When the Internet first opened up to commercial markets, the network routing architecture had to be decentralized and eventually new tier 1 Internet Service Providers came to supplant the government sponsored NSFNet. The Internet is basically a global system of computer networks that are interconnected. This interconnected system of computer networks serves billions of users worldwide, proving we do truly live in a globalized world. The Internet is basically a network of networks, which includes public, business, academic, private, and government networks. These networks that comprise the Internet can be on local or global scope and are interconnected by a massive array of optical networking, wireless, and electronic technologies.
The Internet provides so many services. The information resources and services available on the Internet are literally unfathomable. The Internet has completed revolutionised media. Where previously book, newspaper, and print publishing were the main forms of media, these have now been adapted to Web site technology or have changed in form to web feeds and blogs.
