Advantages of Wireless Networking The Future of Wireless Networking
From the Paper "Wireless services are an excellent example of how just how far technology has come. Wireless networking holds the key to a new era of telecommunications, yet wireless services have been used for well over a century and are still synonymous with "radio" (ATS, 2003). The first sign of wireless technology was seen in the 19th century when Guglielmo Marconi, who is known as "the father of radio?, entered the
world of wireless technology."

Abstract Wireless communications and networks very possibly represent one of the greatest technical innovations of the twentieth century. The effect that this kind of technology is having on the development of Western society at the dawn of the twenty first society is truly fantastic, especially for those who can still remember a time before wireless networks and technology, or at least a time when they were much more a novelty than a way of life. This paper shows how wireless networks quite literally have integrated themselves with many aspects of society from work to play to communications. The paper examines some of the basic history of wireless networks, the simpler-than-it-sounds operation of these networks, and some of the applications that these networks have to offer.
Abstract The purpose of this paper is to introduce and discuss available methods to secure a network so people can access it remotely. The paper describes the network administrators? challenge of securing an enterprise network from hackers. The author writes that with software and hardware innovations, consultants and companies specializing in enterprise security, showing up practically everyday, network security is attainable.
From the Paper "When the first public access networks were installed in Berkley, California in the mid 1970s, the principle was to provide people the means to share information. Restricting access to a remote computer system or protecting it was an unimaginable concept."
Abstract This paper describes what is involved in the field of network management. The paper explains that it entails safeguarding the network from threats of unauthorized users, an emphasis on avoiding bottlenecks in the network, making sure network resources are available to the users and attendance to hardware and software failures. The paper also looks at one of the primary tasks of network management, that of preserving and restoring data, and how this process is performed.
From the Paper "The common objective of enterprise-wide networking managers has been to ensure centrally managed enterprise-wide data protection for the users in a divergent environment. The enterprise visualizes its capability of preserving and restoring data is an obligation as a dial tone. However, the divergent nature of network storage environment necessitates backup solutions to cater to the requirement of an innumerable number of operating system platforms and media devices. The requirement in such lines is considered as one of the driving forces that led to devising of the standard Network Data Management Protocol -- NDMP, regarded as a scalable solution for such problems by defining a common architecture for preservation and restoration of data located on heterogeneous file servers in the enterprise. (Network Data Management Protocol Primer)"

Abstract This paper is a step-by-step guide to creating a computer network for a college campus. The author explains the purpose of the network, followed by the procedures needed to organize the creation of the network. The paper describes the equipment and facilities needed, and explains the industry standards. The paper explains the need for a UPS, explains cable considerations, and explains the standards for creating an easily usable network, as well as one which can be maintained by non-certified personnel.
From the Paper "In summary, ensure that a well thought out plan designed around every technology is incorporated to develop a suitable intelligent building network. The cabling task can be daunting if a person doesn't know how to reduce the time and money it requires to provide cabling to a vast network. There is always an efficient alternative available which have been discussed in the paper. If they are kept in view, a person can develop a huge network economically and efficiently in a short time. "
Abstract This paper discusses network security and the threat posed by a company's internal employees to network security. The paper explains that while it is recognized that external threats such as hackers, worms, viruses and various email attack strategies pose a significant and often expenses security risk, protecting against these risks is a known quantity. On the other hand, the paper relates that protecting against employee network security risks is more problematic and often requires human resource initiatives in tandem with network security applications and protocols.
From the Paper "There are essentially two separate schools of thought regarding the character of network security vis-a-vis the threat to security posed by employees. On the one hand there is the opinion that employees pose the greatest threat to network security due to their network access and often unrestrained Internet use. Conversely, there is the school of thought that, while admitting that employees pose a considerable security risk, believe that external threats such as hackers and viruses pose a far greater risk. The industry consensus seems to be that both issues need to be addressed but that employee security risks is perhaps the most difficult to prevent since 84% of security violations across a network occur when employees, either intentionally or inadvertently, send proprietary data outside of a company's network."
The paper examines the phenomena and rapid spread of social networking sites and blogs, their influence on users and the responsibility this puts on site owners and users.
Abstract Over the past few years we have witnessed an explosion in the number of social networking sites in all shapes and forms as well as an even greater spread in the use of blogs as a means of information dissemination and communication. This paper examines the development of the social networking and blog culture and discusses the responsibility that networking site owners and blog publishers have both to themselves and the larger world of internet users. The author examines the case for free speech and freedom of expression that social networking and blogging is built around as opposed to the need for social responsibility and the preservation of picture and privacy. The work has one drawing and extensive links to internet sites.
From the Paper "Now that the technological era is booming, and far from reaching its pinnacle any time in the near future, the computer and items pertaining to the industry reign supreme. This 'regime of the networks' will last because their uses are vastly increasing to a seemingly infinite number. Moreover, whether information is hoarded, transferred, or rubbed out, it can all be done through such networks. Among the various types, social networks are best suited for examining the responsibilities of users and providers. Although there is a substantially tactile presence when being 'social' in its truest form, social networks allow the physical manipulations of data, info, or even programs in the vast 'cyber space' to make a presence of intangible character, something nevertheless palpable in mindset. This is important to comprehend because based on this assumption, regulations, prohibitions, and responsibilities are developed to help maintain an ethical and legal area. These responsibilities and regulations help in preventing the constant cleansing and upkeep by the provider of such areas based on nonsensical, irresponsible acts on both ends. However, these responsibilities should be balanced, where both sides' obligations are abecedarian enough to actually make an effect."

