Thus the Internet is nothing more than a network of networks. These networks connect computers using a wide variety of technologies, including conventional and high-speed telephone lines, fibre-optic cables, microwave links, wireless technologies and satellite communications.
The networks are connected using routers. A router is a specialised computer that directs traffic on the Internet. As the Internet consists of hundreds of thousands of smaller networks linked together, the use of routers is absolutely necessary.
The Internet backbones are a collection of networks that link extremely powerful super-computers. The backbones are made up of fibre optic trunk lines (aka OC for optical carrier). The fastest OCs can transit 2.488 gigabits per second!
In order to connect the various lower order networks which make up the vastness of the Internet, various types of equipment are used. These include bridges, gateways and hubs.
Gateways are similar to bridges. However they also translate data from one type of LAN to another. For example, they can translate data from a UNIX system so that it is intelligible on an Intel-based system.
In addition, the Internet Society, which was founded in 1992 as a non-profit association, facilitates the open development of the standards, protocols, administration, and technical infrastructure of the Internet… ensuring the smooth evolution and operation of the network of networks.
