide.
Intranet: An Intranet is a localized network that exists within the confines of a single organization. It may include the organization’s internal websites, file servers, communication tools, and other resources.
Content and Information
Internet: The Internet contains a wide range of publicly accessible content, including websites, blogs, social media, online stores, educational resources, and more. Users can access information on virtually any topic.
Intranet: Intranets are used for sharing internal information, such as company policies, employee directories, project documentation, and collaboration tools. Content on an Intranet is typically restricted to the organization’s employees or authorized members.
Access Control and Security
Internet: Security on the Internet is a shared responsibility between website owners, service providers, and users. Users may need to create accounts, use passwords, and follow security best practices to protect their data and privacy.
Intranet: Intranets are typically more secure because access is restricted to authorized users within the organization. Organizations can implement strict access controls, encryption, and other security measures to protect sensitive information.
Purpose
Internet: The Internet serves a wide variety of purposes, including information dissemination, e-commerce, entertainment, social networking, research, and communication with people around the world.
Intranet: Intranets are designed to facilitate internal communication, collaboration, and information sharing within an organization. They help streamline business processes and improve efficiency.
Scale and Complexity
Internet: The Internet is vast and complex, consisting of a decentralized network of interconnected servers, routers, and data centers. It requires global coordination and infrastructure to function.
Intranet: Intranets are typically smaller in scale and complexity compared to the Internet. They are designed to meet the specific needs of the organization they serve.
The Internet is a global, public network that provides access to a vast array of information and services for users worldwide. In contrast, an Intranet is a private, internal network used by organizations to facilitate communication and collaboration among their members while maintaining security and privacy.
