The Internet is the largest computer network in the world. Like any other computer network, it consists of a collection of computers, a collection of physical links between the computers, and rules or protocols governing how the data exchanges will take place between the computers.

In simple terms, the Internet is nothing more than an enormous global network. As you will discover, most computers on the Internet are part of smaller networks that serve governments, universities or companies. Today, corporations and individuals use the Internet for many purposes including marketing and commerce. It provides a means of reaching tremendous numbers of prospects at an unbelievably low cost. The Internet is the medium that is attracting all types of businesses in record numbers.
