What to learn from the beginning Architecture or OS?

Question

Operating Systems

Hello, I would like to study more deeply what I work on. I study at the university, but there is not much time, so there is doubt about where to start. Will I be able to properly understand the work of operating systems without a deep knowledge of architecture.
There is a book "Modern operating systems" available and I would like to start with it.

Answer 1

Learning architecture at a "deep level" will take a lifetime.
Therefore, learn both the architecture and the OS at the same time, gradually understanding what and how.
There is a book - start. Is it really that long to read a book? Spend less time asking irrelevant questions, more time reading.

Answer 2

Start with the book "CODE. The Secret Language of Computer Science". This is the best introduction to architecture. So interesting that even my wife liked it.
