What’s the difference between water vapour and steam

Question

What physical differences do water vapour and steam have other than water vapour having a lower temperature? How it is possible for it to exist in the air (I.e. during a hot shower, clouds) whilst being below the boiling point of water? Do the molecules look the same under a microscope?
