Explanation:

An extranet is a private network that allows partial access to a company's network to partners, services providers, and selected customers. It provides a secure way of information exchange between the business and its stakeholders. An extranet is comparable to a Demilitarized Zone (DMZ) in that it gives authorized parties access to needed services but not the whole network.
