The Internet is a global system of interconnected computer networks, consisting of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet appears to its users as a single worldwide network accessible to the general public. The protocol that makes it possible to use the millions of networks composing the Internet as if they were one network is a special type of packet switching known as IP or The Internet Protocol.

A computer that connects to the Internet can access information from a vast number of servers and other computers. An Internet connection also allows the computer to send information through the network; that information may be saved and ultimately accessed by a variety of servers and other computers. Much of the information widely accessible through use of the Internet consists of the interlinked hypertext documents and other resources of the World Wide Web (WWW). Web users typically send and receive information using a web browser. Other software for interacting with computer networks includes specialized programs for electronic mail, online chat, file transfer and file sharing.

Information is moved around the Internet by packet switching using the standardized Internet Protocol Suite (TCP/IP)which defines how packets are moving in any platform especially the transport layer. The Internet Protocol Suite consists of several layers of protocols. The lowest layer (the link layer) deals with protocols that transmit data over specific technologies, such as Ethernet or Wi-Fi. The highest layer (the application layer) supports specific applications,such as e-mail and file transfer. In between are the Internet layer, which provides for transmitting packets over any conceivable technology, and the transport layer, which provides for various services such as reliable delivery of packets or real-time streaming of packets. atlast internet accessible to the general public.

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.

Webcams are small cameras, (usually, though not always, video cameras) whose images can be accessed using the World Wide Web, instant messaging, or a PC video conferencing application. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion.

Selected biography

Vint Cerf in 2007
Vinton Gray Cerf (born June 23, 1943) is an American computer scientist who is the "person most often called 'the father of the Internet'." His contributions have been recognized repeatedly, with honorary degrees and awards that include the National Medal of Technology, the Turing Award, and the Presidential Medal of Freedom. Cerf's first job after getting his B.S. in mathematics from Stanford University was at IBM, where he worked for less than two years as a systems engineer supporting QUIKTRAN. He left IBM to become a principal programmer at UCLA; he then became an assistant professor at Stanford University where he co-designed the Department of Defense TCP/IP protocol suite with Robert E. Kahn. Cerf joined the board of the Internet Corporation for Assigned Names and Numbers (ICANN) in 1999, and is serving a term until the end of 2007; he previously served as the ICANN Chair.

Like anything else, you can use the internet for good or ill. You can get out of it what you want to. There's no evil about it. The way I see it, it's a liberation.
