The CPU performs calculations, makes logical comparisons and moves data up to billions of times per second. It works by executing simple instructions one at a time, triggered by a master timing signal that runs the whole computer.

What is processor how it works?

Processor cores are individual processing units within the computer's central processing unit (CPU). The processor core receives instructions from a single computing task, working with the clock speed to quickly process this information and temporarily store it in the Random Access Memory (RAM).

How does a processor work step by step?

First, an instruction is fetched from memory. Second, the instruction is decoded and the processor figures out what it's being told to do. Third, the instruction is executed and an operation is performed. These three steps repeat in a cycle that begins again with the CPU fetching the next instruction.
