How This Book Is Organized
This book corresponds closely to the Cisco IT Essentials course and is divided into 12 chapters, one appendix, and a glossary of key terms:
Chapter 1, Introduction to the Personal Computer: Information technology (IT) is the design, development, implementation, support, and management of computer hardware and software applications. A computer is an electronic machine that performs calculations based on a set of instructions. A computer system consists of hardware and software components. This chapter discusses hardware components found in a computer system, selecting replacement computer components, and configurations for specialized computer systems.
Chapter 2, Lab Procedures and Tool Use: This chapter covers basic safety practices for the workplace, hardware and software tools, and the disposal of hazardous materials. Safety guidelines help protect individuals from accidents and injury and protect equipment from damage. Some of these guidelines are designed to protect the environment from contamination by discarded materials. You will also learn how to protect equipment and data and how to properly use hand and software tools.
Chapter 3, Computer Assembly: Assembling computers is a large part of a technician’s job. As a technician, you must work in a logical, methodical manner when working with computer components. At times, you might have to determine whether a component for a customer’s computer needs to be upgraded or replaced. It is important that you develop advanced skills in installation procedures, troubleshooting techniques, and diagnostic methods. This chapter discusses the importance of component compatibility across hardware and software.
