Answer:
In general, a vapour refers to the gas phase of a substance below critical temperature. This means that if pressure changes, the gas can become a liquid without a required temperature change. This can apply to any substance.
Steam in general refers to the gas phase of water. Steam can be the same as water vapour in some contexts. In more casual usage, steam can refer to the mixture of vapour and aerosol liquid water droplets suspended in the vapour. The "steam" you see rising off boiling water for example, is the second type. What you see is actually condensed liquid water; as water vapour itself is not visible to the naked eye.
