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:
determine cash investing and financing transactions made during the period.
Explanation:
When you analyze the statement of cash flows, you can determine and predict how will operating cash flows be in the future. E.g. a project is generating high amounts of cash, so you can predict that it will continue to do so for some time. But what you cannot predict or even compare is related to the financial and investing transactions that the company will make in the future. E.g. by analyzing a cash flow you cannot know if the company will decide to invest in other projects or will it decide to issue more stocks.

a. Calculate the employer's payroll taxes, using the following rates: state unemployment, 5.4%; federal unemployment, 0.8%.
Answer:
$9800
Explanation:
This question requires us to calculate the employer's payroll taxes
His social security tax = $110000*6.0%
= 110000x0.06
=$6600
His Medicare tax = $110000*1.5%
= 110000*0.015
= $1650
His state and federal unemployment tax = 25000 dollars
State = 25000x5.4%
= $1350
Federal = 25000x0.8%
= $200
Total employers payroll tax
$(6600+1650+1350+200)
= $9800
Answer and Explanation:
The computation is shown below:
For account receivable turnover ratio
Accounts Receivable Turnover is
= Sales ÷ Average Receivables
Beginning Accounts Receivable $21,400
Add: Sales $105,300
Less: Cash Receipts $81,300
Ending Accounts Receivable $45,400
Now
Accounts Receivable Turnover is
= $105,300 ÷ ($21,400 + $45,400) ÷ 2
= 3.15 times
Now days to sell is
= 365 ÷ 3.15 times
=116 days
