I practiced a similar question, and I think both 'us' and 'sy' are the ones we need for user and system time.

I feel like 'id' is definitely related to idle time, but I'm confused about what that means for kernel versus non-kernel.

I'm not entirely sure, but I remember 'sy' is for system processes, so that must be kernel code.

I think the 'us' column shows the percent of time spent on user processes, which is non-kernel code, right?
