Introduction

Virtual. Virtual means not real or in a different state of being. In a VPN, private communication between two or more devices is achieved through a public network the Internet. Therefore, the communication is virtually but not physically there.
Private. Private means to keep something a secret from the general public. Although those two devices are communicating with each other in a public environment, there is no third party who can interrupt this communication or receive any data that is exchanged between them.
Network. A network consists of two or more devices that can freely and electronically communicate with each other via cables and wire. A VPN is a network. It can transmit information over long distances effectively and efficiently. The term VPN has been associated in the past with such remote connectivity services as the (PSTN), Public Switched Telephone Network but VPN networks have finally started to be linked with IP-based data networking. Before IP based networking corporations had expended considerable amounts of time and resources, to set up complex private networks, now commonly called Intranets. These…...

Vlan Virtual Local Area Network

...VLAN Virtual Local Area Network Introduction: A VLAN (Virtual Local Network) is a network of computers that behave as though they are connected to the same wire even though physically they may be located on different segments of the LAN. VLAN are configured through software rather than hardware. This is a big advantage to VLAN because that makes it flexible and when moved physically it can stay on the same VLAN without any hardware configuration. (http://www.webopedia.com) A VLAN has three major functions: 1. Limited the size of broadcast domains. 2. Improves network performance. 3. Provides a level of security. VLAN Switched Port and Configuration: Using a switched VLAN will allow you to create groups of logically network devices that act as though they are on their own independent network. And this includes if they share a common infrastructure with other VLANs. When you configure a VLAN, you must sign it a number ID and you also have the option of name it. The purpose of VLAN implementations is to associate ports with particular VLANs. You configure the port to forward a frame to a specific VLAN. A port can be configured to support these VLAN types: Static VLAN, Dynamic VLAN, and, Voice VLAN. (http://www.orbit-computer-solutions.com) VLAN Trunking: VLAN trunking enables the movement of traffic to different parts of the network configured in a VLAN. A trunk is a point-to-point link......

A. Analyze Whether a Keiretsu Network, a Virtual Company, a Vertical Integration, or a Different Supply Chain Strategy Should Be Adopted.

...Task 3 A. Analyze whether a Keiretsu network, a virtual company, a vertical integration, or a different supply chain strategy should be adopted. Identifying a strategy is the first step in a supply chain management strategy so that is where we start. There are many options when selecting a strategy that will work best for our market and each strategy has advantages as well as disadvantages. No matter what type of strategy we chose we will face the same main question of if we should make the parts for our product or buy them. By choosing to make them we would chose a vertical integration strategy where we buy the suppliers and take over the management of more or perhaps all of the supply chain. This strategy could lower our cost of each product but we would take on more risk in owning the additional infrastructure as well as losing flexibility in changing the product by changing suppliers. In my opinion we would only want to use this strategy if we could not find suitable suppliers that we could be assured could meet our desired quantities and quality. Another option would be a sort of hybrid called a Keiretsu network where we would help fund our suppliers or work very closely with them and in turn be part of a network that is interdependent and works together to achieve the best result for all. This seems like a clear winner but again depending on the level of commitment to the suppliers we lose flexibility and take on added risks if the supplier fails. In turn...

Virtual Office

...Virtual Office MODULE: LECTURER: STUDENT: What is Virtual Office? A Virtual Office is a workplace that is not based in one physical location but consists of employees working remotely by using information and communications technologies. Such organizations are virtual not only in the sense that they exist largely in cyberspace, but also in that they are unconstrained by the traditional barriers of time and place. A virtual office is characterized by the use of teleworkers, telecenters, mobile workers, hot-desking, and hoteling, and promotes the use of virtual teams. A virtual office can increase an organization's flexibility, cost effectiveness, and efficiency. Justification for a Virtual Office An organization’s most important asset has always been and will always be its employees. For obvious reasons, however, organizations continue to expect more from their employees each year. Companies simply cannot afford to add new resources whenever the workload increases. The result is that the demands on the average professional employee continue to increase, and indications are that this will be the case for the foreseeable future. In other words, the pressure on an employee to perform - and even outperform - has never been greater. To respond to these challenges, employees need access to business tools that allow them to do their jobs efficiently. Since much of their work depends on......

Virtual Private Network

...VPN Concepts A virtual private network (VPN) is used to transport data from a private network to another private network over a public network, such as the Internet, using encryption to keep the data confidential. In other words, a VPN is an encrypted connection between private networks over a public network, most often the Internet. VPNs provide the following services:  Confidentiality: VPNs prevent anyone in the middle of the Internet from being able to read the data. The Internet is inherently insecure as data typically crosses networks and devices under different administrative controls. Even if someone is able to intercept data at some point in the network they won’t be able to interpret it due to encryption.  Integrity: VPNs ensure that data was not modified in any way as it traversed the re Internet. Authentication: VPNs use authentication to verify that the device at the other end of VPN is a legitimate device and not an attacker impersonating a legitimate device. Cost savings - VPNs enable organizations to use the global Internet to connect remote offices and remote users to the main corporate site, thus eliminating expensive, dedicated WAN links and modem banks.    Security - VPNs provide the highest level of security by using advanced encryption and advanced authentication protocols that protect data from unauthorized access. Scalability - Because VPNs use the Internet infrastructure within ISPs and devices, it is easy to add new users.......

