Why pay despite this ✅

Many students tend to be lax about free classes. It's like a neighborhood gym that's always there. In fact, there are many ways to exercise without spending money. Nevertheless, many people still pay money to go to the gym. That's why I made the classes paid.

  • I sincerely hope that those who purchase this course will complete it to the end, even if it means wasting their money!
  • You can study more comfortably without ads through the Inflearn environment .
  • In the future, we will be adding several classes that are not on YouTube.

Operating systems you must know ,
As easy and light as possible! 💪

This lecture is prepared for those who have completed the lecture ' Memorize broadly and shallowly to become a computer science major '. The theory of operating systems is a required subject for computer science majors, so it is a core basic theory that will serve as a foundation for understanding IT technology in general. Therefore, those who wish to become engineers and developers in the IT technology field must know it.

Operating system , complicated and unfamiliar?
Anyone can learn like a CS major.
 

Operating system theory learned by computer engineering majors
We will inform you as easily, quickly, and lightly as possible.

The core of the OS that needs no further explanation! 👨‍🎓

Do you want to build a deeper foundation of theory after studying the previous lecture, 'Memorize broadly and shallowly to become a computer science major'? We will cover the core operating system theories that everyone who wants to go beyond the basic level and fully enter the IT world must know.

Regardless of major, I hope that all developers in our country can gain basic knowledge equivalent to that of computer engineering majors, so I will teach you as easily and lightly as possible. Let's take on the challenge together!

A full set of CS that a laid-back developer can 'memorize and finish' 📚

    (25/07/19/토 10:25) OS에 대해 많이 이해 했습니다. 이 강의를 들으니, 널널님의 강의를 모두 들어야 겠다는 생각이 드네요. 좋은 강의 만들어 주셔서 감사합니다.
