Can anyone tell me what is the difference between Root mean square deviation and standard deviation?

Not much as it turns out, pre-supposing you mean AC RMS. The difference is that standard deviation divides by (N-1) and the RMS calculation divides by N, where N is number of samples. When N is above 100 the difference is going to be unimportant.
