The principles, techniques and skills taught in the modules,.basedon tasks that energy technicians perform, were obtained from a nationwide advisory committee ofemployers of energy technicians. Each module written by a technical expert and apprOved byrepresentatives from industry. A A module contains the following-elements: Introduction, which identifies the topic and often includesa rationale for studOPN,the material._ Rrerequisites, which identify the material a stUdent.should befamiliar with before studying the module. 'Objectives, which clearly identify hat the studentis expected to know for sat- isfactory module completion. The objectives, stated in terms of action-oriented behaviors, include such action wordsas operate. measure, calculate, identify and dcilne,:rather than words withmany interpret,atienst such as know, under- stand, learn and appreciate. Subject Matter, which presents the background,theoryand techniques supportive k to the objectives of the module. Subject matter is written with the technical student in mind. , Exercises; which provide practical problems to 'which thestudent Gran apply ,his new knowledge.

IP> INTRODUCTION Computers are logic devicescomposed of a vast array'of elementary logic gates. These gates oftenare used singly or in simple combinations incomputer support circuits such . as memory, input/output and clocks. This module investgaves the logical properties ofthese gates andsome of the basic digital circuits thatcan be made from them. PREREQUISITES The Student should havecompleted the course in Micro- computer Operations and have theability to us d.c. instru- ments and to breadboard integratedcircuits (IC). OBJECTIVES Upon completion of thismodule, the student shouldbe able to: 1. Predict'output from multiplegate circuit schematics by using truth table's and standardlogic symbols. 2.

CHANtES.AD THECOMPUTER'S COMPONENTS Since the first generation'ofdigital tomputer hardwiare appeared in,the 1940's, themomentum of changing corriputr technology 'has grown aten 'ever - increasingpace,. The challenge fortechniciansinvolved withcomputcr __Hardware, includingtechnicians ip energy conservation and 1 V a use, is to keep abreast_of-these rapidly-changing 4'pvelop- ments. ?his introductory course in computer hardwaresummarizes- the basic logic components found in all digitalcomputers, as well as basic digital electronics and simpletroubleshooting technique. Students should realize,however, that in this environment of technologicalchange, the hardware, encountered in the field will bewide-ranging inappearance and function. The term. "microcomputer"refers to a digital computing device that utilizesan advanced solid-state micropcessor. Microprocessiirs 'Werefirst'introduced in 1971as a result of Large Scale Intevatiow (LSI) technology, which enabledthe -construction of a 'single silicon- Integrat.ed Circuit (IC)con- taining the miniaturized logic devices required bycomputers, which will be detailedin this course. Hardware refers tothe physicalcomponents and circuitry that make-up a digital computer. Software refers to'programs,
