The virtualization concept is used at many levels and for various reasons. For example, it is used on your machine to run virtual machines, it is used in data and computing centers to provide servers and clusters, it is used in networking to provide virtual ports, …etc. Write a 250 word essay about this topic showing how virtualization can take place and the main advantages gained by virtualization in each case. Solution Virtualization means it is a combination of both software and hardware technologies to design virtual machines. The main advantage of it is we can run multiple operating system in a single platform which is used to seperate their hardware lines.Virtual machine moniter is the important and main thing in the virtualization which acts as the bridge between the control and tranmslation system. Intel virtual technology is combined with the virtualization and helps for the vmms to work more efficiently. The main advantage with the virtualization it can adopt any type of new technology that is releasing in new era and can use for multiple operating systems. If any thin wrong happens at the stage of server crashing and all it will be very difficult to reinstall and take again the work but coming to this virtualization if it was happened we can simply copy the virtual image and reinstall all what we have lost. It helps while system gets crashed and loose important information and then after if any overloading happened then it commits and maybe helpfull. It mostly secured for the data that is available and recovery options are there to get back those information what we have lost. Virtualization Technology provides a way to address virtualization funcyions and helps support for CPU and I/O virtualization and a strong VMM ecosystem. The future of enterprise IT management will be based on virtual computing. the virtualization delivers some improved troubleshooting and fault resolution..

The benefits of employing virtualization in the corporate data center are compelling – lower operating costs, better resource utilization, increased availability of critical infrastructure to name just a few. It is an apparent “no brainer” which explains why so many organizations are jumping on the bandwagon. Industry analysts estimate that between 60 and 80 percent of IT departments are actively working on server consolidation projects using virtualization. But what are the challenges for operations and security staff when it comes to management and ensuring the security of the new virtual enterprise? With new technology, complexity and invariably new management challenges generally follow. Over the last 18 months, Prism Microsystems, a leading security information and event management (SIEM) vendor, working closely with a set of early adopter customers and prospects, has been working on extending the capability of EventTracker to provide deep support for virtualization, enabling our customers to get the same level of security for the virtualized enterprise as they have for their non-virtualized enterprise. This White Paper examines the technology and management challenges that result from virtualization, and how EventTracker addresses them.

INTRODUCTION Cloud computing is being rapidly adopted across the IT industry, driven by the need to reduce the total cost of ownership of increasingly more demanding workloads. Within companies, private clouds are offering a more efficient way to manage and use private data centers. In the broader marketplace, public clouds offer the promise of buying computing capabilities based on a utility model. This utility model enables IT consumers to purchase compute resources on demand to fit current business needs and scale expenses associated with computing resources. Thus, cloud computing offers IT to be treated as an ongoing variable operating expense billed by usage rather than requiring capital expenditures that must be planned years in advance. Advantageously, operating expenses can be charged against the revenue generated by these expenses directly. In contrast, capital expenses incurred by the purchase of a system need to be paid at the time of purchase, but can only be depreciated to reduce the taxable income over the lifetime of the system. THE MAIN ATTRIBUTES OF CLOUD COMPUTING The main attributes of cloud computing are scalable, shared, on-demand computing resources delivered over the network, and pay-per-use pricing. This offers flexibility in using as few or as many IT resources as needed at any point in time. Thus, users do not need to predict future resources they might need, and to commit to capital investment in hardware. This is especially advantageous for start-ups, and small and medium businesses which might otherwise not be able to afford the IT infrastructure they need to support their growing business. At the same time, redirecting capital investment from IT infrastructure to the core business is attractive even for large and financially strong businesses. From a technical perspective, cloud computing brings the benefits of virtualization and multi-tenancy to scale-out systems. Virtualization techniques allow multiple system images to share the same hardware resources: CPU virtualization techniques create multiple virtual hardware systems, while network virtualization .

