Virtual Private Network and Network Connections
Network
In information technology, is a network, a certain number of points or nodes connected by communication paths.
Networks can be included with other networks and subnets.
Local Area Network (LAN)
A local area network (LAN) is a group of computers and associated devices that combine a common line or wireless communication.
As a rule, connected devices share the resources of a single processor or server) Within a small geographical area (eg in an office building.
Typically, server applications and stores data, which are common to most users.
A local network can be viewed as only two or three (for example, in a home network) or up to thousands of users (for example in an FDDI network). See also: WAN and MAN
Wide Area Network (WAN)
Wide Area Network (WAN) is ageographically dispersed telecommunications network.
The term distinguishes a broader telecommunication structure from a local area network (LAN).
Wide Area Network can be privately owned or leased, but the term usually connotes the inclusion of public (shared user) networks.
An intermediate form of network in terms of geography is a metropolitan area network (MAN).
Metropolitan Area Network (MAN)
A metropolitan regionNetwork (MAN) is a network that users with computer resources in a geographic area or region's largest indoor compounds include a wide local area network (LAN), but below the surface of a Wide Area Network (WAN) .
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 indicateThe interconnection of several local area networks, bridging lines of spine.
Using the latter is sometimes referred to as a network of campuses.
Backbone
The spine is a transmission line greater than the data gathered from smaller lines that allows you to connect.
Nodes
In a network, a node is a connection point, either a redistribution point or endpoint for data transfers.
In general, a node isprogrammed or designed capacity to recognize and process or forward transmissions to other nodes.
