Is there a difference between concurrency and paralleism. If there is how are they in common, and how do they differ?

Oksana_A [137]

Answer:

There are differences between concurrency and parallelism. They are in common about how and in which frequency the tasks are being performed and how many tasks can be performed.

Explanation:

Concurrency refers to fulfillment of a large number of tasks that are not completed in any particular order during the beginning, running and overlapping periods. When we talk about at least two or more tasks, concurrency is inherently applicable.

The parallelism does not require the existence of two tasks. In the true sense of this word, each task or subcontractor performs part or all of the tasks using the CPU's multifaceted infrastructure by identifying one nucleus for each task. Parallelism requires hardware with multiple processing units. You can get compatibility on a single-core CPU, but no parallel.

Now let us list the notable differences between concurrency and parallelism.

1) Concurrency is the time when two tasks can begin, work and complete in overlapping periods. Parallelism is the simultaneous implementation of tasks, for example, at the same time. in a multi-core processor.

2) Concurrency is an independent process, and parallelism is the simultaneous (possibly related) performance of calculations.

3) Concurrency is to deal with more than one thing. The parallel is to do more than one.

The following is the cash flow from a manufacturing plant in the next five years:

Svetllana [295]

Answer:

The sum of the present values of the stream of cash flows is $1,011,772.58

Explanation:

We need to compute the present value of the cash flows separately for each amount

The first cash flow is occurring at the end of the first year

We use the formula PV = FV/(1+i)^n

Where PV = Present Value, FV = Future value, i = Interest rate, which is the rate at which the cash flows are to be discounted and n = the year in which the cash flow occurs

Plugging the values in the formula, we get the present value for the first year

PV = 250,000/(1+0.065)^1 = 250,000/1.065 = 93,896.71= $93,896.71

The present values for the successive years are provided as under

PV = 20,000/(1+0.065)^2 = 20,000/(1.065)2 = 17,633.1857= $17,633.1857

PV = 180,000/(1+0.065)^3 =180,000/(1.065)3 = 149,012.8365= $149,013.8365

PV = 450,000/(1+0.065)^4 =450,000/(1.065)4 = 349,795.3909= $349,795.3909

PV = 550,000/(1+0.065)^5 =550,000/(1.065)5 = 401,434.4601= $401,434.4601

Adding up the present values for each of the years, we obtain the present value of the cash flow stream

93,896.71+17,633.1857+149,013.8365+349,795.3909+401,434.4601 = $1,011,773,.58 approximately (only the final answer is rounded off to two decimal points)

A marketing manager wants to build a strong relationship with the customers and to customize messages without high costs. He und

Colt1911 [192]

Answer:

Direct marketing and interactive marketing.

Explanation:

In a case of direct marketing here, they do research, identify customers, select media (TV, direct mail, internet), and create a campaign. But rather than guess whether the message worked, they track the consumer's response. How many people (and of what age, ethnic group, income level) called the number in the catalog, clicked the button on the website, or went to the store for their gift with purchase. This is because direct marketers can measure the results, they can make the next campaign even better.

While in the other hand, interactive marketing explained to be the fastest growing form of marketing where sellers do chats and explanations that comes off as convincing approach of their products to their buyers, this could be physically or online.

Answer:

a)$103.309 million initially b)$83.309 million c)240070 bonds more

Here is the complete question:

A firm with an A rating plans to issue one million units of a 10 year-4% bond with face value $100. After the financial crisis this firm is downgraded to a B rating. The yield curve increases 0.2% per year. The yield for year 1 is y1=1%, for year 2 is y2=1.2%, y3=1.4% and so on and y10=2.8%. The default spreads are given in the table below.

(a) What is the initial amount (before downgrading) the firm wants to raise?

(b) How much can this now B rated firm raise?

(c) If the firm wants to raise the planned amount, how many more bonds does it issue?

Rating Default spread

AAA 0.20%

AA 0.40%

A+ 0.60%

A 0.80%

A- 1.00%

Suppose interest rates in the UK fall. This will affect the side of the foreign exchange market and cause exchange rates to

maw [93]

A fall in the interest rates in the UK, would cause the exchange rate of the UK to decline.

<h3>What is the impact of a fall in interest rate on exchange rate?</h3>

Exchange rate is the rate at which one currency is exchanged for another currency. Interest rate is the return earned by investors for allowing business owners use their funds.

When interest rate declines, the return earned by investors would fall. This would discourage investors from investing. This would lead to a decline in the demand for the UK currency. This would depress the exchange rate.
