A dependency does not always cause a hazard. While a hazard arises when there is a dependency between instructions and their execution overlaps in a way that could change the order of accessing operands, not all dependencies result in hazards. This is because dependencies only lead to hazards when they affect the correct flow of data or control in a program. For instance, in pipelines, dependent instructions may not overlap closely enough to cause a conflict, meaning that the processor can execute them without stalling. Furthermore, modern compilers and processors often use techniques like instruction reordering, register renaming, and speculation to avoid hazards while respecting the dependencies. Additionally, some types of dependencies, such as RAR $($Read After Read$),$ do not cause hazards since both instructions are merely reading values without the risk of altering them. Therefore, while dependencies can create hazards, they do not always lead to them if proper management techniques are in place.$\backslash$
