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.
Answer:
The correct answer is:
John's capital account for $35,300 (c.)
Explanation:
In the admission of a new partner, the purchase of ownership from an existing partner to a new partner is entirely a personal transaction between the existing partner and the new partner, and the extent of partner bonus (the interest sold on the original partnership amount) is acquired by the exiting partner, but this bonus is not reflected in the partnership agreement, hence the amount credited into the new partner's account is the same as that owned previously by the exiting partner, irrespective of how much the partnership ownership was sold for.
Hence, since Bobbi's partnership capital was $35,300, John's account would be credited with the same amount even if the ownership was sold for $55,900, as the bonus goes to Bobbi.

Answer:
Total cost= $24,000
Explanation:
Giving the following information:
Watson, Inc. applies overhead costs based on direct labor hours. In completing the 200 units in job #120, the company incurred $12,000 in direct materials and 500 direct labor hours at $18 per hour. The predetermined overhead rate is $6 per direct labor hour.
Total cost= direct material + direct labor + manufacturing overhead
Total cost= 12,000 + 500*18 + 6*500= $24,000
<span>As a non-management colleague, an individual does not have any immediate right to take decisions regarding the management of the company.
Therefore, if the carpet cleaners are at the door even though they had come in last week, it is better to inform the manager at the company and let the management group handle the situation.
