...include the effect on employees who work on that product line, the effect on community if the plant is closed, and the effect on other product lines. 4-24. In the short run, by considering fixed costs in the analysis, the manager might be including irrelevant information. If the fixed costs will be incurred whether the special order is accepted or rejected, these costs should not bear on the decision. So in the short run, the company should accept the special order if the revenue covers the differential costs, assuming that the price of the special order does not affect other business at the company. However, in the long run, all costs should be covered because fixed costs might change and thus become relevant. 4-35. Pricing Decisions 1.

...NT1330 Client-Server Networking II Name: Homework 1 Ch. 1 (70-642): Introduction to Networking Concepts Fill in the Blank: 1-10 The most widely used IP addressing scheme is IPv4. The most recent and largest address space IP addressing scheme is IPv6. To distribute IP addresses automatically, a network administrator would configure the DHCP service. The first attempt at breaking up IP address space used classful addressing to provide address ranges of differing sizes. Prior to the introduction of the Domain Name System, computers used HOST files to map human-readable named to IP addresses. A(n) Subnet Mask is used to separate the host address portion of an IP address from the network address. The subnet mask within the TCP/IP configuration is used to distinguish the network address from the host address. In dotted-decimal notation, each IPv4 address is broken up into four octets. Server computers and other systems that need to be accessed reliably by network clients should be configured with a(n) static IP address. The method of breaking up IP address space into address ranges of flexible size is called CIDR .

The existing equipment, which originally cost $25,000 and will be sold for $10,000, has been depreciated using an MACRS five-year recovery schedule and three years of depreciation has already been taken. The new equipment is expected to result in incremental before-tax net profits of $15,000 per year. The firm has a 40 percent tax rate. • • The initial outlay equals ________. The annual incremental after-tax cash flow from operations for year 1 is ________. 2. Nuff Folding Box Company, Inc. is considering purchasing a new gluing machine. The gluing machine costs $50,000 and requires installation costs of $2,500. This outlay would be partially offset by the sale of an existing gluer. The existing gluer originally cost $10,000 and is four years old. It is being depreciated under MACRS using a five-year recovery schedule and can currently be sold for $15,000.

High Speed Network Homework 1

...HW1 1. From dial-up modem to ISDN, the occupied band in the frequency domain increases by 20 times (4kHz  80 kHz), however, the bandwidth (bit rate) increases only from 56 kb/s to 128 kb/s. Briefly explain why the latter is not proportional to the former. ANS: We can tell the relationship between bandwidth and Channel capacity is not linear(proportional) relationship by examining the Shannon–Hartley theorem- , where capital C means Channel capacity and capital W means bandwidth. 2. Explain if ring topology is a good choice for WANs. ANS: WAN is a computer networking technology used to transmit data over long distances, and between different LANs, MANs. Thus, at first glance, we can say ring topology may NOT be a good choice for WAN because of the following reasons:  The communication delay of ring topology is directly proportional to number of nodes in the network. It will result in serious delay if ring topology is being chosen to implement large networks such as WAN. Moving, adding and changing the devices (or even one malfunctioning device) in ring topology can affect the whole network. Especially in the large network such as WAN, there are hundreds of thousands of routers may be under maintenance. If one or more alternate devices are not being used to replace the original one, the whole network may be shut down. Bandwidth is shared between devices, which will result in low channel capacity if the ring topology is being used in case like......

Based on the geographical map the whitepaper lays out for us, the United States receives chart topping threats in malicious code, phishing hosts, bots, and attack origin. Web based threats are increasing by the day with the endless amount of client-side vulnerabilities, attackers can focus on websites to mount additional, client side attacks. The most common web based attack in 2009 was related to malicious PDF activity, which actually accounted for almost 50% of web-based attacks. The year before that number was only at 11%. This attack got so popular because exchanging PDF files was a common day to day activity. So it wasn’t rare when you saw one in your inbox and didn’t think twice before opening it. 34% of all web based attacks happen in the United States, China is second with 7%. Some of those extremely high U.S. numbers are actually on the decline from the previous year’s report. Most of the decrease is because of increases in other countries and the Federal Trade Commission shut down a ISP that was known to distribute malicious code, among other content.

At age 62, I will start getting Social Security benefits (in two months). I can work and earn up to $12,600.00 without a reduction in SS benefits.  On an actuarial basis, a person gets the same total amount of benefits if he retires early or after age 65. You just get lower payments, but for a longer period of time.  I retired early. So my SS benefits will be like a huge, tax free, pay raise for doing nothing.  If a person does experience a benefit reduction, he really do Explain whether each of the following government activities is motivated by esn't lose benefits!!!!!!!!!

...Susan Turner Homework # 1 1. The free cash flow for 2014 is $373,584 using the EBDA model which states that EBDA = net income + depreciation + amortization. The free cash flow for 2014 is $453,584 using the EBITDA model which states that EBITDA = net income + interest + depreciation + amortization. 2. If depreciation doubled taxable income would fall and taxes would be decreased. So your net income would decrease but net cash flow would increase. 3. The quick ratio for 2014 is .9. Quick ratio = ( current assets – inventories)/ current liabilities. Quick ratio = ( 2,680,112 – 1,716,480)/ 1,039,800 = .9. The current ratio for 2014 is 2.5. Current ratio = current assets/ current liabilities 2,680,112 / 1,039,800 = 2.5. The higher the current ratio the more capable the company is of paying its obligations as it has a larger proportion of asset value relative to the value of its liabilities. The higher the quick ratio the better the company’s liquidity position. The company’s liquidity position in 2013 was very low when compared to 2012 and 2014 and against the industry average. 4. ROE = (net income / pretax profit) x ( pretax profit / EBIT) x (EBIT / sales) x (sales / assets) x (assets / equity). ROE = (253,584 / 422,640) x ( 422,640 / 502, 640) x (502,640 / 7,035,600) x (7,035,600 / 2,680,112) x (2,680,112 / 1,977,152). ROE = .6 x .8408403629 x .0714423788 x 2.6251141743 x 1.3555417085.
