II. OBJECTIVES


Students will be introduced to a practical extension of the math skills previously acquired in other classes. The math skills be be used to convert basic electronic measurements into power consumption. This information will then be used to perform basic maintenance repair and/or replacement tasks.


The students will test various components for their workability and function. They will recognize not only components that fail to work completely, but they will evaluate those components for optimal system performance.


The information contained within this lesson corresponds directly to PC Technical tasks. This information will complement other lesson plans, allowing the student to exhibit confidence in the troubleshooting methods to follow.

Chapter 2 Review Questions



IV. RESOURCES REQUIRED:



Tools


V. INTRODUCTION:


Electricity is everything in the world of computers. Without a basic knowledge of electronic fundamentals (math), one cannot understand what computers are all about.  At its lowest level, all computers do is add.



VI. Content:


Basic Electronics components, amp flow, electronic terminology, and symbols.

Power Supply voltage measurements

Power Supply pin assignments and voltages

System resources, Bios, Boot process and procedures.



VII. SUMMARY:


By learning basic electronics and the math associated with computers, further understanding of how a computer does what it does will result in easier and more thorough capability to diagnose and troubleshoot problems as they arise.


Students will measure output voltages from the computer power supply and convert the measurements to current and watts. They will determine if the power supply is performing as required.

The students will differentiate between components of the power system to judge the performance of the overall unit.

The ability to component level troubleshoot enables the student, when employed, to assist his boss in maintaining company assets and saving the department and business money.

The ability to accurately measure and test the voltage output from the power supply, and its uses in the computer, are the basis for understanding all future lessons of how a computer operates. It is a fundamental building block for all further lessons.