Abstract This paper describes the design of a basic local area network that would be useful in a wide variety of businesses and possibly educational settings for a cost of approximately $200,000. This system is designed both to meet current needs of a business that wishes to run efficiently and to be able to interact with other businesses also running at acceptably high efficiency levels for a company with high-tech aspirations. In order to work, the system needs to show flexibility in order to expand with growing business needs and volume for at least several years before any new substantial investment is made in hardware or new software. In order to demonstrate the feasibility, the author gives us an overview, definition and background about a basic local area network. The feasibility of the network's success is analysed, and its potential for successful integration into an actual business is evaluated.
From the Paper "However, at the same time, no network designer should make the mistake of providing too few of a number of peripherals like printers because doing so limits the efficiency of workers and tends to produce a great deal of frustration in the office. Workers sitting around waiting to print out a needed job are not only workers being paid not to work, but they are also workers being paid to be frustrated, which is most certainly not the ideal situation in any way. Perhaps a good standard rule for the network designer would be to estimate the number of peripherals needed and then for every 20-25 people who will be using the network to add one peripheral. The added cost in initial equipment expenditure will be paid back by the fact that workers will be able to be more efficient. This will also allow for workers to continue to be productive when a device breaks down (as of course will happen) because there will be other machines within the network already linked to provide those needed services (Derfler 68)."
Abstract This paper examines the business benefits of virtual private networks and compares them to expense of dedicated circuits. It describes the technical application and its solutions for connectivity. The paper states that the purpose of the virtual private network is also to create "trust relationships" through the use of a low cost public network without sacrificing the security of the organization
From the Paper "The Internet application that I would encourage the organization to implement would be a virtual private network. This will provide the organization with the opportunity to save huge amounts of money because the application uses inexpensive public networks to create a private network. VPN's allow an organization to make use of the low cost of public networks as an alternative to purchasing costly dedicated circuits. Another opportunity that this application will provide is a secure way for remote offices and headquarters to be connected and to share information. In addition this application is very user accessible and allows employees access to the network from their homes? or other remote sites."

Abstract This paper begins by explaining this unique technology, which has already started altering the way people think about artificial intelligence. It says that this computer provides a unique computing architecture whose potential has only begun to be tapped. Artificial neural networks take their name from the networks of nerve cells in the brain, which they are trying to imitate.
From the Paper "The more time scientists spend designing computers, the more they marvel at the human brain. Tasks that stump the most advanced supercomputer such as recognizing a face or reading a handwritten note are child's play for the 3-lb. organ. This is because the brain operates through a serried of interconnected neural networks made up of dendrites, rather than the typical computer program that performs operations through elaborate series of individual steps. Unlike any conventional computer, the brain can learn from its mistakes, and forge new network connections. Researchers have tried for years to program computers to mimic the brain's abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more like a person and less like an overgrown calculator; it must be built more like a brain, which distributes information across a vast interconnected web of nerve cells, or neurons."
Abstract This paper consists of a brief introduction of networking and TCP/IP and Internet working. Also discussed are risk management, network threats, firewalls, and special- purpose network devices. The paper provides a better insight into the general aspects of security and allows the reader to get a better understanding of how to reduce and manage risk factors at the workplace and at home.
From the Paper "It is very difficult to actually be able to estimate security as to what level of risk in terms of security is acceptable. The most important factor to be able to decide as to what security actually implies to an organization. After deciding upon this we can analyze the rest of the factors in connection to the policies of the network. The various projects and systems can also be broken down in to their components and after this it also become much easier to decide as to the proposed will actually conflict with the security practices and policies. A lot of people give a huge amount of money for security but do not like it to interfere in the business. It is very essential that we build system and networks in a manner that the user is not affected with the security system that is present around him. Individual users who do not like the over restrictive security and system policies will think of ways of getting around it. It is essential to get the opinion of such individuals and let them know as to why what is being done is done so. (Network Security and web services Deployment)"