...Portfolio A solid network is considered one of the most critical resources in an organization, both in the private and public sector, especially with paperless transmission of business documents between companies. A solid network is the cornerstone for providing the means of transmitting data (sometimes sensitive), from one computer to another. The mission of any business is to offer a useful product, increase profits, and increase work force potential. Because of these possibilities networks may increase the organizational learning rate, which many business professionals believe is the only fundamental advantage in competition. The accuracy and speed of daily business transactions for large and small organizations are vital to their success. Unscheduled disruptions resulting in the failure to process these daily business transactions can be costly, and potentially disastrous. This essay will describe some of the possible gains, and drawbacks one may face when installing/upgrading a network. Advantages Employees want the ability to have access to all files, and services whenever needed. It is no surprise that our modern workplace is no longer bound to the office.

Virtual Network Design

...Project 2: Virtual Network Design Jaime Galena ITCS-408 Mr. Shu 12-12-14 Western Dynamics is a midsized specialty manufacturing company. They have decided that a virtualized environment would help reduce costs and provide for a smaller carbon foot print. As the company’s first step in this direction, they have decided to move two of their current physical domain controllers into a virtualized environment. The company expects this system to reduce network traffic and improve throughput between virtual servers and desktop clients. The current environment of Western Dynamics has physical machines for the Dynamic Host Control Protocol (DHCP), Domain Name Services (DNS), and Active Directory. They have recently purchased a new Quad Core computer with two Network Interface Cards (NIC) and 8 GB of RAM. This hardware should be capable of meeting the requirements necessary to run all three servers in one box. This is how the network currently looks, and how the proposed network will look like.

...2.1.1 Network History The history of computer networking is complex. It has involved many people from all over the world over the past 35 years. Presented here is a simplified view of how the Internet evolved. The processes of invention and commercialization are far more complicated, but it is helpful to look at the fundamental development. In the 1940s computers were large electromechanical devices that were prone to failure. In 1947 the invention of a semiconductor transistor opened up many possibilities for making smaller, more reliable computers. In the 1950s mainframe computers, which were run by punched card programs, began to be used by large institutions. In the late 1950s the integrated circuit that combined several, then many, and now millions, of transistors on one small piece of semiconductor was invented. Through the 1960s mainframes with terminals were commonplace, and integrated circuits were widely used. In the late 1960s and 1970s, smaller computers, called minicomputers came into existence. However, these minicomputers were still very large by modern standards. In 1977 the Apple Computer Company introduced the microcomputer, also known as the personal computer. In 1981 IBM introduced its first personal computer. The user-friendly Mac, the open-architecture IBM PC, and the further micro-miniaturization of integrated circuits led to widespread use of personal computers in homes and businesses. In the mid-1980s users with stand-alone......

...Chapter 1 Analyzing Business Goals and Constraints This chapter serves as an introduction to the rest of the book by describing top-down network design. The first section explains how to use a systematic, top-down process when designing computer networks for your customers. Depending on your job, your customers might consist of other departments within your company, those to whom you are trying to sell products, or clients of your consulting business. After describing the methodology, this chapter focuses on the first step in top-down network design: analyzing your customer’s business goals. Business goals include the capability to run network applications to meet corporate business objectives, and the need to work within business constraints, such as budgets, limited networking personnel, and tight timeframes. This chapter also covers an important business constraint that some people call the eighth layer of the Open System Interconnection (OSI) reference model: workplace politics. To ensure the success of your network design project, you should gain an understanding of any corporate politics and policies at your customer’s site that could affect your project. The chapter concludes with a checklist to help you determine if you have addressed the business issues in a network design project.

Virtual Management

...Virtual Management: A New Way to Manage Virtual Management: A New Way to Manage Technological innovation has been a driving force in the growth of e-business organizations. The e-organization growth has spawned new leadership methods and business processes aimed at maintaining competitiveness in a changing global economy. One business model attributed to the technical revolution is virtual models. This paper is intended to argue that traditional business management, methodology, and structures are failing to accommodate an ever-changing global environment, characterized by hyper-competitiveness, and the exponential increase of information systems design. The current virtual model is managed using out of date management theories, performance metrics, and technical innovations, thus creating a need to update the open systems thinking and organizational theory of the virtual model. As an open system, virtual environments are quickly becoming the new wave of business organizing. Open Systems Organizational Theory Jones (2010) defines organizational theory as “the study of how organizations function and how they affect and are affected by the environment in when they operate” (p.7). Organizational theory maintains a master relationship with organizational structure, organizational change and design, and organizational culture. Organizational structure is “the formal system of task and authority relationships that control how people coordinate their...

Monitoring Employees Private Social Networks

...Monitoring Employees Private Social Sites Are Unethical Monitoring employee’s private social network sites is unethical. The Internet has become an excellent medium to connect with the outer World. People use it to connect with other people, sharing files, entertainment and lots of other activities that are useful and beneficial. Although the Internet can be useful, it’s usage can also present a problem for employers. Most companies fear leakage of confidential information and trade secrets through e-mail or blogs. A recent survey conducted by the American Management Association and the ePolicy Institute found that 14 percent of the employees polled admitted they had sent confidential or potentially embarrassing company e-mails to outsiders(pg ). As a result, some companies have monitored their employee’s social networking site; facebook for example. So, a distinction as to why companies monitor their employee’s social sites should be made, as well, as the employee’s rights to privacy. Why do companies monitor their employee’s social networking media? The reasons managers monitor social media was revealed in a new Deloitte survey. Many businesses want to be able to monitor their employees’ social networking activity on sites such as MySpace, Facebook, and Twitter. The main problem with this idea stems from employers wanting to monitor this activity on a subordinate’s off time. Business Week reported that companies want to make sure that their......
