When another famous mathematician was in first grade, his teacher asked the class to add up the numbers one through a hundred (1+2+3 etc., all the way up to 100). . Write out the teacher’s request in summation notation, then find the answer (no calculators!) Try to figure out an efficient way!. 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.. Computer. 2. .3 . Central Processing Unit. Central Processing Unit. Central Processing Unit (CPU) consists of the following features −. CPU is considered as the brain of the computer.. CPU performs all types of data processing operations..
