The Fetch-Execute Cycle, also known as the instruction cycle, is the basic operational process of a computer's central processing unit (CPU) where it retrieves an instruction from memory, decodes it, executes it, and then moves to the next instruction. This cycle is fundamental to the operation of a computer, as it allows the CPU to systematically process instructions and perform tasks efficiently.

Fetch-Execute Cycle

The instruction cycle is the fundamental process through which a computer retrieves, decodes, and executes instructions from memory, forming the backbone of CPU operations. It ensures that each instruction is processed in a systematic manner, optimizing the performance and efficiency of computing tasks.

operational process

The central processing unit (CPU) is the primary component of a computer that performs most of the processing inside a computer. It executes instructions from programs by performing basic arithmetic, logical, control, and input/output operations specified by the instructions.

central processing unit

The CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing inside a computer, executing instructions from programs through basic arithmetic, logical, control, and input/output operations. It is often referred to as the 'brain' of the computer, significantly influencing the overall speed and performance of the system.
