Play a 3D ball bouncing game and save the world from the evil doctor. . What Is Central Processing Unit?. A Central Processing Unit is also called a processor, central processor, or microprocessor. It carries out all the important functions of a computer. It receives instructions from both the hardware and active software and produces output accordingly. It stores all important programs like operating systems and application software. CPU also helps Input and output devices to communicate with each other. Owing to these features of CPU, it is often referred to as the brain of the computer.. A typical computer system irrespective of its size, class or type consists of hardware and software, integrated and harmonized together to perform computational work (scientific or military) or data processing.
