Document Summary
Chapter 6: understanding and assessing hardware: evaluating your system. Selecting a computing device: system evaluation: evaluates subsystems to see if system is still good enough or should change computer, huge number of choices: tablets, ultrabooks, netbooks, 2-in-1s, laptops, desktops. Sealed- water cooling solutions also available: hyperthreading: new set of instructions starting before previous set has finished. Measuring cpu performance: cpu benchmarks: measurements used to compare performance between processors. Often published on cpubenchmark. net: cpu usage: percentage of time cpu is working, cpu usage graph: records cpu usage for the past minute, tower design: changing the shape of case holding the computer parts like apple"s marc. Pro 10 inches cylinder built around triangular collection of printed circuit boards allowing constant air flow from bottom to top, cooling all computer components w/ a single fan. In 4gb ram: 1. 1gb used to run hardware systems. 17gb used to hold cache data + files ready for quick access.
