The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia in the 1980s, commercialization incorporated its services and technologies into virtually every aspect of modern life.

The Internet has no single centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own policies. The overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of New Seven Wonders. (Full article...)

Opera is a web browser and Internet suite developed by the Opera Software company. Opera handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, IRC online chatting, downloading files via BitTorrent, and reading web feeds. Opera is offered free of charge for personal computers and mobile phones, but for other devices it must be paid for. Features of Opera include high performance, tabbed browsing, page zooming, mouse gestures, and an integrated download manager. Its security features include built-in phishing protection, strong encryption when browsing secure web sites, and the ability to delete private data such as cookies and browsing history by clicking a button. Opera runs on a variety of personal computer operating systems, including Microsoft Windows, Mac OS X, Linux, FreeBSD, and Solaris. Although evaluations of Opera have been largely positive, Opera has had limited success on personal computers. It is currently the fourth most widely used web browser for personal computers, behind Internet Explorer, Mozilla Firefox, and Safari. Opera has a stronger market share, however, on mobile devices such as mobile phones, smartphones, and personal digital assistants.

A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. WLAN utilizes spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area, also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network.

Selected biography

Vannevar Bush
Vannevar Bush (March 11, 1890 – June 30, 1974) was an American engineer and science administrator, known for his work on analog computing, his political role in the development of the atomic bomb, and the idea of the memex—seen as a pioneering concept for the World Wide Web. A leading figure in the development of the military–industrial complex and the military funding of science in the United States, Bush was a prominent policymaker and public intellectual ("the patron saint of American science") during World War II and the ensuing Cold War. Through his public career, Bush was a proponent of democratic technocracy and of the centrality of technological innovation and entrepreneurship for both economic and geopolitical security.

Lawrence Lessig
If the Internet teaches us anything, it is that great value comes from leaving core resources in a commons, where they're free for people to build upon as they see fit.
