We say that a distribution is symmetric, if it is equally balanced on both sides of the mean. This means that the frequency of observations on both sides is equal.
However, if the frequency of occurrence of observations is more in a particular direction then the distribution is asymmetric. This asymmetry of the distribution on either side of the mean is called skewness.
