Hello, I would like to acquire knowledge on the topic in object, in particular:

Process Execution and/or Threads
· Memory Usage
· RAID Levels
· The kernel and how it interacts with other system components
· System Calls
· Signals and Signal Handlers

To be able to respond to questions like:
Do you have an understanding of the relationship between the kernel and the user applications?
Do you understand on which resource something will get bottlenecked and how to determine that?
Do you understand some of the common tools on a typical Linux system?
Do you understand some common patterns to solve systems problems?

Do you know where to start and resources I could look into?

Thanks in advance for any suggestion!

Happy leetcoding
