Study Notes
Evaluating Computer Components
- Various types of computers to choose from including tablets, ultrabooks, netbooks, tablet PCs, laptops, and desktops
- The CPU is located on the motherboard, processes instructions, performs calculations, and manages flow of information
- The CPU consists of a control unit and an Arithmetic Logic Unit (ALU) and goes through a machine cycle of fetch, decode, execute, and store
- CPU processing power is determined by clock speed, overclocking, number of cores, and cache memory
- RAM is short-term, volatile memory, while ROM stores start-up instructions and is permanent nonvolatile storage
- Types of RAM include DDR3 and DDR5, found in different devices and video graphic cards
- Mechanical hard drives consist of coated platters stacked on a spindle, while solid-state drives have no mechanical parts and are faster and quieter
- Optical drives include Blu-ray, which delivers high definition quality and is used by large displays and monitors
- RAID technology, such as RAID 0 for speed and RAID 1 for security, can be used in hard drives
- Video display quality depends on the video card, monitor, ports, video memory, and GPU
- Audio quality is affected by speakers, sound card, 3-D sound technology, surround sound, and Dolby Digital 7.1
- Proper upkeep and maintenance can improve system reliability and performance, and disposing of old computers should be done responsibly to minimize environmental impact
