...1. A family wishes to connect several devices to share an Internet connection and a Bluetooth wireless printer. They have three personal computers. One is in the same room as the printer. The other two are together in another room. In addition, they want to utilize the network for television DVR, VoIP phone, and game console. Describe what network device or devices you would recommend they purchase and explain why. Also describe the media utilized. Note, you are not required to detail the topology utilized, but thinking about this will help you to choose and justify your device choices. a. Describe what network device or devices are recommended for purpose for the given home network scenario(s). For a family who wishes to connect several devices to share and Internet connection and a Bluetooth wireless printer, I would recommend that family procure a wireless router, a modem, and a few CAT5e Ethernet cables. b. Explain the recommendations justifying why these would suit the needs for the network The family has several devices that need internet connectivity; the recommendations I made will make this happen. The modem connects to a wireless router, via plugging the broadband into the WAN port of the router, and the router will access the Internet through a unique IP address (assigned by the ISP). This will then provide local IP addresses for all of the devices connected to it, allowing the family to get Internet out to all of the devices (both wired and wireless). An...

...Foundations of Network Security Fundamentals of Network Security 2 Firewall Fundamentals 43 VPN Fundamentals 79 Network Security Threats and Issues 111 CHAPTer Fundamentals of Network Security 1 C OMPUTER NETWORK SECURITY is very complex. New threats from inside and outside networks appear constantly. Just as constantly, the security community is always developing new products and procedures to defend against threats of the past and unknowns of the future. As companies merge, people lose their jobs, new equipment comes on line, and business tasks change, people do not always do what we expect. Network security configurations that worked well yesterday, might not work quite as well tomorrow. In an ever-changing business climate, whom should you trust? Has your trust been violated? How would you even know? Who is attempting to harm your network this time? Because of these complex issues, you need to understand the essentials of network security. This chapter will introduce you to the basic elements of network security. Once you have a firm grasp of these fundamentals, you will be well equipped to put effective security measures into practice on your organization’s network. While this textbook focuses on general network security, including firewalls and virtual private networks (VPNs), many of the important basics of network security are introduced in this chapter. In Chapters 1–4, network security fundamentals, concepts...

...Using Neural Networks to Forecast Stock Market Prices Abstract This paper is a survey on the application of neural networks in forecasting stock market prices. With their ability to discover patterns in nonlinear and chaotic systems, neural networks offer the ability to predict market directions more accurately than current techniques. Common market analysis techniques such as technical analysis, fundamental analysis, and regression are discussed and compared with neural network performance. Also, the Efficient Market Hypothesis (EMH) is presented and contrasted with chaos theory and neural networks. This paper refutes the EMH based on previous neural network work. Finally, future directions for applying neural networks to the financial markets are discussed. 1 Introduction From the beginning of time it has been man’s common goal to make his life easier. The prevailing notion in society is that wealth brings comfort and luxury, so it is not surprising that there has been so much work done on ways to predict the markets. Various technical, fundamental, and statistical indicators have been proposed and used with varying results. However, no one technique or combination of techniques has been successful enough to consistently "beat the market". With the development of neural networks, researchers and investors are hoping that the market mysteries can be unraveled. This paper is a survey of current market forecasting techniques with an emphasis on why they are insufficient...

Kudler Fine Foods is a small local upscale specialty food store specializing in import and domestic products located in the three locations within the San Diego metropolitan area. Diagrams will show the current network topology. Finally, a description the standards applicable to this INDP project will be provided. Network Fundamental Characteristics and Components A network is comprised of computer hardware, cabling, network devices, and computer software, which together allows computers to communicate with each other. The network characteristics are determined by the availability, cost, reliability, security, speed, scalability, and topology. In order to understand how each component communicates and operates it’s helpful to break it down into pieces and then analyze. The diagrams below provide details of the topology of Kudler Fine Foods. Current Network Topology The current network topology used at Kudler Fine Foods is the bus topology.

...gain optimum performance of the distillation column, an effective control strategy is needed. In recent years, model based control strategies such as internal model control (IMC) and model predictive control (MPC) have been revealed as better control systems compared to the conventional method. But one of the major challenges in developing this effective control strategy is to construct a model which is utilized to describe the process under consideration. The purpose of this paper is to provide a review of the models that have been implemented in continuous distillation columns. These models are categorized under three major groups: fundamental models, which are derived from mass, energy and momentum balances of the process, empirical models, which are derived from input-output data of the process, and hybrid models which combine both the fundamental and the empirical model. The advantages and limitations of each group are discussed and compared. The review reveals a remarkable prospect of developing a nonlinear model in this research...
