CP102 Chapter Notes -Dynamic Random-Access Memory, Static Random-Access Memory, Expresscard
Document Summary
Ch6 understanding and assessing hardware: evaluating your system. Moore"s law: describes the pace at which cpus improve (cpu: central processing unit, brains of computer) Dynamic random access memory (dram): most common form of memory found in computers, increases about 60% each year and hard drives grow in storage capacity by 50% each year. Portability is the main distinction between desktops and notebooks: desktops have more processing power, memory, storage capacity for lower price. Expresscard: can add a solid-state drive (ssd), esata and firewire ports and other capabilities to your system. System evaluation: determines whether your computer system has the right hardware components to do what you want it to do. Cpu: processes instructions, performs, calculations, and manages the flow of information through a computer system: responsible for turning raw data into valuable information through processing operations, 2 units: control and arithmetic logic unit (alu) Located on the motherboard control: coordinates the activities of all the other computer components.
