S ECTION 1: G ETTING T O K NOW C OMPUTERS T ODAY A computer is simply a machine that is programmed to follow instructions. They can be used to calculate personal finances, make animated films, order airline tickets, develop blueprints for a building, and many more things you can do……. Your computer depends on the hardware and software that your computer has.

S ECTION 2: T HE I NTERNET AND T HE W ORLD W IDE W EB 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.

T HE I NTERNET 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.
