Correct answer: D. All of these
- A. Data
- B. Instructions
- C. operating system
- D. All of these
Explanation
The correct answer is: (d) All of these.Primary memory, also known as RAM (Random Access Memory), is the computer's main memory. It is volatile memory, meaning that data is lost when the computer is turned off. Primary memory is used to store:Data: Data refers to any information that the computer processes, such as numbers, text, images, and videos.Instructions: Instructions are the set of commands that tell the computer what to do. Programs are stored in primary memory as instructions.Operating system: The operating system is a software program that manages the computer's resources and provides a platform for running other programs. The operating system is also stored in primary memory.While the question stem mentions only these options, it's important to note that technically, primary memory is not used to store programs permanently. Programs are loaded into primary memory from secondary storage (like a hard drive) when they are needed.
