Abstract
This paper considers various aspects of distributed file systems, including implementation and scalability.
From the Paper
"Today's computer systems are highly dependent on distributed file systems. Although today's computer systems have storage capacity far greater than at any time in the past and although that storage is less expensive than at any time previous there is so much data to be stored, referenced and accessed that without distributed file systems it would be nearly impossible for today's systems to be as widespread as they are. Distributed file systems offer greater flexibility to companies and organizations by making it possible ..."

Abstract
This paper examines how Windows 2000, XP and Server 2003, collectively referred to as Windows NT 5.x support a limited number of file systems, each having a specific purpose. It looks at how Windows NT 5.x provides all the basic file system services expected of a modern operating system through its small set of general-purpose and specialized file systems.
From the Paper
"NTFS is a modern general-purpose file system. It supports journaling, in order to more quickly restore the file system to a consistent state after an incorrect shutdown. (AlistairMcMillan, et. al. 2005) NTFS has robust metadata support, with a built-in ability to add new file attributes, which Microsoft has used to add features such as DFS indexing, which was not originally intended as a feature of NTFS. One use of this metadata is the file ownership and permissions model used on Windows NT 5.x. File ownership and access control permissions are stored as file metadata. These access control lists, or ACLs can express a sophisticated set of permissions, based on listing which users and groups of users have permission to perform certain actions on a file. Available actions include reading the data in the file, modifying the file and executing it, if it is a program. NTFS has alternate data streams to support multi-part files such as the split resource fork and data fork used on Mac OS."

Abstract
This proposal discusses the pervasive adoption of virtual private networks (VPNs) as requiring more organizations to integrate systems, data warehouses and compute-intensive processes together to ensure remote employees, managers, suppliers, and customers have access to the information they need. In many IT architectures the need to integrate with the Windows NTFS Version 3.0, also called the Encrypting File System (EFS) and VPN architectures is becoming commonplace. The intent of this research proposal evaluates the performance of Windows NT-based servers running the NTFS 3.0 with full EFS functionality enabled in a series of benchmarks that replicate actual employee, supplier, and customer work processes. The NetIO and NAS performance benchmarks are used as the basis of comparison.

Technical Comparative Analysis of IPSEC vs. SSL-based VPN
Summary
From the Paper
"Comparing the protocols relative to the topologies supported security models used for both session authentication and confidentiality are critical to the security of both IPSEC and SSL-based VPNs. In addition, the major differences in how Quality of Service (QoS) and Service Level Agreements (SLAs) are managed are also highly dependent on the configuration of EFS with both IPSEC and SSL protocols in a VPN environment. The scalability aspects of each protocol are also compared in Table 1 below, in addition to both site-to-site and remote access support from a management perspective is included.
"Provisioning and service deployment as part of VPN management is also included in Table 1. Differences in VPN Client support and transparency are also profiled. Table 1, Technical Analysis of Differences between IPSec and SSL highlight the differences on each of these technical dimensions. The key differences center on scalability and transparency to the user. Scalability of SSL is entirely dependent on the underlying Internet traffic, while in IPSec, through optimized routing of point-to-point connections including the use of algorithms are used to maximize speed."

Abstract
This paper looks at how sophisticated computer systems are a necessary cost that corporations are finding themselves faced with in order to maintain control and reliability of their computer systems. Without them accountants will be unable to appropriately balance and file reports. The paper discusses how, in order to reduce this, some corporations have put account managers in place to police their customers when checks are received and bills issued. This puts an additional level of checks and balances in place to try to eliminate inaccurate postings. The paper concludes that, although mistakes will occur even with data analysis systems and security protocols in place, the fact is that the best companies can hope for is to reduce inaccuracies.

Conclusion
From the Paper
"In today's market place data is being channeled into networks through user screens that are more than likely customers' computers. They submit their orders via their own computer systems while inadvertently place security responsibilities to others. With the Internet, online ordering is putting the customer in control of what he needs and when he needs it. This puts additional pressures on companies to not only protect the data that they currently have within the walls of their servers but to also maintain some degree or order in the process flow of data from a customer. While doing this it must also be realized that customer computers must be preserved from receiving corrupt or virus laden files from the company systems when they are attached to the corporate website or host providers.

Operating Systems (OS), 2004.
This paper discusses extensively the design and function of an operating system (OS).
6,365 words (approx. 25.5 pages), 49 sources, MLA, $ 147.95
»
Click here to show/hide summary
Abstract
This paper explains that operating systems are primarily resource managers; the main resource they manage is computer hardware in the form of processors, storage, input/output devices, communication devices, and data. The author points out that it is important to understand that an operating system occupies the lower layer of system software; hence, it is always closest to the physical machine and, therefore, effectively manages both hardware and software by making use of its kernel. The paper stresses that security plays a fundamental role in an operating system, since it protects the OS from being destroyed or invaded.

