Virtual Private Network (VPN)

Virtual Private Network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (eg Internet), rather than physical cables. Data protocols layer of virtual network are said to tunnel through the larger network when this is appropriate. A common application is secure communications through the public Internet, VPN, but no specific security features such as authentication or content encryption. Virtual private networks, could be used for traffic of different user groups to separate the main network with strong security.

A VPN is the best performance, effort, or may have a service level agreement (SLA) between the VPN client and VPN service provider. Usually, VPN has a topology more complex than point to point.

A VPN allows computer users to go to edit the IP address space, other than the actual computer that connects to the Internet.

Internetwork

Work is an Internet connection between two or more different networks or network segments via a common technology for routing. The result is called Internetwork (often shortened to internet). Two or more networks or network segments connected using devices that operate at layer 3 (layer “network”) of the Open Society Institute, the basic model, such as a router. Any connection between or among public, private, commercial, industrial or governmental networks may be defined as an Internetwork.

In current practice, interconnected networks using Internet Protocol. There are at least three versions of the Internet works, depending on who administers and who participates in them:

* Intranet
* Extranet
* Internet

Intranets and extranets may or may not have an Internet connection. When connected to the Internet, intranet or extranet is normally protected against access from the Internet without proper authorization. The Internet is not considered part of an intranet or extranet, although it may serve as a portal for access to parts of the extranet.
