FAQs on Operating Systems: Crash Course Computer Science #18 Video Lecture - Understanding the Basics of Computer Science and Technology - Basic Technology

1. What is an operating system?
Ans. An operating system is a software that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between the user and the computer hardware, allowing users to interact with the system and run applications.
2. What are the functions of an operating system?
Ans. The functions of an operating system include managing memory, managing processes and scheduling, providing file system and disk management, handling input and output devices, managing security and user access, and providing a user interface for interaction with the system.
3. What is the difference between a kernel and an operating system?
Ans. The kernel is the core component of an operating system, responsible for managing the system's resources and providing essential services. It is part of the operating system but not the entire operating system. The operating system includes the kernel along with additional software and utilities that enhance its functionality.
4. What are the different types of operating systems?
Ans. There are several types of operating systems, including: - Windows: Developed by Microsoft, it is a popular operating system for personal computers. - macOS: Developed by Apple, it is the operating system used on Mac computers. - Linux: A free and open-source operating system used on a wide range of devices, including servers, smartphones, and embedded systems. - Android: A mobile operating system based on the Linux kernel, primarily used on smartphones and tablets. - iOS: The operating system used on Apple's mobile devices, such as iPhones and iPads.
5. How does an operating system handle multitasking?
Ans. An operating system handles multitasking by allocating CPU time to different processes or tasks. It uses scheduling algorithms to determine the order in which processes are executed and switches between them rapidly, giving the illusion of simultaneous execution. The operating system also manages memory to allow multiple processes to run concurrently and provides mechanisms for inter-process communication.
