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.

What a typical phishing email may look like
In computing, phishing is an attempt to criminally and fraudulently acquire sensitive information, such as usernames, passwords and credit card details, by masquerading as a trustworthy entity in an electronic communication. eBay, PayPal and online banks are common targets. Phishing is typically carried out by email or instant messaging, and often directs users to enter details at a website, although phone contact has also been used. Phishing is an example of social engineering techniques used to fool users. Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical measures. The first recorded mention of the term "phishing" is on the alt.online-service.America-online Usenet newsgroup on January 2, 1996, although the term may have appeared earlier in the print edition of the hacker magazine 2600. A phishing technique was described in detail as early as 1987, in a paper and presentation delivered to the International HP Users Group, Interex. The term phishing is a variant of fishing, probably influenced by phreaking, and alludes to the use of increasingly sophisticated baits used in the hope of a "catch" of financial information and passwords. The word may also be linked to leetspeak, in which ph is a common substitution for f.

An internet café or cybercafé is a place where one can use a computer with Internet access, most for a fee, usually per hour or minute; sometimes one can have unmetered access with a pass for a day or month, etc. It may serve as a regular café as well, with food and drinks being served.

Selected biography

Mark Zuckerberg in 2005
Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and entrepreneur. As a Harvard College student he founded the online social networking service Facebook with the help of fellow Harvard student and computer science major Andrew McCollum as well as roommates Dustin Moskovitz and Chris Hughes. He now serves as Facebook's CEO. Zuckerberg launched Facebook from his Harvard dorm room on February 4, 2004. It quickly became a success at Harvard and more than two-thirds of the school's students signed up in the first two weeks. Zuckerberg then decided to spread Facebook to other schools and enlisted the help of roommate Dustin Moskovitz. They first spread it to Stanford, Columbia and Yale and then to other Ivy League colleges and schools in the Boston area. By the beginning of the summer, Zuckerberg and Moskovitz had released Facebook at almost 30 schools. Zuckerberg moved to Palo Alto, California with Moskovitz and some friends during the summer of 2004. They leased a small house which served as their first office. Over the summer, Zuckerberg met Peter Thiel who invested in the company. Today, the company has four buildings in downtown Palo Alto.

Our idea of the Internet is that it's an open source, a place where people all over the world can instantly get content. We've tried to use it as a way to develop trust with our fans as much as possible.
