Control flow (what to do next: a lot can be accomplished with these operations at a very fast pace, each cpu has its own machine language used to give it instructions. Instructions for one cpu typically do not work on another: similar to engine of a car. Some may consider colour, size, and features: characteristics of the cpu, model and make, will determine characteristics of the cpu. Speed: measured in gigahertz (ghz, billions of operations per second. Number of cores: usually has several processors or cores. Power consumption: number of cores affect power consumption. Some processors can slow down or switch to a "low battery mode" Information on secondary memory must be copied onto the primary memory before it can be used.
