"...Paging is reliable, timely and cheap, but it is limited in the type and amount of information it can send. Wireless LANs remove the need for costly infrastructure and other hassles that come with a fixed LAN but have a limited range. Wireless WANs can cover a much larger area than wireless LANs, but are slower and more expensive. Cellular networks are the most widely used and cover the largest area, but have limitations in security and reliability."

From the Paper
"Computer security and the protection of data has been an issue since the early 1980s when computers became standard office equipment. Company sensitive information is stored on computers. Protecting the access to and integrity of this information has been a key concern for managers and computer specialists alike. The issues in data security have not changed, however the advent of the Internet has made keeping data secure more difficult. The Internet did not change the key issues, just the number of users trying to access the information. Network administrators have been facing these issues for quite some time."

Abstract
This paper produces a system analysis and design for a privately owned hospital which needs to upgrade its computerized information system. The paper discusses ways to upgrade both hardware and software throughout the clinic, establish a clinic-wide network in a single information management system and to acquire off-the-shelf software and hardware to provide data services for the clinic-wide network. The paper also shows ways in which the clinic could outsource the development of department-specific software where required and create an in-house MIS Department to manage the clinic-wide network and maintain all hardware and software. The paper includes illustrations.

From the Paper
"The utility of information technology is enhanced in health care institutions when it is implemented in network configurations because this approach allows information and resources to be shared by all elements of an institution. Expanded computerized information system capability can support cost reduction and productivity improvement initiatives within health care delivery organizations. For example, the cost and time spent on duplicate tests can be reduced if all patient treatment data are available to all clinicians in a health care delivery organization. Additional time and cost savings can be realized by automating new treatment protocols and the tools used to monitor variances from treatment standards (Murchison, 1999)."

Abstract
This paper shows how the OSI Reference model was first introduced in 1984, and was primarily designed to serve as an abstract model. However it has proved to be a practical framework and a majority of the present era's network technologies are developed based on this model. The paper discusses the seven layers which make up the OSI model - Physical Layer, Data Link Layer, Network Layer, Transport Layer, Session Layer, Presentation Layer and Application Layer.

From the Paper
"In internetworking terms, the OSI model refers to a vertical stack of layers. It is also known as Open Interconnection reference model. It is generally defined in terms of two primary layers, the upper layer and the lower layer. The upper layers of OSI model consists of software that provide certain network services like encryption, providing interface and connection management. On the other hand, the lower layers of OSI perform functions like routing, logical addressing, error correction and flow control."

"A firewall is a users best defense from invasions by outside intruders. It will protect unwanted traffic on a PC or network from an outsider. A firewall acts as a buffer between the PC or network and all external networks, especially the Internet.

"Michael Palmer defines a firewall as being a software, hardware or combination of both employed to restrict who has access to a network, to specific segments, or to certain resources.""

Abstract
In this article, the writer notes that today's society has a compulsion to transform the material world into the digital. The writer points out that there is a need, clearly prominent in the modern world, to take what exists now and restructure it into a digital form. For instance, the conversions of a teacher, chalk and blackboard to the materials displayed on a computer screen and the alteration of vinyl analogue music to the creation of the digital compact disc. The writer maintains that now, and perhaps most profoundly, society has begun to convert part of itself into a digital format through the development of virtual communities. The writer concludes that within the hope and optimism for virtual communities, there is a profusion of challenges and issues that they must face to succeed.

From the Paper
"Through the reading of studies relating to the topic, ones that were credible studies and of a qualitative nature, the extent to which the problems that virtual communities face was determined. Academic journals, online magazines and online blog columns all of a credible and relevant nature, were each used and contributed significantly to the conclusions made."
"The use of appropriately selected theory from several theorists provided the foundations from which to grasp the topic. These several theories were compared and contrasted to define what the fundamental conclusions were. The further research carried out by examining scholarly journals and other types, provided several stances on virtual communities, stances that were also compared and contrasted to determine the underlying conclusions in the studies."

Abstract
This paper talks about how to develop and maintain quality management systems. Also talks about the tools that can be used in these situations. Includes diagrams.

From the Paper
"Quality management systems are part of TQM (Total Quality Management). TQM is an approach by an organisation to provide total customer satisfaction involving all appropriate stakeholders (eg. customers, management, suppliers, employees and owners). For the most part, it is common sense. The basic concept is that you must rely on facts rather than intuition. It is generally a combination of quality and management tools aimed at increasing business and reducing losses."

Abstract
This paper discusses the secure shell (SSH) protocol. It provides a brief overview of the secure shell protocol including its origin and why it was developed and the current state of the secure shell protocol. It then focuses on the secure shell protocol itself which consists of the transport, user authentication, connection protocols and the secure shell packet configuration. A discussion of the client and server costs of secure shell including the availability of the open version of secure shell (OpenSSH) follows, with a comparison of the differences between the commercial and free versions available for downloading. It ends with a discussion of the usage of secure shell and a working practical example of how secure shell clients and servers interact with one another.

"The traditional insecure methods of connecting to networks using telnet, remote shell (RSH), or file transfer protocol (FTP), transfer commands and passwords in clear text, making them vulnerable to security attacks. These insecure protocols may now be replaced by using the SSH protocol which encrypts the clear text into an unreadable format which eliminates the risk of the message being read if captured in transmission."

"With the popularity and usage of notebook and other wireless devices such as Personal Digital Assistants (PDA's) increasing, so to has the need to connect these devices to the Internet. This has also led to a requirement for the availability and uninterrupted connection to the Internet when moving across physically network boundaries. The Mobile IP standard (RFC 3344) uses a single IP address for mobile host identification purposes even when the host moves across networks in order to achieve this."

Abstract
This paper is an objective observation of the development of the human species. It discusses the implications and effects of the principals of cybernetics based on spontaneous emergence of an international neural network of interconnectivity which is swiftly evolving to being of equivalence to a global consciousness and its exponential growth. It explores the evident implications of systemic development and growth of the internet as an international forum of connectivity and its direct effect on the species with views of its systemic principals, their interaction and the potential threat of external moderation of such information distribution.

From the Paper
"As time progresses the accessibility of the Internet is situating itself in a form of networking which allows a vaster quantity of people to 'get connected' every day and the forced moderation of the Internet has potentially dire consequences. This paper shall outlay the physical emergence of a neural network of interconnectivity, the implications of its overview and of the downward trend of the species, stipulating negative trends towards any form of inherent obligations to genetic selective retention."
