Detailed explanation-1: -The fetch-execute cycle (also known as fetch-decode-execute cycle) is followed by a processor to process an instruction . The cycle consists of several stages. The memory address held in the program counter is copied into the MAR . The address in the program counter is then incremented-increased-by one.
Detailed explanation-2: -Explanation: The fetch execution cycle refers to the execution of instructions by the CPU. This is a multi-step process in which instructions are fetched, decoded, executed, and then stored. The result of this cycle allows an instruction to be executed by the CPU allowing the process cycle to continue.
Detailed explanation-3: -The basic operation of a computer is called the ‘fetch-execute’ cycle. The CPU is designed to understand a set of instructions-the instruction set. It fetches the instructions from the main memory and executes them. This is done repeatedly from when the computer is booted up to when it is shut down.
