Answer:

Does the computer controlling an automobile engine have:

Input devices? Yes—various sensors throughout the car deliver data to the computer.
Output devices? Yes—various actuators have their actions controlled by data.
Main storage? Yes—probably not very much.
Secondary storage? No.

Software

Computer software consists of both programs and data. Programs are lists of instructions for the processor. Data can be any information that a program needs: character data, numerical data, image data, audio data, and countless other types. The distinction between programs and data is not as clear-cut as you might think, however.

Fundamental Idea: Both programs and data are saved in computer memory in the same way. The electronics of computer memory (both main memory and secondary memory) make no distinction between programs and data.

The insight that both programs and data can be saved using the same electronic methods is one of the most important ideas in computer science. Computer systems can use their memory for whatever needs arise.
