Virtual Private Network and Network Connections

Network

In information technology, is a network, a number of points or nodes connected by communication paths.

Networks can be included with other networks and subnetworks.

Local Area Network (LAN)

A local area network (LAN) is a group of computers and associated devices that combine a common line or wireless communications.

As a rule, connected devices share the resources of a single processor or server within a small geographic area (forfor example) within an office building.

Typically, the server applications and data stores, which are jointly shared by multiple computer users.

A local area network) can than just two or three users (for example, in a home network) or up to thousands of users (eg in an FDDI network. See also: WAN and MAN

Wide Area Network (WAN)

Wide Area Network (WAN) is a geographically dispersed telecommunications network.

The term distinguishes a broaderTelecommunication structure from a local area network (LAN).

Wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks.

An intermediate form of the network in terms of geography is a metropolitan area network (MAN).

Metropolitan Area Network (MAN)

A Metropolitan Area Network (MAN) is a network that users with computer resources in a geographic area or region larger than the compounds to theeven a large local area network (LAN) but smaller than the area of a Wide Area Network (WAN) covered.

The concept is to make the interconnection of networks in a city with a larger network used (which then also offer efficient connection to a Wide Area Network).

It is also used to ensure the interconnection of several local area networks by bridging them with backbone lines mean.

The latter use is sometimes referred to as a campus network.

NetworkBackbone




A backbone is a larger transmission line that the data gathered from smaller lines that helps connect.

Nodes

In a network, a node is a connection point, either a redistribution point or endpoint for data transfers.

In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.
