Q. P. Code:

(Time: hours)

[Marks: 75] Please check whether you have got the right question paper.

N. B.: (1) All questions are compulsory. (2) Makesuitable assumptions wherever necessary and state the assumptions made. (3) Answers to the same question must be written together. (4) Numbers to the right indicate marks. (5) Draw neat labeled diagrams wherever necessary. (6) Use of Non-programmable calculator is allowed. 1. Attempt any three of the following: 15a. What is Green IT? What are motives behind Green IT practices?

b. Write down the advantages of reusing equipment?

Advantages of reusing equipment: • There is less demand for new products and their use of virgin raw materials. • Less water and electricity is used when reuse lowers the need for the production of new products. • Less packaging is used. • Redeployed technology is available to more sectors of society, because computers and other components are often more affordable. • Less toxins are going into landfills.

c. List and explain different steps used to measure your carbon footprint. Four major steps are used to measure your carbon footprint: • Define what is included in your carbon footprint. • Set your baseline. • Track, calculate, and analyze your footprint. • Report your results to stakeholders. Explanation of each.

d. Write down different objectives of StEP Program. StEP’s prime objectives are as follows: • Optimizing the life cycle of electrical and electronic equipment by improving supply chains • Closing material loops • Reducing contamination • Increasing the utilization of resources and the reuse of equipment • Exercising concern about disparities such as the digital divide between industrializing and industrialized countries • Increasing public, scientific, and business knowledge • Developing clear policy recommendations

e. What is Basel Action Network? Write down the different functions of it. Though the nonprofit Basel Action Network (BAN) is headquartered in Seattle, Washington, it operates globally. It is a worldwide organization, focused on working with the human rights and environmental impacts of e-waste. It also works to ban waste trade and promote green, toxin-free design of consumer products.

BAN is active on a number of campaigns, including the following: • E-Waste Stewardship Project • Green Shipbreaking • Zero Mercury Campaign • Basel Ban Ratification BAN performs these broad functions:

Acts as a source of information on the waste trade for journalists, academics, and the general public.

Provides international policy advocacy. BAN is invited to participate in UN meetings and policy deliberations. BAN has also worked with the Organization of Economic Cooperation and Development (OECD) and the UN Environment Program (UNEP) Chemicals Program and Governing Council. BAN has also produced Model National Legislation on toxic waste trade for developing countries.

Conducts field research and investigations in developing countries. It also provides photographic and video documentation of e-waste trade.

Participates with NGOs around the world in campaigns to counter toxic trade.

f. Write a short note on RoHS. Whereas the WEEE Directive is designed to help manage e-waste, the European Union also took steps to reduce how much waste is actually produced. The Restriction of Hazardous Substances Directive (RoHS) was adopted in February 2003 by the European Union. The directive restricts the use of six hazardous materials in the manufacture of certain types of electronic equipment: • Lead • Mercury • Cadmium • Hexavalent chromium • Polybrominated biphenyls (PBBs) • Polybrominated diphenyl ether (PBDE) The directive sets a maximum concentration of these materials at 0.1 percent (cadmium is much lower at 0.01 percent) by weight of homogenous material. This means that the weight of these elements—if extracted from the finished product—cannot exceed the aforementioned limits.

2. Attempt any three of the following: 15a. Explain any two ways to reduce power usage.

ways to reduce power usage are

Data De-Duplication

Virtualization

Management

Bigger Drives Explaination of any two.

b. Explain any two low cost devices for checking power on workstations. Kill A Watt Calculator

c. Write a short note on MAID. MAID A massive array of idle disks (MAID) is a system that employs hundreds or thousands of hard drives for near-line data storage.



