Backbone

November 10, 2007

A backbone is a robust central transmission line (or a collection of transmission lines) that links many smaller local networks via connections known network access points.

It can be a local backbone for a group of office buildings or local area, linking smaller networks to create a wide area network (WAN); or the internet backbone itself, which is made up of superfast, high bandwidth lines (which may be commercial or governmental) that link smaller networks to the internet.

Large ISPs may connect to the internet backbone directly, though smaller ISPs may link to another larger ISP which then links to the backbone.

The fewer links there are between your internet connection and the backbone, the faster your internet connection will be.

WAN – Wide Area Network

August 6, 2007

A WAN, or Wide Area Network, is a network made of up of Local Area Networks (LANs) that are apart geographically. They can be business-owned – for example, a business that has many offices may link its LANs via a WAN using the public phone system, leased lines, or other methods.

However WANs are often public shared-user networks – for example, the biggest WAN is the internet.
