INTRODUCTION TO THE WWW AND THE INTERNET

Millions of people around the world use the Internet, to search for and retrieve information on all sorts of topics in a wide variety of areas including the arts, business, government, humanities, news, politics and recreation.

People communicate through electronic mail (e-mail), discussion groups, chat channels and other means of informational exchange.

They share information and make commercial and business transactions.

All this activity is possible because tens of thousands of networks are connected to the Internet and exchange information in the same basic ways.

The World Wide Web (WWW) is a part of the Internet. But it’s not a collection of network.

Rather, it is information that is connected or linked together like a web.

You access this information through one interface or tool called a Web browser.

You move from place to place, from site to site on the Web by using a mouse to click on a portion of text, icon or region of a map.

These items are called hyperlinks or links. Each link you select represents a document, an image, a video clip or an audio file somewhere the Internet.

The user doesn't need to know where it is, the browser follows the link.

All sorts of things are available on the WWW. One can use Internet for recreational purposes.

Many TV and radio stations broadcast live on the WWW.

Essentially, if something can be put into digital format and stored in a computer, then it’s available on the WWW.

You can even visit museums, gardens, cities throughout the world, learn foreign languages and meet new friends.

And of course you can play computer games through WWW, competing with partners from other countries and continents.

Just a little bit of exploring the World Wide Web will show you what a much of use and fun it is.
