An intranet is a network that operates only internally within an organization.
As such, only those individuals who work within the organization have access to its intranet. Quite often the intranet is used to communicate among employees and as means for management to disseminate information quickly. For example, both Wal-Mart and FedEx have intranets that provide employees at all locations with up-to-date information on new procedures, changes in company policies, performance measurements, and recognition
of outstanding employees. The FedEx intranet even includes its own television station that broadcasts company-related news 24 hours a day.
