How does the Internet Work? Coky Fauzi Alfi, SE
What Is the Internet? It is the largest computer system in the world, consisting of thousands of connected networks. A network is a collection of computers, from two to thousands that are linked using special rules called protocols. When computers are connected to the Internet, they are able to communicate and share information.
Terminology: Internet vs. Web The Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections, etc.; the Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs.

How Does the DNS Work? The domain name system (DNS) will take care of the translation of a domain name into an IP address or vice versa. For example, if a user were to type the URL http://www.raritanval.edu, the DNS would translate it into an equivalent IP address of 220.127.116.11.
International Domain Names Domain names outside the United States are, for example, as follows: Australia = au, India = in, Japan = jp, China = cn, United Kingdom = uk, South Africa = za. A domain for a university in Japan could be ftp.meiji.ac.jp, for example, where the domain ac stands for academic (college or university), analogous to edu in the United States, to denote colleges and universities.
