Question

Which of the following is the correct order of the four major functions of a computer?

• A. Process $\stackrel{\sim }{A}$ Output $\stackrel{\sim }{A}$ Input $\stackrel{\sim }{A}$ Storage
• B. Input $\stackrel{\sim }{A}$ Output $\stackrel{\sim }{A}$ Process $\stackrel{\sim }{A}$ Storage
• C. Process $\stackrel{\sim }{A}$ Storage $\stackrel{\sim }{A}$ Input $\stackrel{\sim }{A}$ Output
• D. Input $\stackrel{\sim }{A}$ Process $\stackrel{\sim }{A}$ Output $\stackrel{\sim }{A}$ Storage

Answer 1

The correct option is D Input $\stackrel{\sim }{A}$ Process $\stackrel{\sim }{A}$ Output $\stackrel{\sim }{A}$ Storage

Input A∼ Process A∼ Output A∼ Storage is the correct order of the four major functions of a computer.

A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. The processing of input to output is directed by the software but performed by the hardware.

The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process.
