Preventive maintenance is the regular and systematic inspection, cleaning, and replacement of worn parts, materials, and systems. Effective preventive maintenance reduces part, material, and system faults, and keeps hardware and software in good working condition.

Troubleshooting is the systematic process used to locate the cause of a fault in a computer system and correct the relevant hardware and software issues.

In this chapter, you will learn general guidelines for creating preventive maintenance programs and troubleshooting procedures. These guidelines are a starting point to help you develop your preventive maintenance and troubleshooting skills.
