and has its own address. The processor takes this address number
from the program counter, which is responsible for tracking which
instructions the CPU should execute next.
Decode Correct Answer - Decode: All programs to be executed

decoded into binary instructions, which are understandable to your
CPU. This step is called decodin
Execute Correct Answer - While executing instructions the
CPU can do one of three things: Do calculations with its ALU, move
data from one memory location to another, or jump to a different
address.
Store Correct Answer - The CPU must give feedback after
executing an instruction, and the output data is written to the
memory.
