The Internet and the World Wide Web
Distinct from the Internet, the World Wide Web refers to hypermedia using Hypertext on one part of a link their browser automatically finds the designated information. The development of this innovation is attributed to Tim Berners- Lee. A Very Short History Of The Internet And The Web Forty-five years ago ( October 29, ), the first ARPAnet (later to be known as the Internet) link was (later to be known as the World Wide Web) to his management at CERN. . They start developing the Hypertext Editing System (HES), later used by. Many people don't realize that the World Wide Web and Internet are actually different.

It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the internet. Information that travels over the internet does so via a variety of languages known as protocols. Quick Points about The Internet: It is a global network connecting millions of computers.
The internet is decentralized. Each internet computer is independent. There are a variety of ways to access the internet. There are more than 3. The World Wide Webor simply web, is a way of accessing information over the medium of the internet.
The purpose of the WWW is to allow users to view or make use of more than just text. However, it has become a huge part of many people's lives, enabling them to communicate, work, and play in a global context. The Web is all about relationships, and has made these relationships possible between individuals, groups, and communities where they would not have been otherwise.
This Web is a community without borders, limits, or even rules, and has become a true world of its own. The Web is a giant experiment, a global theory, that has amazingly enough worked pretty well.What is the difference between the World Wide Web and the internet?
Its history illustrates the ways that technological advancement and innovation can move along unintended paths. Originally, the Web and the Internet were created to be part of a military strategy, and not meant for private use.
However, as in many experiments, theories, and plans, this did not actually happen. Instead, the technology got out of military hands and fell into the hands of academics in institutions such as Harvard and Berkeley. The academics made important modifications to it, such as addressing the individual computers from which communications originated and it never stopped growing.
The possibilities of world-wide communication were mind-boggling to people when the Web was just getting started. Nowadays, we think nothing of e-mailing our aunts in Germany and getting an answer back within minutesor seeing the latest streaming video full of up to the minute news.
It is debatable whether a more risk-averse organization lacking the hands-on program management style of ARPA could have produced the same result. It remained in operation untilwhen it was superseded by subsequent networks.
The stage was now set for the Internet, which was first used by scientists, then by academics in many disciplines, and finally by the world at large. Because the NSFNET was to be an internet the beginning of today's Internetspecialized computers called routers were needed to pass traffic between networks at the points where the networks met.
Today, routers are the primary products of multibillion-dollar companies e. Working with ARPA support, Mills improved the protocols used by the routers to communicate the network topology among themselves, a critical function in a large-scale network. An administrative entity, such as a university department, can assign host names as it wishes.
It also has a domain name, issued by the higher-level authority of which it is a part. Thus, a host named xyz in the computer science department at UC-Berkeley would be named xyz. Servers located throughout the Internet provide translation between the host names used by human users and the IP addresses used by the Internet protocols. The name-distribution scheme has allowed the Internet to grow much more rapidly than would be possible with centralized administration.

Jennings left the NSF in During Wolff's tenure, the speed of the backbone, originally 56 kilobits per second, was increased 1,fold, and a large number of academic and regional net- Page Share Cite Suggested Citation: In response to the Connections solicitation, the NSF received innovative proposals from what would become two of the major regional networks: These groups proposed to develop regional networks with a single connection to the NSFNET, instead of connecting each institution independently.
The NSF agreed to provide seed funding for connecting regional networks to the NSFNET, with the expectation that, as a critical mass was reached, the private sector would take over the management and operating costs of the Internet. This decision helped guide the Internet toward self-sufficiency and eventual commercialization Computer Science and Telecommunications Board, Wolff saw that commercial interests had to participate and provide financial support if the network were to continue to expand and evolve into a large, single internet.
Instead of reworking the existing backbone, ANS added a new, privately owned backbone for commercial services in Public access to the Internet expanded rapidly thanks to the ubiquitous nature of the analog telephone network and the availability of modems for connecting computers to this network. Digital transmission became possible throughout the telephone network with the deployment of optical fiber, and the telephone companies leased their broadband digital facilities for connecting routers and regional networks to the developers of the computer network.
In Aprilall commercialization restrictions on the Internet were lifted. Although still primarily used by academics and businesses, the Internet was growing, with the number of hosts reachingThen the invention of the Web catapulted the Internet to mass popularity almost overnight. The idea for the Web was simple: Because the unique names called universal resource locators, or URLs are long, including the DNS name of the host on which they are stored, URLs would be represented as shorter hypertext links in other documents.
When the user of a browser clicks a mouse on a link, the browser retrieves and displays the document named by the URL. Berners-Lee and Cailliau proposed to develop a system of links between different sources of information. Certain parts of a file would be made into nodes, which, when called up, would link the user to other, related files.
Although the Web was originally intended to improve communications within the physics community at CERN, it—like e-mail 20 years earlier—rapidly became the new killer application for the Internet. The idea of hypertext was not new.
One of the first demonstrations of a hypertext system, in which a user could click a mouse on a highlighted word in a document and immediately access a different part of the document or, in fact, another document entirelyoccurred at the Fall Joint Computer Conference in San Francisco.
At this conference, Douglas Engelbart of SRI gave a stunning demonstration of his NLS Engelbart,which provided many of the capabilities of today's Web browsers, albeit limited to a single computer.

Engelbart was awarded the Association for Computing Machinery's A. Turing Award for this work. Although it never became commercially successful, the mouse-driven user interface inspired researchers at Xerox PARC, who were developing personal computing technology.
Widespread use of the Web, which now accounts for the largest volume of Internet traffic, was accelerated by the development in of the Mosaic graphical browser. This innovation, by Marc Andreessen at the NSF-funded National Center for Supercomputer Applications, enabled the use of hyperlinks to video, audio, and graphics, as well as text. More important, it provided an effective interface that allowed users to point-and-click on a menu or fill in a blank to search for information.
Numerous companies now sell Internet products worth billions of dollars.
A multitude of other companies offer hardware and software for Internet based systems. The Internet has also paved the way for a host of services. Other companies, like Amazon. Although estimates of the value of these services vary widely, they all reflect a growing sector of the economy that is wholly dependent on the Internet.
The Web has been likened to the world's largest library—with the books piled in the middle of the floor. Search engines, which are programs that follow the Web's hypertext links and index the material they discover, have improved the organization somewhat but are difficult to use, frequently deluging the user with irrelevant information.
Although developments in computing and networking over the last 40 years have realized some of the potential described by visionaries such as Licklider and Engelbart, the field continues to offer many opportunities for innovation. Lessons from History The development of the Internet demonstrates that federal support for research, applied at the right place and right time, can be extremely effective.

DARPA's support gave visibility to the work of individual researchers on packet switching and resulted in the development of the first large-scale packet-switched network.
Continued support for experimentation led to the development of networking protocols and applications, such as e-mail, that were used on the ARPANET and, subsequently, the Internet. Though a number of companies continue to sell proprietary systems for wide area networking, some of which are based on packet-switched technology, these systems have not achieved the ubiquity of the Internet and are used mainly within private industry.
Research in packet switching evolved in unexpected directions and had unanticipated consequences. It was originally pursued to make more-efficient use of limited computing capabilities and later seen as a means of linking the research and education communities.
