The Internet is a global communications network connecting millions of computers in most countries around the world. No single organisation owns the Internet, and within each country regional and national networks are linked globally by satellite and fibre optic cable. Telstra Internet manages the Internet links within Australia, and international gateways to the USA, Asia, and New Zealand.

The World Wide Web uses hypertext links to connect to material on computers around the world.
