...From Physical Machines to Virtual Machines Anthony V. Lear ITT Technical Institute From Physical Machines to Virtual Machines For years businesses have depended on multiple pieces of hardware, linked together and deployed with software, to connect users to the resources they need. As technology has advanced with today’s virtual software programs, we can now run another “virtual computer” on a physical client machine. With all the technology advances some people believe that virtual machines are equal to physical machines. First, let’s get some background of the physical machine (server/client) and what it has to offer a network. There are many options when it comes to the CPU, Motherboard, Memory (RAM), etc. These options include hard drives (storage), video cards, audio cards, and central processing units (CPU’s). Even though “it’s all just computation” (Nikhil, 2011, p.38) the combination of hardware can make or break the performance of a physical machine. IT professionals have to consider the needs of a network when choosing a physical machine. Depending on how it will be utilized on the network this will then elaborate on the requirements of the machine to provide the capabilities needed to perform its role on the network. For instance, if you require a file server to allocate resources such as software, programs, employee documents, etc. you will have to consider the servers hardware needs to meet this demand. The most important considerations for a file server...

...Virtual Computing: How is it Used? What are the benefits? Virtual Computing: What is it? What are the Benefits? Introduction Partitioning or dividing the resources of a single server into multiple segregated VMs is virtualization. Virtual computing allows organizations to save technical resources and money. There are various virtual computing applications which are useful to organizations. The benefits of virtual computing are achieving faster system speeds, eliminating upfront capital costs, managing corporate desktops in an efficient way and allowing reduction in power costs. Main VMs were originally in use by IBM around 1960 and were intended to leverage investments in pricy mainframe computers. “Virtualization, or technology that allows one physical PC or server to act like many separate computers, is just one of many strains on traditional software licensing. In the old days, things were simple: Each program ran once on a computer that had a single user and a single processor. Now, it is not uncommon for a program or operating system to be running multiple times on the same piece of hardware, which may be powered by multiple processors, or a single chip with multiple processing cores.” (Fried, 2006) With virtual computing allows users remote access to software applications and processes whenever it is needed. Access is gained through the internet, wireless network or network server. Through virtual computing providers, users can download and use more than one...

Research and Development 5. Summary of data/conclusion 6. References COMPUTER TECHNOLOGY AND THE EFFECT ON THE BRAIN 2 Abstract Computer technology has been around in our lives for a few century’s changing our lives for better and worse. The first set of evidence of mechanical calculating appeared in the 17th century as well as the first recorded word of computer. What we know as our modern day computer was first introduced around the 19th century. Since then computer technology has been advancing every day, making past technology obsolete very quickly. Nowadays computer technology is part of most people’s life. In the 1960’s people on average would watch around 5 hours of media compared to today’s 12 hours (Wells, 2010). Yet with all of this advanced technology how is it affecting our brains and body? In this paper I will attempt to answer these questions. COMPUTER TECHNOLOGY AND THE EFFECT ON THE BRAIN 3 Computer technology is a part of many people’s lives in this modern age. Computers have made a big impact into our lives around the 19th century. Since then they have been advancing so quickly. Before they were thought of as...

...FORD MOTOR COMPANY’S | SUPPLY CHAIN STRATEGY | | | 11/13/2012 | *The Virtual Integration Model Analysis at Ford Motor Company, to Companies like Dell* EXECUTIVE SUMMARY As director of Supply Chain Systems, I have decided to implement portions of the new supply chain strategy of Virtual Integration and strategies from companies like Dell. Although there are several key differences between the companies, Dell’s virtual integration strategy can be applied to Ford’s supply chain operation. A modification of the virtual integration system currently used by Dell could be applied to Ford’s dependent supplier base, distribution system, dealerships and divisions. Special care will need to be taken to address the unique dependency of our custom Tier 1 supplier. The management of lower tier suppliers of general or generic components would be more effectively suited by the standard procedures used by Dell. In order to adopt the Dell Model we would: · Sell direct · Mass-produce customized products · Build to order · Substitute virtual integration with suppliers for vertical integration If we at Ford could find a solution to the obstacles of virtual integration, which I will explain in detail below. It could essentially make our supply chain run smoothly with less bottlenecking, inventory, and better overall performance. Managers could overcome the complex and error-prone manual process of forecasting and procuring parts which would result in reduced...