3

MAID is designed for write once, read occasionally (WORO) applications. In this model, drives are spun up only on demand to access data stored on them. Because only a small amount of the data is being accessed, these disks can be powered as needed, thus reducing the power used to run them as well as reducing the generation of heat, which in turn reduces cooling costs. MAID differs from RAID in that it has increased storage density and is much less expensive, thus saving power and the need for cooling. MAID comes with some compromises, however, such as increased latency, lower throughput, and much lower redundancy. Although a MAID solution can be slow—data access can take a few milliseconds up to 10 seconds—it is much faster than tape, which can take 60 seconds or longer to access data. Also, because large hard drives are designed for constant spinning, continual shutdown and reactivation threatens their reliability. Drives that are designed for repeated spin-up/ spin-down cycles are much more expensive. The MAID architecture really developed because of the introduction of SATA drives that are designed to be powered up and down. In a large deployment, MAID allows a dense packaging of drives, and typically only 25 percent of the disks are spinning at any given time, as illustrated in Figure 3-6. This helps with the problem of throughput. The appeal of MAID is also apparent when you consider their use in large environments. SATA drives are rated at 400,000 hours of life. If a datacenter has 1000 drives powered on all the time, a drive would fail every 18 days. Clearly this is no good, so employing a MAID system quadruples the drive’s life to 1.6 million hours.

d. What is economizer? What are its different types? Explain any one. You can save a lot of money if you are able to put Mother Nature to work for you. In a lot of the country, winter provides you with an opportunity to enhance your cooling system by using the cold outside air to cool things down. But it isn’t as simple as opening a window to accomplish this. To do so, you need to employ what is called an economizer. There are two types:

air-side economizers and

waterside economizers

e. Explain how cooling needs are calculated. Room Size Room Area BTU = Length (meters(m)) × Width (m) × 337 Windows South Window BTU = South Facing Window Length (m) × Width (m) × 870 North Window BTU = North Facing Window Length (m) × Width (m) × 165 Windows BTU = South Window(s) BTU + North Window(s) BTU People in the Room Total Occupant BTU = Number of occupants × 400 Equipment Equipment BTU = Total wattage for all equipment × 3.5 Lighting Lighting BTU = Total wattage for all lighting × 4.25 Total Cooling Requirement Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTU

3. Attempt any three of the following: 15a. What are different issues that are to be considered to know your supplier?

issues to be consider to know your supplier are

What are the supplier’s environmental values? How are they measured and enforced?

Does the supplier have an environmental management system?

Who is accountable for environmental performance? Is it just the supplier’s environmental staff, or is it all employees?

Does the supplier comply with federal, state, and local environmental laws?

Is the supplier willing to understand and work with your environmental goals?

Has the supplier made efforts to design and manufacture products with the environment in mind?

How efficient is the supplier in using resources, materials, and energy, as well as recycling and pollution prevention?

Will the supplier reclaim its products or packaging at the end of their useful lives?

b. How the issue of CO2 emission is dealt with at different levels of the decision making pyramid.

c. What are different monitoring ideas? Some monitoring ideas include: • Review each telecommuting arrangement at least once a year to make sure the criteria originally established continue to be met. • Conduct periodic site visits (at least once per year) to evaluate and ensure minimum



5

safety requirements are being met. If there are problems, the telecommuter should correct them per your agreement. • If site visits are conducted, they should be performed by a qualified safety/ergonomic specialist who can conduct an ergonomic assessment. • Get annual certificates of insurance coverage from each telecommuting employee. • In the event of an injury, the business should gather as much specific information as possible. This information will help the worker’s compensation adjuster determine whether the injury was work related. • If a third party experiences damage, the business should gather as much information as possible to determine whether the damage is work related.

d. Write down different reasons for using PDF for paperless documentation. Different reasons for using PDF for paperless documentation are :

Open format

Multiplatform

Accuracy

Security

Searchable text

e. What is intranet? What are different components that are required for building intranet? Parts four components for intranet are :

Local area network (LAN)

