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.
Why estimated overhead costs (rather than actual overhead costs) are used in the costing process is explained below.
A predetermined cost is an expenditure that a company estimates ahead of time.
This cost is calculated prior to the purpose of production and includes all variable costs that affect production in a manufacturing business.
Actual overhead costs are difficult to calculate for each job, especially in a production environment with a large number of jobs.
As a result, overhead costs are allocated according to some standardized methods, which may link overhead costs to direct labor, machining time, and material used in each job.
Manufacturing overhead in a manufacturing organization refers to indirect costs that are required for production but cannot be traced back to individual products.
Machine depreciation and factory rental are two examples of manufacturing overhead costs.
Hence, computation of predetermined overhead rates is given above.

Answer:
Results are below.
Explanation:
<u>Giving the following information:</u>
Selling and administrative expense $90,000
Depreciation expense 75,000
Sales 621,000
Interest expense 46,000
Cost of goods sold 231,000
Taxes 50,000
<u>With the information listed above, we need to make an income statement following the structure below:</u>
<u></u>
Sales= 621,000
COGS= (231,000)
Gross profit= 390,000
Selling and administrative expense= (90,000)
Depreciation expense= (75,000)
Interest expense= (46,000)
Eearning before taxes (EBT)= 179,000
Taxes= (50,000)
Net operating income= 129,000
Answer:
Ans. He must save during each of the following 10 years, at the end of each year $32,452.
Explanation:
Hi, in order to find the amount of money that he should have in ten years so he can receive an annual payment of $65,156 for 25 more years (24 payments), we need to bring to present value all 24 payments to year 10. Let me show you the formula.
Where:
A= $65,156
n= 24
r= 0.08
Therefore the present value in year 10 is:
So that is our present value in year 10, or to put it in other words, our future value (if we look at it from year 0). Now we need to find the annuity (amount to save) that with account for $686,012, plus that $100,000 that he already has saved.
Every should look like this.
And we solve this equation for "A".
Best of luck.
Numerous things are excluded. For example, free of charge services are not counted such as those when family members help each other. In addition, producing things for yourself or others free of charge is also excluded. These are called non-market transactions.
