John was teaching his students about the basics of computer hardware and software. By the end of his lecture, he asked his class
to state the basic function that a computer’s control unit performs. Four students answered gave four different answers. George said A) that a control unit performs arithmetical and logical computations. Alex mentioned B)that it stores the data for computations. Helen stated C)that it coordinates the flow of instructions and data within computers. Lastly, Myron suggested D)that it displays results of computations. which one is it?
A CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing basic arithmetic logical, control and input/output operations specified by the instructions. Knowing this, the answer is both C - That it coordinates the flow of instructions and data within computers, And A - That a control unit performs arithmetical and logical computations. If you can only select one answer, I'd personally go with A.
