Everything about Central processing unit

Central computer component that executes instructions

A central processing unit (CPU), also known as a central processor, main processor, or simply processor, is the primary processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). Wikipedia →
