discuss the architecture of Web

What event will trigger the application of the learning?	What degree of success will learner accomplish?
When the learners needs to advise on appropriateness and design of the architecture of Intranet, Corporate portal, and Extranet. When the learner needs to advice on appropriateness of design of the architecture of a Web-based system for doing business on-line.	Learners will be able to explain the functionality of Intranet, corporate portal, and Extranet, discuss the technologies that enable these platforms, and compare and contrast these strategies in terms of both functionality and architecture. Learner will be able to explain the architecture of the Internet and the Web.

Learning Objectives in the 'Mandatory Objectives' column refer to the bare minimum you need to learn to pass. It is essential that this learning is undertaken.
