Ans: The pipeline can be stalled due to delay in the availability of an instruction. For instance, this may be a result of a miss in the cache, needing the instruction to be fetched from the primary memory. Such hazards are frequently called control hazards or instruction hazard.
Explained delayed branching?
Ans: Delayed branching which is used to minimize the penalty incurred as a result of conditional branch instruction. The following location of the branch instruction is known as delay slot.
