Many people use the terms the Internet and World Wide Web, or just the Web, interchangeably, but the two terms are not synonymous. The World Wide Web is the primary application program that billions of people use on the Internet, and it has changed their lives immeasurably. However, the Internet provides many other services. The Web is a global set of documents, images, and other resources, logically interrelated by hyperlinks and referenced with Uniform Resource Identifiers (URIs). URIs symbolically identify services, servers, and other databases, and the documents and resources that they can provide. Hypertext Transfer Protocol (HTTP) is the main access protocol of the World Wide Web. Web services also use HTTP to allow software systems to communicate in order to share and exchange business logic and data.
The internet originated in 1969, thanks to us military, as a doomsday communication system impervious to nuclear war. by the lead 1980s, it became an important civilian computer network for a variety of academic researchers from professor to physicists and reached outside academic institutions to the borders of the united states. today the internet has users in more than 200 countries. it is a continuous process that expanding rapidly, with thousands of systems adopting internet standard every month in 1993 when commercial providers were permitted to give internet connections to individuals, usage of the network exploded. millions of first-time users came within months, and the new era of computer communication began.
Internet usage has seen tremendous growth. From 2000 to 2009, the number of Internet users globally rose from 394 million to 1.858 billion. By 2010, 22 percent of the world’s population had access to computers with 1 billion Google searches every day, 300 million Internet users reading blogs, and 2 billion videos viewed daily on YouTube. In 2014 the world’s Internet users surpassed 3 billion or 43.6 percent of world population, but two-thirds of the users came from richest countries, with 78.0 percent of Europe countries population using the Internet, followed by 57.4 percent of the Americas.
One cannot survive in the wonderful world of computers if one is not on a website or one’s business card does not have an e-mail ID. a computer network is similar to that of the railway network. it connects numerous computer with one another to disseminate formation. the world wide web or www is a modern marvel that helps find and retrieve information, text, graphic images etc. on sports, films, music, business, politics and every other topic under the sun. At the simple click of a mouse and with the help of software called hypertext transfer protocol one can surf or browse through countless websites gathering information that would otherwise have taken months, years or decades to compile.
The net, as it is popularly called is a global electronic community with over 50000 interconnected computer networks, which means that more than 50 million people are linked together computing what has been aptly termed the information superhighway. the remarkable thing about the internet is that there is no administrator, no coordinating authority, yet starting from a small network setup by us defense department the internet has grown into a truly global supermarket. the internet has added new dimensions to information .it gives each of us the opportunity to be the publisher of our information and views.and as the number of people on the internet multiplies, the opportunities keep growing.
In 2011, researchers estimated the energy used by the Internet to be between 170 and 307 GW, less than two percent of the energy used by humanity. This estimate included the energy needed to build, operate, and periodically replace the estimated 750 million laptops, a billion smartphones, and 100 million servers worldwide as well as the energy that routers, cell towers, optical switches, Wi-Fi transmitters and cloud storage devices use when transmitting Internet traffic.
However, the net had its fair share of problems from the potential danger of electronic crimes and electronic pornography to the virus, from an illegal reproduction of software to the mishandling of electronic systems and illicit into, them from copyright infringement to electronic plagiarism. the internet also suffers from lack of discipline, uniformity and a code of conduct. Internet enthusiast runs the risk of turning into an addict, browsing for hours on end through cyberspace. these problems could be checked through proper regulations that prevent the wrong use of this wonderful gift of science.
