:Intranets and extranets may or may not have connections to the Internet. If connected to the Internet, the intranet or extranet is normally protected from being accessed from the Internet without proper authorization. The Internet itself is not considered to be a part of the intranet or extranet, although the Internet may serve as a portal for access to portions of an extranet.
== Classification of computer networks ==
{{Unreferenced|date=December 2006}}
=== By network layer ===
Computer networks may be classified according to the network layer at which they operate according to some basic reference models that are considered to be standards in the industry such as the seven layer [[OSI model|OSI]] reference model and the five layer [[TCP/IP]] model.
=== By scale ===
Computer networks may be classified according to the scale or extent of reach of the network, for example as a [[Personal area network]] (PAN), [[Local area network]] (LAN), [[Campus area network]] (CAN), [[Metropolitan area network]] (MAN), or [[Wide area network]] (WAN).
=== By connection method ===
Computer networks may be classified according to the technology that is used to connect the individual devices in the network such as [[HomePNA]], [[Power line communication]], Ethernet, or [[Wireless LAN]].
=== By functional relationship ===
Computer networks may be classified according to the functional relationships which exist between the elements of the network, for example [[Active Networking]], [[Client-server]] and [[Peer-to-peer]] (workgroup) architectures.
Also, computer networks are used to send data from one to another by the hardrive
=== By network topology ===
Computer networks may be classified according to the [[network topology]] upon which the network is based, such as [[Bus network]], [[Star network]], [[Ring network]], [[Mesh network]], [[Star-bus network]], [[Tree and hypertree networks|Tree or Hierarchical topology network]], etc.

Topology can be arranged in a '''''Geometric Arragement'''''
=== By services provided ===
Computer networks may be classified according to the services which they provide, such as [[Storage area network]]s, [[Server farm]]s, [[Process control network]]s, [[Value-added network]], [[Wireless community network]], etc.
=== By protocol ===
Computer networks may be classified according to the [[communications protocol]] that is being used on the network. See the articles on [[List of network protocol stacks]] and [[List of network protocols]] for more information.
