On some architectures, data hazards in CPU pipeline are not resolved automatically. This means that after each instruction which modifies a register there is a slot where the new value of the register is not accessible yet. If the next instruction needs that value, the slot should be occupied by a NOP: imyfone d-back price

"Latency" is the time from the start of the instruction to the point where the result can be used. For example, it takes some time from starting execution of an instruction x = y * z until an instruction a = b + x can start, because the result of the first instruction must first be available.
