Q:

What are the different hazards? How do you avoid them?

Answer

There are situations, called hazards, that prevent the next insturction in the instruction stream from executing during its designated clock cycle. hazards reduce the performance from the ideal speedup gained by pipelining.

There are three classes of Hazards:

1. Structural hazards: It arise from resource conficts when the hardware cannot support all possible combinations of instructions simultaniously in overlapped execution.

2. Data Hazards: It arise when an instruction depends on the results of previous instruction in a way that is exposed by the overlapping of instructions in the pipeline.

3.control hazards. it arise from the pipelining of branches and other instructions that chage the PC.

Q:

A co-worker is rude to customers, what would you do?

Answer

That would depend on what kind of a rapport I had with him. If I felt comfortable, I would probably mention that being rude is probably going to be bad for him in the long run, since unhappy customers reflect badly on the sales associate. Otherwise, I would mention to the supervisor what I had witnessed, and let him handle it.
