World Wide WebThe World Wide Web is often confused with the Internet, but the Internet and the World Wide Web are not exactly the same thing. The hardware and software infrastructure of the Internet provides a global communications system between computers. The Web is one of the services that constitutes a network of interconnected documents linked by hyperlinks and URLs communicated over the Internet. The Internet began in the 1950s when the U.S. Advanced Research Projects Agency (ARPA) began looking for ways to improve the survivability of defense communications networks in the event of a nuclear attack. The result was ARPANET, a defense-oriented computer networking system. In the 1980s, the network expanded to include not only military communications, but also the sharing of scientific data by academic institutions that had been added to the network because of their defense-related research. Eventually, the two aspects of the network were separated for security reasons, with the military portion becoming MILNET, still under the Department of Defense, and the civilian portion becoming NSFNET, under the National Science Foundation. NSFNET was eventually opened for commercial use and links to other developing networks around the world. Tim Berners-Lee is considered the father of the World Wide Web (WWW). While working at the European Particle Physics Laboratory (CERN), he started a project called ENQUIRE. INQUIRE made it possible to create typed links between different information nodes within a single file and across file boundaries in a file system. (Freie Universität Berlin) Thanks to INQUIRE, CERN employees were able to communicate and share documents with each other. Based on his work with ENQUIRE, Berners-Lee was able to develop Hype...... middle of paper ... like images that change when you hover your mouse over them. This can be thought of as being able to think of JavaScript as a set of programs required to run a particular application. Enabling and disabling JavaScript allows you to display the web page with more or less functionality. In some cases, it is possible that without JavaScript you will not be able to view certain aspects of the web page, even if it is not absolutely necessary.ReferencesNSF. (nd).
