In a multitasking operating system, what role does RAM primarily play when multiple applications are open simultaneously?​

Correct option is B

The correct answer is:(b) It temporarily holds active program data and instructions to enable fast switching between tasks.

Explanation:
In a multitasking operating system, RAM (Random Access Memory) acts as the temporary storage for data and instructions that are currently being used or processed by the CPU. When multiple applications are open, RAM holds their active data and program instructions, allowing for fast access and quick switching between tasks. This is crucial for efficient multitasking, as it enables the operating system to switch between active applications without needing to reload their data from slower storage devices like hard drives.

Information Booster:

• RAM is volatile memory, meaning it only retains data while the computer is powered on.
• The operating system allocates portions of RAM to different applications and processes, ensuring that they have enough memory to operate smoothly.
• The system uses virtual memory (often utilizing a swap file) when the available physical RAM is insufficient.
• Multitasking allows users to run multiple applications at the same time, and RAM plays a key role in storing and managing the necessary data for these tasks.

Additional Information:

• (a) It acts as permanent storage for installed software: Incorrect, as permanent storage is handled by hard drives or SSDs, not RAM.
• (c) It queues printing tasks before they reach the printer: This is typically managed by the print spooler, not directly by RAM.
• (d) It processes user input commands from external devices like keyboard or mouse: User input is processed by the operating system and the CPU, with RAM used for temporary data storage, not directly for processing input.
