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 option D.
Explanation:
Increase in government spending may not lead to an expansionary effect on the economy because of the crowding-out effect. This is because increased borrowing to fund spending leads to increase in interest rates. Increased interest rate discourages investors leading to a decline in private investment. This further has an adverse effect on aggregate demand.
If the debt spending is spent on constructive work such as infrastructure, research, and development, education, etc it will create value in the future. Such spending will pose less problem in the long run. Spending on education will create human capital. Spending on infrastructure and research and development will further help in the production process.

Answer:
The correct answer is $473 (Unfavorable).
Explanation:
According to the scenario, the given data are as follows:
Actual overhead = $11,183
Budgeted Overhead = $10,710
So, we can calculate the controllable variance by using following formula:
Controllable variance = Actual overhead - Budgeted overhead
By putting the value, we get
Controllable variance = $11,183 - $10,710
= $473 ( Positive shows unfavorable)
= $473 (unfavorable)