Virtualization In Software Testing

Colloquium

Hardware Support for Efficient Virtualization John Fisher-Ogden University of California, San Diego Abstract Virtual machines have been used since the 1960’s in creative ways. From multiplexing expensive mainframes to providing backwards compatibility for customers migrating to new hardware, virtualization has allowed users to maximize their usage of limited hardware resources. Despite virtual machines falling by the way-side in the 1980’s with the rise of the minicomputer,we are now seeing a revival of virtualization with virtual machines being used for security, isolation, and testing among others. With so many creative uses for virtualization, ensuring high performance for applications running in a virtual machine becomes critical. In this paper, we survey current research to- wards this end, focusing on the hardware support which enables efficient virtualization. Both Intel and AMD have incorporated explicit support for virtualization into their CPUde- signs. While this can simplify the design of a stand alone virtual machine monitor (VMM), techniques such asparavirtualization and hosted VMM’s are still quite effective in supporting virtual machines. We compare and contrast current approaches to efficient virtualization, drawing parallels to techniques developed byIBM over thirty years ago. In addition to virtualizing the CPU, we also examine techniques focused on virtualizing I/O and the memory management unit (MMU). Where relevant, we identify shortcomings in current research and provide our own thoughts on the future direction of the virtualization field. 1 Introduction The current virtualization renaissance has spurred excit- ing new research with virtual machines on both the software and the hardware side. Both Intel and AMD have incorporated explicit support for virtualization into their CPU designs. While this can simplify the design of a stand alone virtual machine monitor (VMM), techniques such asparavirtualizationand hosted VMM’s are still quite effective in supporting virtual machines. This revival in virtual machine usage is driven by many motivating factors. Untrusted applications can be safely sandboxed in a virtual machine providing added security and reliability to a system. Data and performance isolation can be provided through virtualization as well. Se- curity, reliability, and isolation are all critical components for data centers trying to maximize the usage of their hardware resources by coalescing multiple servers to run on a single physical server. Virtual machines can further increase reliability and robustness by supporting live migration from one server to another upon hardware failure. Software developers can also take advantage of virtual machines in many ways. Writing code that is portable across multiple architectures requires extensive testingon each target platform. Rather than maintaining multiple physical machines for each platform, testing can be done within a virtual machi ...

Cloud computing is a construct that allows us to access applications that actually reside at a location other than your computer, most often, this will be a distant data center. Many organizations have already started implementing these technologies to further reduce costs through improved resource utilization. Cloud Computing and virtualization enable users to use applications on internet and intranet. In Cloud computing many of the services relies heavily on virtualized hardware. Because of this, we carefully reviewed existing virtual hardware services in order to both understand how the process works and to find the service that is best suited to Cloud computing and virtualization in different situations. Keywords—Cloud Computing; Virtualization; Virtual Machine; Resource Utilisation; Data Center. I. INTRODUCTION In Cloud computing, virtualization is the basis of delivering Infrastructure as a Service (IaaS) that separates data, network, applications and machines from hardware constraints. Cloud computing is becoming popular among IT businesses due to its agile,flexible and cost effective services being offered at Software, Platform and In-frastructure level. Software as a Service (SaaS) allows users to access applications hosted by different vendors on Cloud via internet. Platform as a Service (PaaS) enables developers to code, test and deploy their applications on IaaS. In infrastructure as a Service (IaaS) model, Cloud provider’s offer services such as computing, network, storage and databases via internet. IaaS is the base of all Cloud services with PaaS and SaaS both built upon it. The primary features of IaaS are elasticity and virtualization. Virtualization enables a single system to concurrently run multiple isolated virtual machines (VMs), operating systems or multiple instances of a single operating system (OS) [1]. Cloud Suite relies heavily on virtualized hardware. Because of this, we carefully reviewed existing virtual hardware services in order to both understand how the process works and to find the service that is best suited to Cloud Suite. Virtualization is one of the oldest areas of interest in computer science. One of the most successful examples of virtualization is the Java Virtual Machine (J V M) [3]. Using the J V M allows the Java programming language to produce identical results regardless of the instruction set architecture (ISA) that is used by the hardware platform. This is because, for all intents and purpo ...

