This algorithm outlines the basic steps that a CPU performs from initial boot-up until the computer is shut down. It repeats continually to process every instruction in a program. The steps involve fetching the instruction from memory, decoding the instruction, executing the instruction, and then updating the program counter to point to the next instruction.
