Document Summary
Chapter 6: understanding and assessing your hardware: evaluating your system: moore"s law dictates that cpu speed will double every 18 months, external hard drives can drastically increase the memory of a notebook. The cpu is located on the motherboard (motherboard: primary circuit board of a computer) Cpu is comprised of two units: the control unit that coordinates all other parts of the computer, the arithmetic logic unit preforms all math calculations and makes logical decisions (this larger than, less than, equal to that, etc) A machine cycle in a computer proceeds as: cpu retrieves instruction from the ram, decodes instruction into computer language, executes the instruction, stores result in ram. Netbook cpus are different than desktop cpus because they must use low power to increase battery life and have increased flexibility in connectivity options. Cpu usage is referred to as the percentage of time that your cpu is working, to view information on this usage, open the task manager.
