Unit 6 understanding and assessing hardware: evaluating your. Moore"s law: pace at which cpus improve. Manages flow of information through the computer system. Responsible for processing data you input into info. Composed of 2 units: control unit. Coordinates activities of all the other computer components: arithmetic logic unit (alu) Makes logic and comparison decisions (i. e. comparing items to determine if one is greater than, less than, equal to, or not equal to another) Core: complete processing section from a cpu embedded into the same physical chip. Clock speed: how quickly the processor works. Cache: amount of immediate access memory the cpu has. Physical memory: amount of ram actually sitting on memory modules in the computer. Kernel memory: memory that the operating system uses. Determining how much ram your computer needs: look at the memory requirements for each program and add them up. Adding ram can have a big positive effect on system performance.
