Nowadays we can see many people know how to surf the internet...even the children know how to explore the online world such as through facebook, myspace and friendster..but do they know what is the internet actually?
Formally, the Internet is a global system of interconnected computer networks that use the standardized Internet Protocol Suite to serve billions of users worldwide. It is a network of networks that consists 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. Voice over Internet Protocol (VoIP) applications allow person-to-person communication via voice and video.
The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. In addition it supports popular services such as online chat, file transfer and file sharing, gaming, social networking, publishing, video on demand, and teleconferencing and telecommunications.
The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks. The period of civilian funding of a new U.S. backbone by the National Science Foundation spawned worldwide participation in the development of new networking technologies and led to the commercialization of an international network in the mid 1990s, and resulted in the following popularization of countless applications in virtually every aspect of modern human life. As of 2009, an estimated quarter of Earth's population uses the services of the Internet.
The Internet transmits data from one computer (host) to another. The Internet can be connected in the 3 simple steps:
The Internet allows computer us to remotely access other computers and information stores easily, wherever we may be across the world. We may do this with or without the use of security, authentication and encryption technologies, depending on the requirements. This is encouraging new ways of working from home, collaboration and information sharing in many industries.
Using the Web, it is also easier than ever before for individuals and organizations to publish ideas and information to a potentially large audience. Publishing a web page, a blog, or building a website involves little initial cost and many cost-free services are available. Publishing and maintaining large, professional web sites with attractive, diverse and up-to-date information is still a difficult and expensive proposition, however. Many individuals and some companies and groups use web logs or blogs, which are largely used as easily updatable online diaries. Some commercial organizations encourage staff to communicate advice in their areas of specialization in the hope that visitors will be impressed by the expert knowledge and free information, and be attracted to the corporation as a result.