What are important abiotic factors in functioning and biotic structure of specific biomes such as tundra, rainforest, grasslands, etc. Solution An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. 1.TUNDRA ECOSYSTEM: Abiotic factors: Temperature, Precipitation (rain, hail and snow fall), Seasons (very long winters and short summers), Altitude (depends on whether it is alpine tundra or arctic tundra),Wind (strong in tundra),Permafrost. Only the top layer of soil thaws during the summer, so trees cannot grow, A lot of rocks. Biotic Factors: The biotic factors that contain the alpine tundra are living organisms that impact the growth, composition, and structure of the alpine (e.g., insects, herbivores, humans). Also vegatation and symbiotic relationships. 2.RAIN FOREST: Biotic Factors: Biotic factors are any living things in an envirnment. The tropical rainforest is full of life with apoximately 15 million different species of animals.

Identify the three main threats to biodiversity and explain how each damages diversity? Solution Answer) Three main threats to biodiversity are listed in details below; a) Deforestation and habitat loss - deforestation refers to permanently destructing the forests to make the land of forest be available for other uses. deforestation is performed by large scale burning of forests which makes a large part of unnecessary carbon emission to the environment. deforestation cause the loss in plant diversity (earlier available in those forests) as well as loss in fauna lived in those forests. b) Climate change - change in climatic conditions is a natural process which occurs at a very slow rate. but climate change due to human activities a rapid process which affect the environment in long terms. rapid climate change does not provide sufficient time for adaptation and a large part of biodiversity is lost. particularly, aquatic ecosystem is primarily affected by climate change. such climate change conditions are rising oceanic temperature, high carbon emission in environment, global warming etc. c) Overexploitation - To fulfil the requirements of rapid growing world population, often natural resources are exploited blindfold and over exploiting these resources result in loss of biodiversity such as over-harvesting lead that variety vulnerable to loss in its genetic diversity, overfishing makes that fish species vulnerable to extinction. there are other ways of overexploitation such as killing, hunting, poaching which result in losing diversity of fauna being exploited..

How is it different than the planar MOSFET described in the first 5 slides of the TFET lecture? Is the FINFET a quantum device? Give reasons why or why not. How is the nanowire device described here different than the FINFET? Why is this difference an advantage for the nanowire device? They one problem with the nanowire device is capacitive coupling. What is this and explain why it is a problem with the nanowire device? Solution 1) The FinFET technology promises to provide the deliver superior levels of scalability needed to ensure that the current progress with increased levels of integration within integrated circuits can be maintained. The FinFET offers many advantages in terms of IC processing that mean that it has been adopted as a major way forwards for incorporation within IC technology. FinFET technology has been born as a result of the relentless increase in the levels of integration. The basic tenet of Moore\'s law has held true for many years from the earliest years of integrated circuit technology. Essentially it states that the number of transistors on a given area of silicon doubles every two years. Some of the landmark chips of the relatively early integrated circuit era had a low transistor count even though they were advanced for the time. The 6800 microprocessor for example had just 5000 transistors. Todays have many orders of magnitude more. basically what is finfet?? FinFET technology takes its name from the fact that the FET structure used looks like a set of fins when viewed. The main characteristic of the FinFET is that it has a conducting channel wrapped by a thin silicon \"fin\" from which it gains its name. The thickness of the fin determines the effective channel length of the device. In terms of its structure, it typically has a vertical fin on a substrate which runs between a larger drain and source area. This protrudes vertically above the substrate as a fin. The gate orientation is at right angles to the vertical fin. And to traverse from one side of the fin to the other it wraps over the fin, enabling it to interface with three side of the fin or channel. This form of gate structure provides improved electrical control over the channel conduction and it helps reduce leakage current levels and overcomes some other short-channel effects.. The term FinFET is used somewhat generically. Sometimes it is used to describe any fin-based, multigate transistor architecture regardless of number of gates. Due to the increased emphas.

Find an attack that was successful and describe how it could have been prevented. Solution Answer: As per Computer Weekly, social engineering attacks were the most well-known hacking strategy utilized as a part of 2015. What\'s more, there\'s no indication of it backing off; in 2016 60 percent of undertakings were casualties of a social engineering attack or something to that affect. Furthermore, as per EMC, phishing attacks—the least demanding and most normal sort of social engineering attacks—brought about almost $6 billion in misfortunes in 2013 alone, spread out finished around 450,000 separate bargains. Some hurt more regrettable than others, however all brought about a sufficiently genuine shake up for security directors to recalibrate their regard for the vector, investigate their conventions, and make teaching staff a best need.

