Operating system

The operating system (OS) is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs and applications. As operating system is heart for computer similarly operating system is also key subject for computer science students.

  • Operating systems provide the crucial interface between a computer’s hardware and the applications that run on it.
  • It allows us to write programs without bothering much about the hardware.
  • It also ensures that the computer’s resources such as its CPU, hard disk, and memory, are appropriately utilized.

The theoretical and practical knowledge of operating system essential to understands the working of computer system.

Theoretical knowledge of Operating System

There are many resources which are free and easily accessible to learn operating system as subject. Here I am suggesting 2 books which I personally feel helpful to learn Operating system.

  1. Operating System Concepts: Abraham Silberschatz, Greg Gagne, Peter B. Galvin
    In this book author has explained operating system in gravity. The text includes content to bridge the gap between concepts and actual implementations. End-of-chapter problems, exercises, review questions, and programming exercises help to further reinforce important concepts.
  2. Operating Systems – William Stallings
    This book covers fundamental technology as well as contemporary design issues, such as threads, microkernels, SMPs, real-time systems, multiprocessor scheduling, embedded OSs, distributed systems, clusters, security, and object-oriented design.

Here you may find various practical approach to understand operating system.

Practical knowledge of Operating System

One can have practical knowledge of operating system when someone do the practical with operating system. So whenever you work with your computer go to task manager and try to explore it.

Anyone who is acutely interested in learning operating system practically may go to learn basics of UNIX/Linux operating system, where he can learn commands to handle processes, files and different resource management.

If some wants to explore algorithmic part of operating system’s management task, should learn design of operating system, try to code these algorithm in any programming language.

Here is the link where you can learn UNIX/Linux Basics

Last but not the least suggestion is always relate subject with real world, you will never find it difficult.

I am Rashmi Vishwakarma, working at careerhunt , Before this I worked as an Assistant professor and Academic project guide at Gyan Ganga Institute of Technology and Sciences ,Jabalpur for 5 years. I also strive to provide individual attention to each student, get to know them well, as I feel the learners should be more comfortable and confident about their teacher first. Looking at, my academic profile I have completed my MCA in 2008 with Hon’s degree and also held bachelor degree in Computer Science from Rani Durgawati University, Jabalpur.
