Internet, intranet, and extranet are all networks that allow communication and sharing of information among users, but they differ in terms of their accessibility, security, and purpose. Here are the key differences between them:
Internet: The internet is a global network of interconnected devices and computers that use standard communication protocols to exchange information. It is a public network that allows users to access and share information from anywhere in the world.
Intranet: An intranet is a private network that is accessible only to the employees of an organization. It is used to share internal information and resources such as documents, databases, and communication tools. Intranets are typically protected by firewalls and other security measures to prevent unauthorized access.
Extranet: An extranet is a private network that is accessible to authorized users outside of an organization, such as partners, suppliers, and customers. It is used to share information and collaborate on projects with external stakeholders. Extranets are also protected by security measures to ensure that only authorized users can access the network.
In summary, the internet is a public network, while intranets and extranets are private networks that provide secure communication and collaboration among employees and external stakeholders respectively
