I am preparing this handbook as part of [\"The Bit Series\"](http://elvissaravia.com/books/). Read more about our manifesto [here](http://elvissaravia.com/books/). Also, feel free to submit pull requests as there might be plenty of grammatical errors, spelling errors, and even inconsistencies in the content. I will try to update the book as frequently as possible. I am also keeping a log of my continuous updates [here](https://github.com/omarsar/os/blob/master/log.md). It is tough doing this alone, so I am definitely crediting anyone for their contributions. \n\n### :point_right: Table of Content\n\n- Chapter 1 - [Introduction to Operating Systems](https://github.com/omarsar/os/blob/master/1.%20Introduction%20to%20Operating%20Systems.md)\n- Chapter 2 - [Process Management](https://github.com/omarsar/os/blob/master/2.%20Process%20Management.md)\n- Chapter 3 - [Process Management (Distributed Environment)](https://github.com/omarsar/os/blob/master/3.%20Process%20Managment%20(Disitributed%20Environment).md)\n- Chapter 4 - [Concurrent Processing](https://github.com/omarsar/os/blob/master/4.%20Concurrent%20Processing.md)\n- Chapter 5 - [Critical Section Problem](https://github.com/omarsar/os/blob/master/5.%20Critical%20Section%20Problem.md)\n- Chapter 6 - [Deadlock - Part 1 (Theory)](https://github.com/omarsar/os/blob/master/6.%20Deadlock%20-%20Part%201%20(Theory).md)\n- Chapter 6 - [Deadlock - Part 2 (Algorithms)](https://github.com/omarsar/os/blob/master/6.%20Deadlock%20-%20Part%202%20(Algorithms).md)\n- Chapter 6 - [Deadlock - Part 3 (Distributed Environment)](https://github.com/omarsar/os/blob/master/6.%20Deadlock%20-%20Part%203%20(Distributed%20Environment).md)\n- Chapter 7 - [Memory Management](https://github.com/omarsar/os/blob/master/7.%20Memory%20Management.md)\n- Chapter 8 - [Cache Memory](https://github.com/omarsar/os/blob/master/8.%20Cache%20Memory.md)\n- Chapter 9 - [Secondary Storage](https://github.com/omarsar/os/blob/master/9.%20Secondary%20Storage.md)\n- Chapter 10 - [Buffer Cache](https://github.com/omarsar/os/blob/master/10.%20Buffer%20Cache.md)\n- Chapter 11 - [File Representation](https://github.com/omarsar/os/blob/master/11.%20File%20Representation.md)\n\n### :point_right: Status\n- Draft stage\n\n### :point_right: TODO List\n- Add examples through images. \n- Add proper tables and fix code segments\n\n### :point_right: Contributor\n- [Elvis Saravia](http://elvissaravia.com)\n- Email: ellfae@gmail.com\n\n### :point_right: Potential book cover\n![alt-text-1](https://github.com/omarsar/omarsar.github.io/blob/master/images/os.png?raw=true)\n\n### :point_right: More from \"The Bit Series\"\n![alt-text-2](https://github.com/omarsar/omarsar.github.io/blob/master/images/machine-learning.png?raw=true)\n\n- [Machine Learning: A Friendly Handbook](https://github.com/omarsar/machine_learning_fundamentals)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fomarsar%2Fos","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fomarsar%2Fos","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fomarsar%2Fos/lists"}
