    In computing, the two-phase cycle used by the computer's central processing unit to process the instructions in a program. During the fetch phase, the next program instruction is transferred from the computer's immediate-access memory to the instruction register (memory location used to hold the instruction while it is being executed). During the execute phase, the instruction is decoded and obeyed. The process is repeated in a continuous loop.
