Andrew S. TanenbaumModern Operating Systems | With New Chapter on Window 11 | Computer security includes digital pests - Virus, Malware etc | Linux and Android Case Study | 5th Edition |

I got original copy of the book authenticated by Pearson thanks to amazon for genuine product deliveryI was expecting some implementation code examples in the book but could not be. It doesn't mean the book is worthless It could be a reference book for learning and developing an operating systemThe book covers all topics related to OS and real-world cases of operating system.

Good
