This document discusses using an intranet within a company. It notes that an intranet is separated from the public internet by a firewall, allowing employees to access the internet safely. The intranet contains an email system like regular internet email to enable internal communication. It also has databases, search tools, and groupware to facilitate collaboration. Video conferencing and secure web links allow connections between business locations and subcontractors using the intranet's faster network. Customers can order goods and pay through the company's website on the intranet.
