"His way of explaining complex concept is Great. I started to understand little bit that this is base for all programming language. I have around 12 years of IT experience. Hope OS learning should be mandatory to all before starting their career in IT" by Happy.

"Very good explanation of all the learning materials. He is unlike many other instructors who just throws things out to you expecting you to absorb the things that are being thrown at you. He is someone who explains things in a manner that is understandable and absorbable even to O/S beginners with only limited knowledge or background in O/S. Two thumbs up from me. Thank you so much. " by Mike

"I really enjoyed this course. Instructor made it seems like he is standing there and wouldn't leave the screen until the concepts gets into your head. So much engaging and wherever he says, we will see this later. He make sure you will. I totally recommend" by Surbhi Vasudeva

"excellent course i had started with 0 knowledge now i had learned so much best lecturer super planning of schedule" by Harshavardhan Gupta

"I really enjoyed the course and the instructor provided a great overview of the fundamentals of the theory behind operating systems. In case you are confused, the course is theoretical as opposed to a walk through of how to use Windows, Mac, etc. Instead, he provides an overview of the algorithms used to move processes from RAM to the CPU. I look forward to Part 2" by John Simons

"Great, very detailed course. Ideal for non IT-educated students like me" by Michal Burdzy

"Great Teacher. Takes concepts slow and repeats definitions and meanings multiple times so there is no need to pause the video or rewind it to hear a definition. Uses this practice to reinforce the material in your mind and ensure you actually learn it rather than hear it" by Sam Debois

The course series (part 1 to 4) on operating systems is a whopping 46 hours long. Because the course is designed as a one stop shop for Operating System Concepts. And this 46 hours dedication will change your way of thinking towards computer science.

Why would you choose to learn Operating Systems ?

The reality is that there are a lot of computer science subjects out there. It's in the hundreds. Why would you choose the operating systems subject?

The reason is starting most of the subjects of computer science will become far more easier if you have a good understanding of operating systems. By learning this subject you are not only getting started with operating system but also getting started with computer science.

What textbook should I follow ?

I have used operating system concepts by Galvin. Its a great textbook. You can follow it. But I have referred lot of other textbooks like Tanenbaum, William Stallings, etc. So its upto you on which textbook you are comfortable with but follow a standard author book. If you complete this course, you will find it much easier to understand these textbooks. But anyway if you complete this course with good detailed notes, you don't need to read any textbook as I am reading them for you and giving the contents in an easy to understand manner.Why should you take this course?It's been a best seller since it's release on Udemy, you would be joining over 2700 students who are already enrolled in the course.

There are close to 500 reviews left by students. It's rated as the best course to learn operating system for beginners.What makes this course a bestseller?

Like you, thousands of others were frustrated and fed up with incomplete Youtube tutorials which assume you already know a bunch of stuff and also bulk textbooks able to send even the most intuitive person to sleep.

Like you, they were tired of low-quality lessons, poorly explained topics and all-round confusing info presented in the wrong way. That’s why so many find success in this complete Operating System course. It’s designed in a simple manner so that anybody with no prior knowledge of operating system/computer science will be able to understand.

What if I have questions?

You can ask questions anytime using the Q/A section or through personal messages. I take it very seriously and answer these questions in a detailed manner with simple english words so that anybody can understand it.

Student Quote: “Everything you always wanted to know about OS but were afraid to ask"...And Vignesh Sekar gives the right answers” by Claus Kaliba.

There’s no risk either.

This course comes with a full 30 day money-back guarantee. Meaning if you are not completely satisfied with the course or your progress, simply let me know and I’ll refund you 100%, every last penny no questions asked.

You either end up with Operating System skills, learn other core computer subjects, get placed in top notch companies or research areas or you try the course and simply get all your money back if you don’t like it…

You literally can’t lose.
