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.

Maru [420]

Answer:

The common stockholders will receive a dividend of $100000 in 2015

Explanation:

The preferred stock is non cumulative which means that in case it does not pay dividends in a certain year, the dividends will no be accumulated and the company will not be obliged to pay these dividends in later year.

The total dividends on preferred stock per year = 6 * 25000 = $150000

The common stockholders are paid dividends after the preferred stockholders are paid.

Thus, for 2015 the common stockholders will receive a dividend of,

Common stock dividend = 250000 - 150000 = $100000

Molly Jasper and her sister, Caitlin Peters, got into the novelties business almost by accident. Molly, a talented sculptor, oft
Paladinen [302]

a. The computation of Mollycaits' operating break-even point is <em>2,473 units</em> ($4,500/$1.82).

b. The calculation of Mollycaits' EBIT on the department store order is <em>$812.40</em> ($9,500 - $8,688).

c. If department stores' price were $9.51, the EBIT will be <em>$5,387</em> ($14,075 - $8,688).

Note that for (b) and (c), the fixed cost is not considered.

d. Without paying more than $7.69, the quantity that will result in an EBIT of $3,700 is <em>4,505 units</em> ($4,500 + $3,700)/$1.82

e.  Varieties of Mollycaits = 15 with variable cost of $5.87

f. The recommendation to Molly and Caitlin with regard to pricing and varieties to offer is that, while the company can varieties to suit the needs of customers, it must ensure that it does not price them below $5.87, its operating cost.

Data and Calculations:

<u>Special contract</u>:

Units of figurines offered = 1,480

Sales value of offer = $9,500

Selling price per unit = $6.42 ($9,500/1,480)

Variable operating cost = $5.87

Contribution margin per unit = $0.55 ($6.42 - $5.97)

<u>Normal business</u>:

Estimated average price per unit = $7.69

Variable operating cost = $5.87

Contribution margin per unit based on average price = $1.82 ($7.69 - $5.87)

Fixed cost per month = $4,500

Thus, Molly and Caitlin can offer various types of figurine, but they must sell at least 2,473 units to break-even.