...Conclusion………………………………………………………………………………….12-13 EXECUTIVE SUMMARY Ford Motor Company is the second largest industrial automotive corporation in the world. Their operations span over 200 countries with more than $144 billion in revenues. Over the years, its market share has been on the decline due to the entrance of foreign-based auto manufacturers. They are also faced with over industry capacity and uses minimal technology in their process. In an effort to face competition, Ford is currently reviewing Dell’s Model of virtual integration to solve their supply chain bottlenecks. However, there were fundamental issues that needed to be addressed: (1) How would the virtual integration affect the operations of Ford in areas of ordering, quality control and distribution? (2) Should Ford completely Dell’s business model or which aspects would work best for Ford? (3) Could Dell’s cycle time and lead times be replicated into Ford’s automotive infrastructure and would the current technology at Ford support this? and (4) Would virtual integration be feasible in the automotive industry given the product characteristics and industry scope? It was found that emerging technologies, globalization of foreign-based auto manufacturers and intense industry competition caused Ford’s issues. Subsequently, there were two ways Ford could handle this: adopting the whole Dell’s business model or adapting aspects of the business model. It was recommended that Ford should adapt aspects of the...

...application. It allows attacker to use multiple computers situated far away from each other to attack on single victim computer. It not only affects the services given by the application but makes it hard to stop the DOS attack. Our project concept is to implement a practical IP traceback system that will track the DOS packets to its original source. To achieve this we use Flexible Deterministic Packet Marking (FDPM). FDPM provides a defense system with the ability to find out the real sources of attacking packets that traverse through the network. While a number of other traceback schemes exist, FDPM provides innovative features to trace the source of IP packets and can obtain better tracing capability than others. We are going to simulate FDPM system in NS2 which is network simulation software and study its various advantages and disadvantages as well as its application. 2.)

...LAS VEGAS — A computer mouse that dreamed of flying might evolve into something like the Leonar3Do"bird" that can control virtual environments in 3D. The virtual reality system requires 3D glasses, the 3D bird controller and a screen equipped with three peripheral sensors. Such hardware has paved the way for newly-announced educational software under the Leonar3Do company's Vimensio brand — software that can train students to learn the names of organs in biology or model the solar system's planets. "You could put this on any computer, any laptop and have a virtual workspace environment," said Roland Manyai, director of marketing, sales and business development for Leonar3Do. The Leonar3Do technology works for more than just classroom education and games. Another company used the Vimensio software to make a driving practice simulator. A physician even used the technology to create a facial reconstruction program to plan for real-life surgeries. A demo station at the Startup Debut event of CES 2013 allowed TechNewsDaily to play with a virtual sphere. The 3D glasses tracked changes in the view of the virtual environment whenever the wearer turned his or her head. [Thomas Edison Hologram Hosts 'Gadget Graveyard' at CES] The bird controller has two buttons like a typical computer mouse. In the sphere demo, pressing the small button grabbed the entire sphere. Clicking the big button allowed for tunneling inside the sphere or creating new branches or arms extending outward from...

... Augmented Reality (AR) refers to a live view of physical real world environment whose elements are merged with augmented computer-generated images creating a mixed reality. The augmentation is typically done in real time and in semantic context with environmental elements. By using the latest AR techniques and technologies, the information about the surrounding real world becomes interactive and digitally usable (Carmigniania, 2011). For example, according to Ronald Azuma, Research at Nokia Research Centre, an AR user could see the real world and computer-generated images projected on top of that world by wearing translucent goggles (Azuma, 1997). Virtual Reality verses Augmented Reality: Most of the people may be confused with Virtual Reality (VR) and Augmented Reality (AR), a concept very similar to Augmented Reality. Here is the main difference between AR and VR. VR is a totally artificial environment that created by computers that allowed users to immerse with this environment. 3-D image is a good example of VR. However, AR is a real-time direct or indirect view of a physical real-world environment that has been augmented by adding virtual computer-generated information to it (Hermans, 2000). According to Billinghurst, director of the Human Interface Technology Laboratory in New Zealand, AR allows the users to see the real world at the same time as virtual imagery attached to real locations and object, unlike VR that draw users away from the real world and onto the screen...

