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.

Explanation:
Giving the following information:
Assume Pinkie started the year with 100 containers of ink (average cost of $ 9.10 each, FIFO cost of $ 8.60 each, LIFO cost of $ 8.00 each).
During the year, the company purchased 800 containers of ink at $10.00 and sold 600 units for $21.75 each. Pinkie paid operating expenses throughout the year, a total of $ 5,000.
FIFO:
Sales= 600*21.75= 13,050
COGS= (100*8.60 + 500*10)= 5860
Gross profit= 7190
Operating expense= 5000
Net operating profit= $2,190
LIFO:
Sales= 13,050
COGS= (600*10)= 6000
Gross profit= 7,050
Operating expense= 5000
Net operating profit= $2,050
Average-cost
Sales= 13,050
COGS= [(9.10+10)/2]*600= 5730
Gross profit= 7,320
Operating expense= 5000
Net operating profit= $2,320
Answer:
Following are the organizational characteristics that explain the 100-year longevity of a company:
Explanation:
Selling Necessity Goods
Many of companies provide such goods and services which are essential for our everyday activities. Hence, people tend to buy from these companies as it is their routine to do so.
Laser-Sharp Customer Focus
These companies have always focused on the ever changing needs and demands of the customers and have worked accordingly. Hence their focus on customer service is the key to their success.
Willingness to Chart New Territory
Since customer needs are always evolving, all organizations celebrating centennials have taken significant gambles in order to expand their offerings. Steelcase, for instance, began as a furniture company but has recognized that the way people work has changed.
Ongoing Community Relationships
Long-lasting organizations also make their mark by giving back to the communities in which they’ve thrived. The GSUSA estimates that its members complete more than 75 million hours of community service annually.
These organizations have achieved so much because they have adapted their strategies to a changing world, and because they are always looking for ways to improve people’s lives. It is these traits that position them well no matter what the future holds.
