CHAPTER 3 SUMMARY 1. How can I determine whether I should upgrade my existing computer or buy a new one? To determine whether you need to upgrade or purchase a new system, you need to define your ideal system and what it can do. Then you need to perform a system evaluation to assess the subsystems in your computer, including the CPU, memory, storage, video, audio, and ports. Last, you need to determine if it’s economically practical to upgrade or whether buying a new computer would be best. 2. What does the CPU do, and how can I evaluate its performance? Your computer’s CPU processes instructions, performs calculations, manages the flow of information through a computer system, and is responsible for processing the data you input into information. It is composed of two units: the arithmetic logic unit and the control unit. CPU speed is measured in megahertz or gigahertz, or millions or billions of machine cycles a second. A machine cycle is the process the CPU goes through to fetch, decode, execute, and store data. You can tell whether your CPU is limiting your system performance by watching how busy it is as you work on your computer. The percentage of time that your CPU is working is referred to as CPU usage, which you can determine by checking the Task Manager. 3.
