INTERNET

InternetThe Internet start to be more important in our life each day which is it also one of the newest invention that change a lot of our view on media and communication and other things .The internet is the most powerful, global data communications system making it the greatest invention of science because of its wide range of benefits and uses in the world today. The Internet has revolutionized the computer and communications world like nothing before. The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. The Internet is at once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location. The Internet represents one of the most successful examples of the benefits of sustained investment and commitment to research and development of information infrastructure.

The Internet originated in the late 1960s when the United States Defense Department developed ARPAnet (Advanced Research Projects Agency network), an experimental network of computers designed to withstand partial outages such as a bomb attack. The agency sought to create a web of computers that could continue to communicate with each other, even if some of the computers were disabled. In the mid-1980s, when desktop computer workstations became increasingly popular, organizations wanted to connect their local area networks (LANs) to ARPAnet. If computers could link together and share resources, everyone would benefit.

To help speed the connections, the National Science Foundation (NSF) established five super computing centers in 1986, creating the NSFnet backbone. In 1987, the NSF signed a cooperative agreement to manage the NSFnet backbone with Merit Network, Inc., and by 1990, ARPAnet had been phased out. NSFnet continued to grow, and more and more countries around the world connected to this Internet backbone.

1991 was a big year for the Internet: The National Research and Education Network (NREN) was founded and the World Wide Web was released. The Internet is still dominated by scientists and other academics, but begins to attract public interest. With the release of the Mosaic Web browser in 1993 and Netscape in 1994, interest in and use of the World Wide Web exploded. More and more communities become wired, enabling direct connections to the Internet. In 1995, the U.S. federal government relinquished its management role in the Internet and NSFnet reverted back to being a research network. Interconnected network providers are strong enough now to support U.S. backbone traffic on the Internet. However, the presidential administration encourages continued development of the U.S. backbone of the Internet, also knows as the National Information Infrastructure (NII)-- and, most commonly, as the "Information Superhighway".

Similar to any other invention, the internet carries a number of advantages and disadvantages. Nevertheless, the advantages of the internet are more than its disadvantages. Talking about the advantages of internet, are as follows:

The biggest benefit offered by the internet is information. It functions as a valuable resource of information. You can find any type of information on any subject with the help of the search engines like yahoo and Google. The primary goal of the internet is communication. It has extremely done well in this field, however the development process is still going on to make it more dependable and quick. By sending an e-mail we can contact a person who is physically present thousands miles away within the fraction of a second’s time. Internet functions as a popular medium of entertainment. A wide variety of entertainment including video games, music, movies, chat room, news and others can be accessed through the internet. Sales have grown rapidly over the internet. E-commerce has become a fantastic option through which we can hop anything. Internet helps of community and forum formation. Here a number of people can participate in different types of debates and discussions express their views and gather valuable knowledge. A variety of services are offered via internet for example job searching, online banking, buying books, hotel reservations and consultation services etc.
