CHAPTER SUMMARY


As you have learned in this chapter, the CPU is the core of a computing system. Supporting components and technology that enhance its features surround the CPU. Bus architecture and cache play a major role in the overall performance of a processor. In this chapter, you were guided through a general history of the processor, from the early 8086 to the new Pentium 4 processors. As you have seen, competition has clearly kept the manufacturers continually striving to make a better, faster, more affordable CPU.

As mentioned earlier in this chapter, the new A+ Hardware Service Technician core test is likely to focus on newer processors and bus speeds. You will probably be tested on basic processor troubleshooting and maintenance. Let’s get serious and focus: your future as a skilled technician may depend on it. Imagine that you just paid $150 to take the next practice test. One wrong question, and you lose your money and your shot at getting certified.
