MODULE INTRODUCTION
Computer networks are complex systems that incorporate multiple functions, standards, and proprietary technologies. The Open Systems Interconnection (OSI) model is used to try to simplify some of this complexity. It divides network technologies among seven functional layers. This makes it easier to separate and focus on individual concepts and technologies while retaining an understanding of relationships between functions of technologies placed in other layers.
This module uses the OSI model to give you an overview of the technologies that you will be studying in the rest of the course. You will compare the functions of these layers in the OSI model and apply those concepts to the installation and configuration of a small office/home office network.
You will also learn how to apply a methodology to structure troubleshooting activity, so that you can diagnose and resolve problems efficiently.
MODULE OBJECTIVES
In this lesson, you will do the following:
