The chess.com computer[?]

I am sorry if this topic appeared on these forums thousands of time -i've look on the 2 last page and did not see anything related to it.

So i'm asking

What's the difference between Easy - Normal - Hard computer(On chess.com) ?
Will the easy blunder if it judges it has advantage on you ?

I'm really curious about it .

Easy = approximately 1200 rating

Medium = approximately 1500 rating

Hard = approximately 2000 rating

Or so I believe I read on the site somewhere.

The Hard one is weaker than 2000, IMO. It falls to well coordinated kingside attacks, and it doesn't percieve opening of columns as losing moves in certain situations. These are things a 2000 rated player would be well aware of.
