CPU |
-central processing unit (silicon chip) -located on the motherboard -interprets and executes instructions -performs arithmetic and logical data manipulations -communicates with the other parts of the computer system -fetch, decode, execute |
|
|
Compatibility |
-software is written specifically for certain processors -Built in instruction set or vocabulary of instructions that only the processor can execute -CPU's are designed to be backward compatible |
|
|
Speed |
