Even though the Internet is a global network, in many ways it resembles a small town, with similar services. Let's say you want to send or receive mail. The Internet has electronic post offices. There are online libraries with millions of books and periodicals you can use any time of the day or night. Chat rooms are the Internet equivalent of 24-hour coffee shops, with people eager to gab anytime you want. With the explosive growth of the World Wide Web, you can shop, order a pizza, preview a movie, and listen to radio stations from around the world. All of these represent different ways of using the Internet.
In the real world you can travel to different places over the same network of roads using different modes of transportation. You might use a car for one purpose and a truck for something else. Getting around on the Internet works much the same way.
To understand the Internet, it is helpful to realize that many different kinds of communication go on at the same time. You use different software programs to accomplish different tasks: for instance, a web browser to access shopping sites and an e-mail program to send and receive messages.
Some programs, such as Microsoft Internet Explorer, contain more than one kind of program. For instance, Explorer has a web browser a newsreader and a media player. (In later articles, we will explain what each of these programs do.) You can also use more specialized and sophisticated software, such as RealPlayer, a stand-alone media player or combine different software programs together into a system that works for you.
Now that you have an idea of some of the resources available on the Internet, explore how the Internet impacted modern life. The BBC Online has some fascinating case histories.
