FAQs on Operating System: Syllabus Video Lecture - Operating System - Computer Science Engineering (CSE)

1. What is the importance of an operating system in a computer?
Ans. An operating system is crucial for a computer as it acts as an intermediary between the hardware and software components. It manages resources, provides a user interface, facilitates multitasking, and ensures security and stability of the system.
2. How does an operating system manage memory in a computer?
Ans. The operating system allocates and deallocates memory to different processes based on their requirements. It keeps track of available memory, manages virtual memory, and implements memory protection to prevent unauthorized access to memory locations.
3. What are the different types of scheduling algorithms used by operating systems?
Ans. Operating systems employ various scheduling algorithms to manage the execution of processes. Some commonly used scheduling algorithms include First-Come-First-Serve (FCFS), Shortest Job Next (SJN), Round Robin, and Priority Scheduling.
4. What is the role of device drivers in an operating system?
Ans. Device drivers are essential components of an operating system that enable communication between hardware devices and the software. They provide an interface for the operating system to control and access devices such as printers, keyboards, and network adapters.
5. How does an operating system ensure file system integrity?
Ans. An operating system ensures file system integrity by implementing techniques such as journaling, checksums, and redundancy. These mechanisms help detect and recover from file system errors, ensuring that data remains consistent and accessible.
