Final answer:
The operating system is stored on the hard disk and in RAM when the computer is running, so option c. Both A or B is the correct answer.
Step-by-step explanation:
The operating system is stored in two places: on the hard disk and in RAM when the computer is running. Initially, the operating system is stored on the hard disk. When you power on your computer, the operating system is loaded from the hard disk into RAM.
This is because RAM allows for faster access to data than a hard disk. Therefore, when your computer is running, the operating system operates from RAM, making the computer more responsive.
To answer the question directly, the operating system is stored both on the hard disk and in RAM when the computer is running. This would make option c. Both A or B the correct choice.
The operating system is stored on the hard disk. When a computer is running, the operating system is loaded from the hard disk into the computer's RAM (Random Access Memory). RAM is a type of computer memory that provides temporary storage for data that is actively being used by the computer. Once the operating system is loaded into RAM, it can perform its functions and manage the computer's resources.
