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: $17800
Explanation:
The opening balance of Retained earnings = $24,100
Net Income for the year = $19,900
Closing balance of Retained earnings = $ 26,200
The, the amount of dividends declared during the year = (opening balance) +(Net Income) -(
Closing balance)
= $ (24100+19900-26200)
= $17800

No matter which states the employee lives, the amounts withheld from each employee for social security and medicare do not vary by state. The present tax rate for social security for employers and employees is 6.2% and the present current rate of medicare is 1.45% for both the employer and employee.
Employers are typically required to withhold Social Security and Medicare taxes from an employee's paycheck and pay the employer's share of those taxes.
The Social Security Tax and the Medicare Tax have different rates, and only the Social Security tax has a salary cap. The base salary ceiling is the maximum taxable salary in the year. Determine the withholding amount for Social Security and Medicare contributions by multiplying each payment by the employee's tax rate.
