This document defines and compares the Internet, intranets, and extranets. The Internet is a global network that connects devices worldwide using TCP/IP protocols. An intranet is a private network within an organization that shares resources via the Internet, while an extranet allows selected partners external access. Intranets provide internal communications and operations centralized through a dashboard. Extranets enhance business-to-business relationships by linking an organization's intranet to partners.

accentuates what you would do anyway. If you want
to be a loner, you can be more alone. If you want to
connect, it makes it easier to connect.
