A core processor, also known as a central processing unit (CPU), is the primary component of a computer or other electronic device that performs instructions given by software applications. It is often referred to as the “brain” of the computer because it controls all of the processing activities within the device.

A core processor consists of multiple cores, each of which can execute instructions independently. The number of cores in a processor can range from one to many, with more cores typically resulting in better performance and the ability to handle more complex tasks. Modern processors also often include other components such as a memory controller, cache, and graphics processing unit (GPU) to further enhance their capabilities.
