An Operating System(OS) is software that manages and handles the hardware and software resources of a computer system. It provides interaction between users of computers and computer hardware. An operating system is responsible for managing and controlling all the activities and sharing of computer resources. An operating system is a low-level Software that includes all the basic functions like processor management, memory management, Error detection, etc.

FAQs on Operating System
Q.1 Why learn Operating Systems?
OS is the most important part of a computer. Through OS users can interact with computer software. It provides an interface between Hardware and CPU. It also provides a platform for the program to run on it and services to users. It performs all the basic tasks required in an application.
Q.2 Write the top 10 Operating System Examples?
Some most popular OS examples are given below:
- Chrome OS
Q.3 What are the Advantages of a multiprocessor system?
A multiprocessor system involves the processing of two or more computer programs simultaneously that share the same memory area. It increases reliability.
Q.4 What is a thread in OS?