...old inventory in the channel • minimize the rapid depreciation costs that mark the PC industry • operated on a negative cash conversion cycle – by receiving payment from its customers before it paid its suppliers for components • build strong, stable relationships with the large corporations and other organizations who are its core customers Issue Identification Ford continues to face increased completion from foreign competitors while operating in an industry that is experiencing significant over-capacity. In the face of the challenges presented to us, we must determine if Ford should embrace the direct business model which utilizes “virtual integration” that has driven Dell to become a clear leader in their industry. Further, if we chose to utilize “virtual integration” based on the Dell model, we will need to develop and implement significant changes in the some of our most fundamental supply chain operations. In addition, we must determine how Ford should utilize emerging information technology to transform the way we interact with supply chain members. While progress in this area will be integral should Ford choose to pursue “virtual integration”, it is also a stand-alone issue even if Ford does not choose to pursue the “virtual integration” approach to supply chain management. It is imperative our decisions regarding these issues align with Ford’s key strategic objectives of placing emphasis on shareholder value and customer responsiveness....

... FUTURE SCOPE 33 8. CONCLUSION 34 9. REFERENCES 35 1. INTRODUCTION 1.1 Abstract Virtual Classroom represents an innovative shift in the field of learning, providing rapid access to specific knowledge and information. It represents an interface between the students and a professor and provides personalized learning materials to the users. It offers a possibility to the attendees to share different resources at once and work with them as if they were at the same place where (real) resources are. In the system design, we use agents as entities that work on different tasks in the system. A set of agents of the same type is responsible for handling different users and their requests. The cooperation among agents is established through the act of exchanging messages. A wide variety of classroom techniques are being advocated to increase learning: active learning, collaboration, integration of assessment and feedback. 1.2 Problem Definition Education will change tremendously within the next few years. The significance of life-long learning and life accompanying education raises the need for new teaching and learning technologies.

...The Power of Virtual Integration: An Interview with Dell Computer's Michael Dell (Summary) Beginning in 1984 and coming up with a brave new strategic move Dell began distributing personal computers to its customers after managing to bypass the dealer channel. Virtual integration is one of the key factors that helped Dell in succeeding in the business strategically and becoming a 12 billion dollar company in just about a decade. Virtual integration captures detailed information about customers, afterwards it sends that information to suppliers periodically. This makes possible for the company to treat suppliers as inner partners and reach some level of internal coordination that does not need huge investments and an outstanding personnel. Dell segmented its customers so that 90% of its sales went towards institutions which had the largest gross margins and 70% of those customers were reportedly buying PC and Dell's other type of gadgets worth more that 1 million US Dollars a year. This segmentation was actually called "Fast-Cycle Segmentation" that differentiated large customers from the small ones. Moreover, it went through more details by putting those two types in different spots, like large customers - 1. large companies 2. midsize companies 3. government and education. This blocks were differed, too. So the company was able to get the overall picture of its customers and further manage it well by getting closer to the customers and understanding their needs properly. Dell...

...ICT 1.DEVICE DRIVER In computing, a device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device. A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent software interface. Purpose A device driver simplifies programming by acting as translator between a hardware device and the applications or operating systems that use it. Programmers can write the higher-level application code independently of whatever specific hardware the end-user is using. Physical layers communicate with specific device instances. For example, a serial port needs to handle standard communication protocols such as XON/XOFF that are common for all serial port hardware. This would be managed by a serial port logical layer. However, the physical layer needs to communicate with a particular serial port chip. 16550 UART hardware differs from PL-011. The physical layer addresses these chip-specific variations. Conventionally, OS requests go to the logical layer first. In turn, the logical layer calls...
