There are many different ways to understand how the Web works. Because there is great variety in the complexity of technologies, various models have been developed as tools for understanding and discussing the Web.
This course introduces the Web Interaction Model, a robust tool for conceptualizing how the full range of components work together on the Web, from the design elements, including how a Web site creates a particular look and feel, to the more technical elements, such as software and hardware considerations.

By the end of this module, you will be able to:

1. Describe how Web technologies have changed the ways people use and obtain information
2. Describe the components that make up the various Web models
3. Explain the function of the Web Interaction Model
4. Describe how the Web Interaction Model relates to other models

In the next lesson, you will learn why models are necessary and gain an overview of how the Internet has affected the way we use information.
