Detailed explanation-1: -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-2: -The CPU, often known as the processor, is the computer’s brain. It is in charge of carrying out a program, which is a set of instructions. A program accepts data, processes it, and returns results. By using the stages of the fetch execute cycle, the CPU’s principal responsibility is to execute programs.
Detailed explanation-3: -This is controlled by a clock. With every tick of the clock, the CPU fetches and executes one instruction. The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz.
Detailed explanation-4: -Fetch cycle comprises of several microinstructions . A microinstruction is executed in one clock cycle. So several clock cycles correspond to the Fetch cycle.
