Introduction
This chapter covers the microprocessor areas of the CompTIA A+ Certification—Essentials examination under Objective 1.1. It also covers the cooling systems area of the objective. Computer technicians are often asked to upgrade existing systems with new devices, such as a new microprocessor. Therefore, every technician should be aware of the characteristics of possible CPU upgrades and be able to determine whether a particular upgrade is physically possible and worthwhile.
To be a successful technician, you must be aware of the capabilities of the different microprocessors that are available for use in a system. Technicians must know what impact placing a particular microprocessor in an existing system may have on its operation. They must also be able to identify the type of processor being used and the system settings necessary to maximize its operation.
