Detailed explanation-1: -The Central Processing Unit (CPU) is the brain of the computer because it is what makes all the decisions and it is where all programs are executed. The purpose of the CPU is to process data. The CPU works by following a process known as ‘fetch, decode and execute’.
Detailed explanation-2: -Fetch, decode and execute cycle are the three steps that the CPU repetitively performs to complete one program instruction. The control unit decodes the machine instructions following the instruction format.
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.
