Even though we make use of merge and concat operators for same purpose that is combining the values of different observable sources, both has significant difference.

If you have two observables emitting values and you want to merge values of two observables as soon as they emit the values use a merge operator.

If you have two observables emitting values and you want to combine values of two as soon as previous completes emitting the values, use a concat operator. You can think of concat like a line at a ATM, the next transaction (subscription) cannot start until the previous completes.
