Computer Architecture

I have begun reading Bryant, Halloran & Tahiliani’s, Computer Systems, A Programmer’s Perspective.

Notes and thoughts as i follow the book …

Learnt about the origins of the word “context”. The original domain was the os (kernel) context-switching between tasks and saving the context it needed (register state, contents of memory) before it made the actual switch
