Adding new section about operation systems.

[deyan-georgiev]

I've noticed that there aren't any chapters about operation systems in general. I suggest the following content to be added:

OS 101

1. What is OS, Why do we need OS
2. What is kernel
   A short description of what is a kernel
3. User land vs kernel land
   Differences and how they communicate
4. User interfaces
   Different ways to interact with the machine. CLI and GUI
5. File systems
   Short introduction about file systems without going in depth
6. Application software
   Description of some common application software which often ships with the OS - File browser, web browser, text editors

OS 102

1. Architectures
2. File systems in depth
   More information about file systems like partitioning, block sizes etc..
3. Kernel in depth
   A few things about processes, scheduling, networks(maybe), how multi-user OS works. Maybe a few more things about kernels
4. Boot process
   Short description of generic boot process. Detailed description must be added in the sections for Unix and Windows

If the community agrees with my proposal, I'm ready to start writing.

@deyan-georgiev Thanks for asking!

Have you read through http://www.opsschool.org/en/latest/boot_process_101.html ? There's some of the topics covered briefly - it might make sense to determine a better structure for this information with the additions you're proposing.
