What is the source of Computer data?

Computer data can originate from both primary and secondary sources.

• Primary sources refer to data entered directly into the computer in real-time, such as user input via a keyboard or mouse, or data from sensors.
• Secondary sources involve data retrieved from storage devices like hard drives, SSDs, USB drives, or network servers, where it was previously saved.

Therefore, a computer system is designed to process information from both immediate input and stored records. Options A and B are incomplete as they only cover one type of source, and option D is incorrect.