Web server

Web browsers on client PCs

Web page development software

f. What is EDI? Write down advantages and problems of EDI. EDI allows businesses, governmental entities, and other organizations a way to exchange entire documents. EDI allows the electronic exchange of business documents, such as purchase orders, invoices, ship notices, and over 250 others in a standardized format. Here are some of the benefits to using EDI: • Significant savings with lower EDI costs • Increased staff efficiency • A secure environment • Increased efficiency through the ability to send and receive any type of file Advantages The biggest advantage to your organization using EDI is the cost savings. EDI is more efficient than using conventional mail or fax. EDI minimizes data-entry errors, reduces labor costs, and increases the timeliness of transmitted information. Let’s consider what happens in a paper world. Typically, one company generates an order on a computer that is sent to a vendor. When the order gets to the vendor, the mailroom handles it before getting it to the sales department, which then assigns it to a clerk who types the order into the company’s own computer system. This process is very slow (you have to print the order, mail it, and wait for it to work its way through the other organization) and prone to errors (the order can be misplaced, the clerk can enter the data wrong, and so on). By using EDI, the document can be sent computer-to-computer, thus eliminating a lot of the steps where trouble can happen. EDI reduces the time it takes to receive and



6

handle the order from a few days to a few seconds. This speed not only saves labor hours, it also allows companies to better manage their inventory through speedy replenishment. What’s more, the customer can be quickly invoiced, and customer service is enhanced. Obstacles Like so many other facets of going paperless, EDI’s biggest obstacle isn’t the technology, but reengineering human work habits. Cost is another barrier to EDI. The initial expense of establishing an EDI setup can lead organizations to believe that they’re better off filling out forms. The expense comes from implementation, customizing the system, and training employees. You can make sure EDI is right for your business by figuring out if the initial costs will outweigh any future savings. For instance, a company that receives only a handful of orders every year might not reap the benefits of EDI.

4. Attempt any three of the following: 15a. Explain commercial and non-commercial refurbishing.

Noncommercial Refurbishing This field is composed mostly of nonprofit and school-based programs doing computer training. This market turns around reused computers and provides them to low-income families. More than 70 percent of noncommercial computer reuse is sent to schools. CompuMentor—an organization that helps provide PCs and other technology to low-income individuals—estimates that there are as many as 500 programs in the U.S., with an average capacity of 200 computers per year. Larger programs—such as Computers for Schools Canada; Per Scholas in New York; and Students Recycling Used Technology in Portland, Phoenix, Georgia, and Silicon Valley—provide 10,000 or more computers each year. Commercial Refurbishing You may want to take matters into your own hands and sell your computers (either individually or in lots and with or without the hard drives) on eBay. Of course, this will necessitate assignment of resources to manage the process, but it’s certainly an option. However, most major computer companies have their own divisions for repurposing computers—companies such as HP Financial Services and IBM Global Asset Recovery Services. There are also hybrids of the noncommercial and commercial programs out there. RECONNECT (www.reconnectpartnership.com, or Link 7-7) is a partnership between Dell and Goodwill Industries. Computers can be brought into Goodwill locations, Dell will refurbish them, and then the repurposed computers are sold with the proceeds going to Goodwill Industries.

b. List and explain different phases of product life cycle. 1. Terms 2. Feasibility study 3. Fact finding 4. Analysis 5. Design 6. System specification 7. Implementation and review 8. Use 9. Close

Explanation of each. c. Write down advantages and disadvantages of leasing equipment.

Advantages

Keeping your equipment up to date

Predictable monthly expenses

Low (or no) upfront costs

Staying competitive

Disadvantages

Paying more, overall

A deal is a deal

d. What is certification program? List different certification programs. Explain any one.

EPEAT

RoHS

e. Write a sort note on thin client. When considering client computers, you should also think about the advantages of using thin clients. These computers rely on the server for processing activities and are used mainly for input and output between the server. With the vast improvements in networking speed and the large shift in computers being used more as communication devices as opposed to processing devices, thin clients can make a lot of sense. Fat clients are the PCs that normally sit on your users’ desks. These machines do mostof the processing and then transfer the results of the data to the server. Thin clients usually run web browsers or remote desktop software. Advantages to using thin clients include the following:

