CHAPTER 2: The Internet, The Web and Electric Commerce

Internet is referred as Information Superhighway because it connects million of people across the globe. Internet was launched in 1969. The Internet is named after the Internet Protocol, the standard communications protocol used by every computer on the Internet. The Internet can powerfully leverage your ability to find, manage, and share information. Never before in human history has such a valuable resource been available to so many people at such little cost. The Web provides an easy to use, intuitive interface to connect to the Internet and is used by millions of people everyday. Internet uses commonly for communicating, online shopping, searching, entertainment, education and so on. 

How does the Internet work? The Internet workings include a technical design and a management structure. The management structure consists of a generally democratic collection of loosely-coupled organizations and working groups with mostly non-overlapping responsibilities. The technical design is founded on a complex, interlocking set of hierarchical tree-like structures, like Internet Protocol addresses and domain names, mixed with networked structures like packet switching and routing protocols, all tied together with millions of lines of sophisticated software that continues to get better all the time. So far this combination of management and technical structures has worked well, providing the reliable, powerful communication platform on which the rest of the complexity of the Internet is built.

A web browser  is a  software application  for retrieving, presenting, and traversing information resources on the World Wide Web.  An information resource is identified by a URLs and may be a web page, image, video, or other piece of content.

All major web browsers allow the user to open multiple information resources at the same time, either in different browser windows or in different tabs of the same window. Major browsers also include pop-up blockers to prevent unwanted windows from "popping up" without the user's consent.
