The central processing unit (CPU), also known as the main processor, is the brain of the computer responsible for executing instructions through its two primary components: the control unit (CU) and the arithmetic logic unit (ALU). The CPU processes basic arithmetic and logical operations while reliant on memory types, such as volatile (RAM) and non-volatile (ROM), for temporary and permanent data storage. The CPU cannot store entire programs but needs sufficient memory space for operations during usage.
