Many people use the terms Internet and World Wide Web, or just the Web, interchangeably, but the two terms are not synonymous. The World Wide Web is only one of hundreds of services used on the Internet. 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.
World Wide Web browser software, such as Microsoft’s Internet Explorer, Mozilla Firefox, Opera, Apple’s Safari, and Google Chrome, lets users navigate from one web page to another via hyperlinks embedded in the documents. These documents may also contain any combination of computer data, including graphics, sounds, text, video, multimedia and interactive content that runs while the user is interacting with the page. Client-side software can include animations, games, office applications and scientific demonstrations. Through keyword-driven Internet research using search engines like Yahoo! and Google, users worldwide have easy, instant access to a vast and diverse amount of online information. Compared to printed media, books, encyclopedias and traditional libraries, the World Wide Web has enabled the decentralization of information on a large scale.
Online journalism is reporting and other journalism produced or distributed via the Internet. The Internet has allowed the formal and informal publication of news stories through mainstream media outlets as well as blogs and other self-published news stories. Journalists working on the Internet have been referred to as J-Bloggers, a term coined by Australian Media Academic Dr Nicola Goc to describe journalists who [blog] and [blog]gers who produce journalism. “J-Bloggers: Internet bloggers acting in the role of journalists disseminating newsworthy information, who subscribe to the journalistic ideals of an obligation to the truth and the public’s right to know”.
Broadcasting is the distribution of audio and video signals (programs) to a number of recipients that belong to a large group. This group may be the public in general, or a relatively large audience within the public. Thus, an Internet channel may distribute text or music worldwide, while a public address system in (for example) a workplace may broadcast very limited ad hoc soundbites to a small population within its range.
