Taken from the CompTIA IT Fundamentals Exam Guide book (2nd edition, published 2021). I'm not sure if they fixed this in newer versions, if at all.
Just calling it ISO isn’t a good idea for an intro class like that because it is a set of MANY standards. They should have put a little side blurb and called it ISO 9660 in the table.
This is the only thing here I disagree with. The table is quite clearly putting extensions on the left and intro classes do not need to know about the International Organization for Standardization.
