Document Summary

Moore"s law: cpu capacity will double every 2 years. Computers usually last 2 years (even up to 4 or 5) Cpu: located on the system motherboard, processes instructions, performs calculations, manages flow of information. Control unit: coordinates the activities of all other components. Alu- arithmetic logic unit: performs all arithmetic calculations and makes logic and comparison decisions. Goes through the same series of steps (machine cycle) Decode: decodes instruction into something the computer understands. Clock speed: dictates how many instructions the cpu can process each second (ghz) Overclocking: running the cpu faster than recommended. Cores contain the parts of the cpu required for processing. Cache memory: form of ram that gets data to the cpu for processing. Level 1: a block of memory on the cpu chip. Level 2: on the cpu chip, slightly farther away. Level 3: larger in size, slower to reach. Cpu benchmarks: measurements used to compare performance between processors.