Conclusion
From the Paper
"A process in a multiprogramming system is said to be in a state of deadlock if it is waiting for a particular event that will not occur. ?In a system, deadlock, one or more processes are deadlocked?. In multi programmed computing systems, resource sharing is one of the primary goals of the operating system. When resources are shared among a population if users, each of whom maintains exclusive control over particular resources allocated to that user, it is possible for deadlocks to develop in which the processes of some users will never be able to finish."

Abstract
This paper examines the numerous uses for XML type formatting as it pertains to the storing or filing of data in an information system. The writer contends and explains that XML is considered a standard method for storing information and is deemed the ideal choice for use in a system that requires some form of communication via an arbitrary or unknown program. This paper discusses the manner in which computer programmers as well as Unix developers make use of XML while also comparing its effectiveness and functionality to Unix text formats, which are preferred by various experts in the field. This paper also explores how XML is used in various forms of online communication such as instant messaging.
From the Paper
"One of the easiest ways for a programmer to save data to a file or stream it across a network is to simply dump the data structures, unaltered from memory. Such data dumps are easy for the program that created them to read, and quite difficult for anything else. This has traditionally been a popular technique among Windows developers; Unix developers have traditionally preferred text-based file formats. (Raymond 2003) Traditional Unix text formats, while easy to parse, even without knowing the internal details of the program that created them are not formally standardized. Generally, a program must by specifically designed to read and write another program's file or stream format. XML provides a generic tool for doing so, often supported by an external library. The XML syntax should look familiar to any Lisp programmer; Lisp property lists have exactly the same structure as XML documents, and have served the same purpose since long before XML was intented."

Part 4: Research Objectives and Methodology
From the Paper
"Order broker (integration framework)--In addition to the reliable and scalable messaging found in leading Enterprise Application Integration (EAI) systems, the systems must be specialized to deal with the way orders are decomposed and processed. First, it must have a universal order object that has several key attributes: order line independence, ability to translate a single order and order lines into all of the required activities including the generation of purchase orders, service orders, manufacturing order and distribution orders, and ability to define dependencies between the individual order lines. The order definition is then connected to the order broker, which can be based on a standard EAI system or a vendor's own messaging layer that prepares the instructions for the various parties and defines the format of the business documents and communication methods."

Abstract
This paper considers heterogenity, openness, scalability, security, concurrency, failure handling and transparency in distributed databases. It defines "distributed databases." The paper provides an analysis of its benefits and looks at productivity gains and security issues.
From the Paper
"As its name suggests a distributed database is a collection of data that is located in several different physical locations-that is distributed over several resources-while operating as a single logical database. This provides system managers the ability to distribute the database over multiple systems depending on system resources and to use either local or wide area networks to access the data. When this type of database configuration is used there are obviously many different factors that need to be taken into account ..."

From the Paper
"Order management functionality was first added to manufacturing resource planning (MRP II) systems in the form of order entry modules. As its name indicates, this module was designed to enter customer demand into the system to close the materials requirements planning (MRP) netting loop. Generally, order entry modules were designed for manufacturing, not for customer service support. As a result, most early order entry modules were cumbersome. These modules enforced a rigid process that required order numbers, customer IDs, item numbers, address IDs, remit-to addresses, etc. all to be predefined before an order could be entered."

64-Bit Operating Systems, 2004.
This paper discusses the 64-bit architecture of operating systems, which permits expanded memory and processing speeds in computers.
1,825 words (approx. 7.3 pages), 3 sources, APA, $ 58.95
»
Click here to show/hide summary
Abstract
This paper explains that a 64-bit processor is simply one that can work with numbers that are up to 64 bits long instead of 32 bits long as in a 32-bit processor. The author points out that computers with 64-bit processors can run database and other business programs faster, manage larger data files and databases, allow more concurrent users and applications to access data, and reduce software-licensing fees. The paper reports that a 64-bit processor can work on extremely large data sets very efficiently, at least in theory; however, modern 32-bit processors can now work on multiple 32-bit instructions simultaneously.
Table of Contents
Introduction
Understanding the Differences between 32-Bit and 64-Bit
How 64-Bit Processors Work
Advantages and Disadvantages
Conclusion
From the Paper
"Performance benefits will increase when software is written specifically to take advantage of 64-bit processors. In this case, a 64-bit processor can perform an instruction on a larger chunk of data in one operation, but again, this is only of benefit if a user is working with very large numbers, or they need very high integer precision. As such, daily office applications and games realize very little benefit or improvement from 64-bit technology."

From the Paper
"Distributed databases have the ability to be divided so that pieces of the databases can be physically located closest to where the data will be used. This enables companies to move from single-site databases built around mainframes to a network of locally placed but globally accessible databases which may even be on different classes of computers. This research examines the rise of distributed databases, their advantages and disadvantages, the environment necessary for their implementation, and an examination of how they may be used in the near future.
Data processing has evolved through three stages since 1955: decentralized, centralized, and distributed. When computers were first introduced to business, they were used by autonomous business units for specialized purposes. Networking ... '
