In telecommunication handoff is nothing but,the process of transferring an active call or data session from one cell in a cellular network to another or from one channel in a cell to another.
so there are 4 types of handoff i.e,
Hard handoff
Soft handoff
Softer handoff
Softer handover
Hard handover
thus the soft hand hard handoff have simple difference as follow
Hard handoff: It means that all the old radio links in the MS are removed before the new radio links are established. In GSM, it is general. we can say Break before Make. so in this case higher rates of call drops is found.

Soft Handoff: It means the radio links are added and removed in a way that the MS always keeps at least one radio link to the UTRAN. In CDMA this technique is performed. In simple words we can say Make befor Break. To lower the rates of call drops, this technique is used.
