CPU Time vs Usage (ani.social)

I'm self studying for a server+ cert and ran into this paragraph. Am I right that CPU time is a set of ticks utilized, the CPU Capacity is the total capacity, and the CPU usage is the percentage of ticks:capacity?

I have been making notes from this chapter, and the more I get into it the more I seem to find things like this that seem slightly off.

Does anyone have a physical copy of the 2ed McMillan CompTia Server+ study guide I can compare against? I feel like someone is messing with me.

Sounds about right...

Cpu time is the time your process actually uses the cpu to process things, rather than waiting.

It's often shown as a percentage in top and other performance monitors. So 10% means it's spending 1/10th of the time actually calculating things
