Resource summary
Fetch-decode-excecute
The data AND the instructions are stored in the RAM
The CPU sends a signal along the address bus requesting the next instruction
The data inside the requested address is then sent to the CPU to be processed
This data is then either executed by the CPU if its an instruction or processed if its data
The control unit decodes the data
If needed the ALU acts upon the information
Finally this is sent to an output device or secondary storage.
