the top-level, or primary, routers and telecommunications circuits interconnecting all of the major computer networks that make up the Internet.
Well actually there are many backbones. These are extremely fast connections(T3 and higher) crisscrossing the globe from one major metropolitan area to another. They are operated by global telecommunication companies and all local ISP(Internet service providers) are connected to these backbone connection through access points.
a super high capacity communications network
a very high-speed, high-capacity data conduit that local or regional networks connect to for long-distance interconnection
The main network connections that make up the Internet Web sites hosted with WebBloom Designs are connected directly to multiple Internet backbone providers including: OC-12 and 1 OC-3 line with Qwest (a leader in reliable and secure broadband Internet based data communications) OC-12 line with AT&T (runs the world's largest, most sophisticated communications network) OC-3 line with UUNET (a global leader in Internet communications solutions) DS-3 line with Time Warner (the world's leading media company) DS-3 line with SBC
An extremely fast network that connects major cities. Most often it utilizes T3 circuits and provides the bandwidth of 45Mbps.
Internet Backbone (or simply the Backbone) is the main high-speed network connection composing the Internet. Backbones are operated by major telecommunications companies like Sprint, MCI, or AT&T.
The network spanning the world that is provided by a handful of national Internet Service Providers (ISPs). They use connections running at approximately 45 megabytes per second linked up at specified interconnection points called national access points. Local ISPs connect to this backbone through routers, so data can be carried through the backbone to its final destination.
This super-fast network spanning the world from one major metropolitan area to another is provided by a handful of national internet service providers (ISPs). These organisations (including Net 99 and Alternet) use connections running at approximately 45 mbps (T3 lines) linked up at specified interconnection points called national access points (which are located in major metropolitan areas). Local ISPs connect to this backbone through routers so that data can be carried though the backbone to its destination. http://www.cnet.com/Resources/ Info/Glossary/Terms/internetbackbone.html
A company that owns large amounts of bandwidth. The bandwidth is leased to ISP's or telephone companies, which allows them to supply consumers with access to the Internet.
The Internet Backbone is the "core" of the Internet. It's a super fast network spanning the globe.
The group of major Internet communication links. ISPs are organisations that connect to the backbone to become part of and have access to the Internet.
The Internet backbone refers to the main 'trunk' connections of the Internet. It is made up of a large collection of interconnected commercial, government, academic and other high-capacity data routes and routers that carry data across the countries, continents and oceans of the world.
