Unit V: Instruction Cycle | BCA 3rd Semester Microprocessors Notes Pdf

The basic operation cycle of a computer is the instruction cycle (also known as the fetch-decode-execute cycle). It is the procedure by which a computer gets a program instruction from its memory, identifies the actions required by the instruction, and executes those actions. From the time the computer starts to the time it shuts down, the central processing unit (CPU) repeats this cycle indefinitely.
