Internet vs Extranet vs Intranet

  • Internet

    This is a globally-connected network of computers that enables the public to share information and communicate with each other.

  • Extranet

    This is the area where users from some organisations are given access to the organisation information. Example of these users are customers and vendors.

  • Intranet / Local Area Network (LAN)

    This is a local or restricted network that enables employees to store, organize, and share information within an organization.

    LAN is a local network whereas Intranet doesn't have to be local, it can be a network within a company with 3 different offices which are all inter-linked with a WAN (Wide Area Network).