In 2011, one of these attacks bit encryption mammoth RSA and prevailing with regards to mesh hackers profitable data about the organization\'s SecurID two-factor validation coxcombs. In spite of the fact that RSA at first denied that the data could enable hackers to trade off anybody utilizing SecurID, protection temporary worker Lockheed Martin soon recognized hackers endeavoring to rupture their system utilizing stolen SecurID information. RSA retreated rapidly and consented to supplant a large portion of the disseminated security tokens. This inconvenience came down to four workers at RSA parent organization EMC. Attackers sent them email with a satirize deliver implying to be at a vocation enrollment site, with an Excel connection titled 2011 Recruitment Plan. It wasn\'t clear why the representatives would think about a spreadsheet from an outsider site, however they opened it—and a zero-day Flash adventure covered in the spreadsheet introduced indirect access to their work machines that soon exposed the keys to the kingdom. 4. 2015 Ubiquiti Networks Scam Not all hackers are searching for touchy data; here and there they simply need chilly, hard money. In 2015, Ubiquiti, a particular producer of wifi hardware and software situated in San Jose, discovered this out the most difficult way possible when their fund division was focused in an extortion conspire rotating around worker pantomime.

Hospital Management Project \"Simple Scenario\" We want to develop a comprehensive software product for XY Hospital, where several doctors are working together. There are several departments in the hospital, but a central administrationoffice is handling the patient appointment tasks. Most patients make an appointment before their visit. However, patients can walk in and can be treated if an appropriate doctor is available. On events, patients may change their visit schedule by calling. A patient who made an appointment but cannot appear should cancel his/her appointment in order to avoid a ‘no-show’ penalty. The appointment clerks in the administration office are handling all the appointments and the scheduling clerks generate ‘daily treatment schedules’ for doctors based on the appointment. The ‘daily treatment schedules’ include doctor’s name, patient’s information, nurses and treatment rooms for each treatment. Hence, doctors are seeing patients according to the daily treatment schedule. Once patients are treated by the doctors, the accounting office in the hospital is responsible for calculating the medical fee, mailing bills and receiving the payments. For the patients who do not pay for a certain period of time, the records of the patients with bad credit are sent to a collection agency. The collection agency is specialized for collecting the fee and enforcing relevant laws. In addition to the routine treatments, the hospital also provides emergency care. For an emergency care, patients do not need to make appointments. Emergency patients are seen by emergency specialized doctors, and later patients may be handed over to an appropriate doctor for further treatments. Read the simple scenario carefully for the project, and answer the following questions: Question No. 1 Briefly describe the objective of the project? [1 mark] Question No. 2 Identify all the stakeholders? [1 mark] Question No. 3 List the main functions that the project provides?

