What is CPU?

CPU stands for Central Processing Unit. It is often referred to as the “brain” of a computer or a computing device.The CPU fetches instructions from memory, decodes them to understand what operation needs to be performed, and then executes those operations using its internal circuitry. This process occurs in a cycle known as the “fetch-decode-execute” cycle, where the CPU retrieves instructions, interprets them, and carries out the necessary actions.

Modern CPUs are designed to handle a wide range of instructions efficiently, making them the core component that drives the functionality and performance of a computer system. It interprets and carries out instructions from the computer’s memory, performing tasks such as calculations, data processing, and managing the overall operation of the computer system.

Modern CPUs are highly complex and can handle a wide range of tasks, from simple calculations to complex simulations and multitasking. They consist of multiple cores, each capable of executing instructions independently, which allows for better performance in handling multiple tasks simultaneously.

CPUs come in various architectures and are a crucial component in determining the overall speed and performance of a computer. As technology has advanced, CPUs have become faster, more efficient, and capable of handling increasingly complex operations.
