In earlier chapters, we learned that the CPU and motherboard (bus and controllers) are critical components that help determine the overall speed with which a computer can process data. This chapter looks at another important system component and performance factor: memory.
Technicians are often asked to upgrade PCs by adding more memory, and memory conflicts or errors commonly prompt calls for assistance by users. Understanding how memory works, how to choose the right memory for a given system, and how to troubleshoot memory problems is critical to success as a computer technician.
A clear understanding of microprocessors, motherboards, and computer buses, covered in earlier chapters, is required before beginning this chapter.
