1.
- Answer: A real-time OS processes data instantly for time-critical tasks (e.g., air traffic control), while a multitasking OS runs multiple tasks concurrently without strict timing (e.g., Windows).
- Description: Real-time OS prioritizes speed and reliability for specific applications, unlike multitasking OS, which focuses on general efficiency.
2.
- Answer: The OS uses resource allocation techniques like queuing or prioritization to assign memory, preventing conflicts.
- Description: It ensures fair distribution and avoids crashes by managing access to limited resources like RAM.
3.
- Answer: Benefit: Resource sharing across multiple computers. Concern: Security risks due to network dependency.
- Description: Distributed OS enhances efficiency but requires robust protection against cyber threats.
4.
- Answer: Formatting prepares the drive with a file system (e.g., NTFS), erasing data and making it ready for new storage.
- Description: It’s a critical utility that resets the drive, enabling the OS to read and write data effectively.
5.
- Answer: It made OS more intuitive, reducing the learning curve and broadening accessibility.
- Description: GUIs replaced complex commands with visual elements, benefiting non-technical users significantly.
