• The internet is a global network of interconnected computers and devices that facilitates communication, information sharing, and access to resources across the world. It operates on standard protocols, enabling users to exchange data and interact seamlessly. On the other hand, an extranet extends the functionality of the internet by providing restricted access to selected external users, such as partners, suppliers, or customers, allowing them to securely collaborate, share information, and conduct business transactions within a controlled environment. While the internet connects millions of public networks worldwide, an extranet offers a controlled extension of an organization's network, enabling secure communication and collaboration beyond internal boundaries.
