Standard deviation vs volatility

[sfad]

Can standard deviation and volatility be used interchangeably?
E.g. the primary problems with real estate returns are the lack of pricing data, forcing a heavy reliance on appraisal values for investments, and the resulting smoothing of returns and understatement of volatility/standard deviation.
So are they the same here?