Explain a) advantage of promoting outcrossing in plants and preventing self-fertilization, explain b) two (2) neat/cool mechanisms you learned on how plants pollinate others. Make sure you provide enough detail showcasing your understanding of those processes. Explain a) advantage of dispersing seeds, andexplain b) two (2) neat/cool mechanisms you learned on how disperse their seeds. Make sure you provide enough detail showcasing your understanding of those processes. Solution Advantages of promoting outcrossing in plants and preventing self-fertilization: Adding genetic diversity to the species, It will add resistant to diseases, It will help in production of hybrid plants and flowers, which keeps the species strong, It will help in production of large number of viable seeds. There is a possibility to add new desirable characters, Yield of crop can be maintained, It helps in evolution, Undesirable characters of the plant can be eliminated. Mechanisms you learned on how plants pollinate others: 1. Imperfect (or unisexual) flowers and monoecy. The separation of the male sexual part (stamen) and the female part (pistil) into two separate flowers eliminates intrafloral pollination and favors outcrossing. In monoecy (adj. monoecious), or monoecism, both imperfect flowers are borne on the same plant.e.g. pumpkin and squash, melons 2. Imperfect flowers and dioecy. The natural occurence of individual plants bearing either staminate or pistillate flowers ensures cross-pollination. This phenomenon is called dioecy (adj. dioecious). e.g. papaya 3. Dichogamy. Opposite of homogamy, the stamen and the pistil mature at different periods. There are two main types: protandry and protogyny. In protandry, the stamens or anthers develop ahead and the pollen grains mature and are shed before the pistils or the stigma become mature and receptive. Eg: Asteraceae In protogyny, the pistils or stigma mature ahead of the stamens or anthers. e.g. Suaeda; Simpson 4. Chasmogamy. Opposite of cleistogamy, pollen is shed, the stigma becomes receptive, and pollination occurs when the flower opens The opening of the flower exposes the stigma to pollen from other flowers. 5. Hercogamy (or herkogamy). This is the spatial separation of the male (stamens) and female (stigma) sexual organs within a flower. In one type of hercogamy called heterostyly, the heights of stigmas relative to the stamens vary from flower to flower. 6. Self-sterility or self-incompatibility. Self-sterility is the inability of a plant to form functional gametes or sexual structures while self- incompatibility is a condition in which fertilization fails to occur between gametes from the same individual. In both cases, self-pollination does not form a seed and thus seeds that are formed necessarily arise from cross-pollination. ACCORDING TO CHEGG GUIDELINES WE HAVE TO ANSWER ONE QUESTION AT A TIME. POST THE REST AS SEPERATE QEUSTION, THEN I CAN HELP YOU..

Essay question: Camels must cope with hot desert environments where water is scarce and the ambient temperature is often higher than the camel\'s core body temperature. Discuss as many physics-based adaptations as you can think of with which the camel might keep from overheating while minimizing its water loss. You don\'t need to calculate anything, but be sure to discuss the relevance of all of the possible heat transfer mechanisms in play, and the physics of each adaptation. (The adaptations you list don\'t necessarily have to be ones actually used by camels, but rather ones that a camel might have used.) Solution Ectotherms maintain heat production and homeostasis by gaining heat from external environmental sources whereas endotherms maintain heat homeostasis by gaining heat from internal organs for instance in camel\'s heat producing source is liver by various enzymatic reaction due to production of ATP and converted to heat. They obtain physicas based adaptation by gaining heat from inner organs via heat of convection. T = M (metabolic heat rate) – [ R + Conductive heat + convective heat (for camle) + E] Heat Production is the process of gaining heat by metabolic process in camel\'s body Heat loss or heat transfer in camel to outside environment is under the control of the following processes – heat of conduction (W/m2) or heat of convection (W/m2). Endothermic animals such as camels are characterized by warm-blooded nature as they maintain more body temperature compared to outside environment Heat of conduction first observed in camel because camel is going to maintain constant 41C degrees of inner body temperature in desert environment in which heat transfer occurs through its body tissue followed by hair covering the body. Later, heat transfer normally resisted by the thickness of skin layers & the flow of heat is varied according to thermal conductivities. Therefore, the sum of the resistance to heat flow is equal to the total of conduction & resistance effects. Later, a “conduction heat transfer coefficient can be denoted & it is followed by transfer heat into the air where convection and radiation contribute to this step..

Describe the excel equation that you can use to measure the volumes listed in the table below. For example to measure the median value of the cells between C1 and D4 is given by \"=median(Cl:D4)\". If you use a specific range of cells explain how you chose them. If you are inexperience with excel, you may want to learn about the MIN, MAX, AVERAGE, and STDEV excel functions. Make a well formatted table that lists the volumes you measured (do not calculate these values) Solution To select a specific range of cells in excel: Click the first cell in the range, and then drag to the last cell, or hold down SHIFT while you press the arrow keys to extend the selection. You can also select the firstcell in the range, and then press F8 to extend the selection by using the arrow keys. To stop extending the selection, press F8 again. For specific table selection: Take an example of file content: If I wanted to sum the items in row 1, columns 2-4 (i.e. 11 + 12 + 13) If I were doing it by hand, I\'d type:=SUM(B1:D1) Excel equation to get the volume value for the given table: = product(A1:C1) & = product(A2:C2).
