In the first half of this year, I devoted myself to writing about the operating system. Some of you knew that I had been writing about the operating system, and some of you didn’t. Whether you knew it or not, you should know by now.

Since February, I’ve posted more than a dozen hardcore articles on operating systems, and now I’ve compiled them all into a PDF, which you can check out in the table of contents

Contents:

  • Understanding the operating system
  • Processes and threads
  • Memory management
  • File management
  • I/O
  • A deadlock
  • Operating system interview questions
  • Core concepts of the operating system

Each chapter has a mind map

And errors in the book that I flagged

I did 99% of the drawings with my hands. Many friends asked me what I used to make the picture. This is the use of the Mac keynote drawing.

This PDF is a total of **306** pages, 17W words, I think this should be the first operating system PDF in the whole network, I hope you can treasure it.

It is simply used up my experience of half a year, painstaking work, now free to share with you.

Pay attention to the public number “code farmers turn over record”, reply 888, free download. After paying attention, you will receive high quality technology and job sharing from time to time, I hope to accompany you to move forward with your dream.
