SECTION 2:THE INTERNET AND THE WORLD WIDE WEB

In this section, you will learn about the biggest thing to hit our culture since

television…. the Internet. People 25 years ago could not imagine much

of what we take for granted every day, such as cell phones, global positioning devices, digital cameras, the list goes on and on.

THE INTERNET The Internet is millions of computers all around the world

connected together. No one person, company, or entity owns or controls the

Internet. There is no one in charge! Much of the hardware components that make up the Internet are owned or shared by thousands of private and

public organizations. There are supercomputers called NAPs (Network Access

Points), that serve as major hubs. Your personal computer at your house is an example of a

computer that primarily requests data, called a Client. Computers that provide data are called Servers, since they

“Serve” data to other computers. Computers that help information travel across the Internet

are called Routers. Every time data takes a turn on the Internet, a Router is there to send it in the right direction.
