Lesson 1

Introduction to the Web Interaction Model

Any communication can be separated into the message (the content of the communication) and the medium (plural of media, including such items as a newspaper, a compact disc, word of mouth, or a Web site). In the previous module, you were introduced to the message elements of a Web site, the first three layers of the Web Interaction Model:
  1. Signs and Metaphors, where the user interprets the message of a Web site;
  2. Information Architecture, the architecture that structures the navigation through the message; and
  3. Software, applications that enable the design and support the storage of files necessary to the site.

This module discusses the Web Interaction Model as a framework for understanding the two remaining layers of the model: Networks and the Internet, and Hardware.
These layers are the media over which the message is sent and the physical components required to send and store the message and associated data.
You will also learn about some of the protocols by which networks communicate, as well as how businesses are using the Internet to leverage the power of Web-based applications.


Module objectives

By the end of this module, you will be able to:
  1. Explain the setup and purpose of the Internet, intranet, and extranet.
  2. Explain TCP, IP, HTTP, and FTP protocols
  3. Explain how Web resources are transmitted across the Internet
  4. Describe components of the hardware layer
  5. Use the Web Interaction Model to explain how resources are requested and received via the Web
  6. Explain how the Web-based business applications are supported by the Web Interaction Model
In the next lesson, you will learn the distinctions between the Internet, intranets, and extranets.
