Overview:The computer can be called a “universal machine” in that it is capable of doing whatever man is capable of instructing it to do. Dr. C.R. DeCarlo, director of education for IBM, comments on the fact that the computer revolution represents a fundamentally different kind of advance because, unlike the industrial advances, the computer manipulates and processes information at incredible speeds. Of course, the answers and decisions that man gets from a computer depend entirely upon the data and instruction put into the machine.
