Internet
Almost everyone with or without a computer is aware of the latest technological revolution destined to change forever the way in which humans communicate, namely, the Information Superhighway, best exemplified by the ubiquitous Internet. Already, millions of people around the world are linked by computer simply by having a modem and an address on the "Net", in much the same way that owning a telephone links us to almost anyone who pays a phone bill. In fact, since the computer connections are made via the phone line, the Internet can be envisaged as a network of visual telephone links.
The World Wide Web, an enormous collection of Internet addresses or sites, all of which can be accessed for information, has been mainly responsible for the increase in interest in the Internet in the 1990s. Before the World Wide Web, the "Net" was comparable to an integrated collection of computerized typewriters, but the introduction of the "Web" in 1990 allowed not only text links to be made but also graphs, images and even video.
A Web site consists of a "home page", the first screen of a particular site on the computer to which you are connected, from where access can be headed to other subject related "pages" (or screens)at the site and on thousands of other computers all over the world. This is achieved by a process called "hypertext". By clicking with a mouse device on various parts of the screen, a person connected to the "Net" can go traveling, or "surfing" through a web of pages to locate whatever information required.
Anyone can set up a site, promoting your club, your institution, your company's products or simply yourself. And what is more, information on the Internet is not owned or controlled by any organization. It is, perhaps, true to say that no one and therefore everyone owns the "Net". Because of the relative freedom of access to information, the Internet has often been criticized by the media as a potentially hazardous tool in the hands of young computer users. This perception has proved to be largely false however, and the vast majority of users both young and old get connected with the Internet for the dual purposes for which it was intended--discovery and delight.
