Internet
The Internet is a global network of interconnected smaller computer networks. Data is transmitted in small packets using the Internet Protocol (IP) where they are then reassembled. It originated in the work of DARPA, a research division of the US Army.
The Internet is sometimes also known as Cyberspace. Sometimes it is inaccurately referred to as the Web or the World Wide Web, because the Web is only one of numerous protocols that operate on the Internet.
The common protocol used to access websites (including this one) is the Hyper-Text Transfer Protocol (HTTP). The creator of this is Sir Tim Berners-Lee, who recently in an online magazine article claimed that given the opportunity, he wouldn't use the HTTP format for websites.
Berners-Lee is currently the director of the W3 Consortium (World Wide Web Consortium).
