links (data connections).
extranet - Answer-An extranet is a website that allows controlled access to partners,
vendors and suppliers or an authorized set of customers - normally to a subset of the

that it provides access to needed services for authorized parties, without granting
access to an organization's entire network.
intranet - Answer-An intranet is a private network accessible only to an organization's

leased telecommunication circuits, while the media for LANs are locally managed.
mainframe - Answer-Mainframe computers (colloquially referred to as "big iron") are
computers used primarily by large organizations for critical applications, bulk data
processing such as census, industry and consumer statistics, enterprise resource
planning and transaction processing.

computer network larger than a local area network, covering an area of a few city blocks
to the area of an entire city, possibly also including the surrounding areas.

computer networking devices, are physical devices which are required for