• Lower administration costs • Security • Lower hardware costs • Efficiency • Lower energy consumption • Easy hardware failure management • Hostile environments • Ease of upgrade • Less noise • Less disposed equipment

f. Write down the steps to configure remote desktop server. 1. Select Start | Control Panel | System And Maintenance. 2. Click the Allow remote access icon from the System portion of the dialog box. 3. In the Remote Desktop portion of the dialog box are two selections you can make, based on your connection and security needs (see Figure 8-5): • Allow connections from computers running any version of Remote Desktop (less secure) • Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure). Network Level Authentication (NLA) is a new form of authentication that completes user authentication before a remote connection is made. This is a more secure method of authentication and can protect the remote computer from attacks and malware. The best choice is to select the second radio button, allowing connections only



8

with NLA-enabled computers. However, if your connecting computers don’t have NLA, or you just don’t know whether they do, you should select the first radio button. Click the Select Users button. This calls up the Remote Desktop Users dialog box in which you will add users who will be allowed to remotely access this computer. Administrative accounts are automatically given access. 5. Click Add. This calls up the Select Users dialog box, as shown in Figure 8-6. User accounts have three identifying components: object type, location, and name. If you want to locate a user account from the Remote Desktop server, make sure the “Select this object type” option is set to Users. Then type an account name in the “Enter the object names to select” box. If you wish to enter a user from another computer on an Active Directory–based LAN, click the Locations button and select the domain. Then enter the user account name. 7. Click Check Names. This gives Windows Vista a chance to enter the name in the computername\username format. 8. Click OK. The user you just indicated will be added to the list of users permitted to remotely access your Remote Desktop server. To add more users, repeat steps 6 through 8. 9. Click OK twice to exit all the dialog boxes. 10. Finally, if your Remote Desktop server is protected by a firewall, make sure the firewall allows remote connection traffic.

5. Attempt any three of the following: 15a. List and explain different tools for tracking data.

• BI Tools • Microsoft SQL Server • Microsoft PerformancePoint

b. List and explain technological components of CRM system. The technological components of your CRM system include the following:

• Database • Customer Intelligence • Business Modeling • Learning and Competency Management Systems • Analytics • Collaboration

c. Differentiate between SaaS and ASP. ASPs host applications on behalf of their clients. But ASPs generally don’t create their own applications. SaaS vendors, however, create their own applications and run them on their own. SaaS vendors also use a multitenant architecture. This means that multiple customers are running the same software, but the data is kept separate. ASPs, on the other hand, typically deploy one instance of each type of software for each customer, as illustrated next.

d. Write down SMART goals.



9

SMART Goals • Specific • Measurable • Attainable • Realistic • Timely

e. Write a short note on quantitative and qualitative review. Quantitative Reviews Quantitative reviews are the meat and potatoes of data review. This involves looking at the numbers and figuring out what they mean based on the data available. You can look at such details as the following: • Usage profiles Look for consumption peaks and valleys, and figure out how they relate to your overall operations. • Performance comparisons Use the data to compare two similar facilities in your organization. For instance, if you have branches in Spokane, Washington and Albany, New York, how do the same facilities in these branches stack up against each other? • High costs Look at the data to see where you are spending a lot of money on energy use. • What’s missing Look for any areas where you feel like you need more information, and then start collecting it. Qualitative Reviews Qualitative reviews are fuzzier than quantitative reviews. Whereas quantitative reviews focus on cold, hard numbers, qualitative reviews try to put numbers in a context to explain them. Such data can include the following: • Interviews Talk to colleagues and employees to seek informed opinions, anecdotal information, lessons learned, and in-house audits. • Review policies Look at your organizational policies and procedures to figure out what impact they are having on your energy use.

f. Write down responsibilities of CGO. Chief Green Officer It’s no secret that going green is a one-two punch of benefits—the environment benefits, and your organization benefits. However, it’s not an easy process. Many organizations, as part of their green initiatives, are adding to their C-suite by introducing a Chief Green Officer (CGO). This person has the overall responsibility to make sure the company is meeting its green goals and looking for ways to do an even better job. The CGO, ultimately, is going to be responsible for three things: • Reducing the organization’s environmental footprint • Engaging diverse stakeholders • Discovering new revenue opportunities
