Questions about example sentences with, and the definition and usage of "Tier"

A: Here, the word is being used to mean 'component' or 'part' of a system that is at a different 'level' . This diagram is not a typical everyday use of the word. The word 'tier' makes it sound as if 'app' is at a higher level than 'web' in quality. Really, 'app' is just farther down the output of the system.

A: In this context "tier" and "level" are fairly synonymous.

"Tier" is a measure purely of comparison - for example a "top tier" item is better than all of the items in the tiers lower than it. "Bottom tier" is worse than all of the items above it. Tiers are generally considered "higher" or "lower" than each other.
"Tier" is a more subjective measurement, and only a limited number of things can be in the higher tiers. If everybody's the best, nobody's the best!

"Level" is a more objective measurement - for example "Level 50 item". There is a concrete statistic related to the statement. Even if you said something like "high level item" instead of the specific number, you're describing the objective statistic (level 50) in a subjective way (if level 50 is the highest an item can go, then a level 50 item could be considered high level). "Level" generally does not have a limit on how many things can be considered of that level. Similar to tiers, they are also generally considered "higher" or "lower" than the others.

"God tier" would be the native way of phrasing it. It's generally analogous to "top tier", or "one of the best". It's often used in a slightly humorous/exaggerated manner.
For example, if I said "My friend is a god tier gamer," that would mean that I think that my friend is one of the best gamers out there.

This distinction is important because something can be "high level" but "low tier", or vice versa. Just because the item is level 50 doesn't mean that it's a good item, and just because the item is level 1 doesn't mean that it's a bad item.

A: Tier is mostly used for ranks lets say, while class on the other hand has some meanings like your School room: "I am going to my class"
Level is not really used to express it though, level can be used for pretty much everything
"Level of security is high"
But you cant say "Your level is general, right?"

So to sum up Tier is high meaning word which is used to say class/level.
It can't mean much so Tier should be used at some situations while class/level have other meanings that can cover up what you wanted to say.
