The business risk which is avoidable if there is proper
precaution is letter A. Machine Breakdown. Comparing to other choices, if a
machine is used with absolute care and it is well-maintained, then possible frequent
breakdowns will be avoided. Unlike the obsolescence of fixed machinery; this means
that some fixed assets are becoming outdated and can wear-out in due time which
becomes a risk that is unavoidable. Natural calamities, on the other hand are
inevitable because humans can predict some natural disasters, but cannot
control the extent of damage caused by certain calamities to the business. Last
but not the least, is the change in management. Despite the fact that each and
everyone in the company is doing their job very well, still, those higher in
authority may choose to retire or transfer to another company.
Answer: In general, the realists believes that there's not enough bang for the buck. It says the pace and scale of cuts required by Kyoto would hurt the U.S. economy without providing significant environmental benefits. USA believes more research is needed to understand the warming trend and how technology can be used to reverse or slow global warming.
Explanation: The United States hasn't become part of the agreement because it considers a problem the fact that several major developing nations, including India and China, are not required to reduce emissions under the agreement. China is expected to overtake the United States as the world's largest producer of greenhouse gases as early as this year.
Perhaps an even bigger problem with Kyoto, however, is that scientists say that even if it is successful, it would do relatively little to slow the pace of global warming.
Answer:
Assume that a context switch takes T time. Suggest an upper bound (in terms of T) for holding a spinlock. If the spinlock is held for any longer, a mutex lock (where waiting threads are put to sleep) is a better alternative.
Explanation:
The top limit is to be twice the value of (2xT). Holding the spinlock for a longer time, it will be necessary to put the thread to sleep and get a context switch, so one process awakes the sleeping thread without the need of a second context switch.
In process synchronization, cooperating process can affect or be affected by other processes executing in the system, either directly share a logical address space, both code and data, or be allowed to share data only through files or messages, although concurrent access to shared data may result in data inconsistency. But there are several mechanisms to help the orderly execution of cooperating processes that share a logical address space, so that data consistency is kept.
