Computer stores
- A.
Data only
- B.
Instructions only
- C.
Both data and instruction
- D.
Randomly only
Correct Answer
C. Both data and instructionExplanation
A computer stores both data and instructions because it needs both to perform tasks. Data refers to the information that the computer processes, such as numbers, text, or images. Instructions, on the other hand, are the commands that tell the computer what operations to perform on the data. Without instructions, the computer would not know what to do with the data it receives. Similarly, without data, the computer would have nothing to work on. Therefore, a computer needs to store both data and instructions in order to function properly.Rate this question:
