By the functions of a computer, I think you mean the tasks a computer can do. So here they are, 1) Diligence - A computer is highly diligent, meaning it can perform the same task multiple times. 2) Accuracy and Speed - A computer can solve arithmetic operations much faster and correct then an average human brain. 3) Memory - A computer can store a lot of data and information in its memory. Hope I helped:))
