CP102 Lecture Notes - Lecture 6: Overclocking, Hyper-Threading, Control Unit
Document Summary
Things to consider: speed, moore"s law, system components, hard drive storage capacity. Huge number of choices: tablets, ultrabooks, netbooks, tablet pcs, laptops, desktops. Cpu: located on motherboard, processes instrucions, performs calculaions, manages low of informaion, intel i5 and i7 processors. Composed of two units: control unit, arithmeic logic unit (alu) Machine cycle: fetch, decode, execute, store. Cpu"s processing power: clock speed, overclocking, cores, cache memory. Random access memory (ram: short-term memory storage, volaile storage. Read-only memory (rom: start-up instrucions stored here, permanent non-volaile storage. Types: double data rate 3 (ddr3, double data rate 5 (ddr5) Data saved as patern of magneized spots of 1s and 0s. Paterns of spots are translated into data. Short form is ssds: fast access imes, run with no noise, generate litle heat, require litle power. Tiny pits burned into the disc by high-speed lase. Video display depends on two components: video card, monitor. Screen resoluion dialog box: advanced seings.
