INTRODUCTION:

The fundamental element of a computer that handles the majority of data processing activities is a processor, commonly referred to as a central processing unit (CPU). It is responsible for executing instructions and doing calculations that are necessary for a computer to function properly.

Working of processor:

The control unit and the arithmetic logic unit are the two primary parts of the processor (ALU). The control unit is responsible for fetching instructions from memory, decoding them, and then executing them in the right sequence. Arithmetic and logical operations including addition, subtraction, multiplication, and division are carried out by the ALU.

The fetch-decode-execute cycle serves as the foundation for the processor’s operation. In this cycle, the processor gets an instruction from memory, decodes it, and then executes it. Up until the program’s conclusion, this process is continuously repeated.

The fetch step is the first one in the fetch-decode-execute cycle. This phase involves the CPU retrieving the subsequent instruction from memory using a register called the programme counter.

CONCLUSION:

In conclusion, the processor is the brain of a computer, responsible for doing the fundamental computations and executing instructions required for a computer to work. The fundamental operation of a processor is the fetch-decode-execute cycle, and there are various types of processors based on their architecture, clock speed, and number of cores.
