...An operating system, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer would be useless. As computers have progressed and developed so have the many different operating systems. We will talk about the different operating systems and how they compare and contrast as far as their security and memory management. The first operating system we will compare and contrast is Windows Vista and the security features it offers. Windows Vista is an upgrade to Microsoft Windows XP and Windows 2000. When it comes to security and Windows vista, Windows Vista can help protect your PC and the people that use it by providing safety and many security features. One feature includes Bit Locker Drive Encryption. Bit Locker Drive Encryption is a security feature that provides data protection by encrypting all the data that is stored on the Windows Operating System. Windows Vista also has Encrypting File system available which is similar to Bit Locker Drive Encryption except that it is for user level file and folder encryption. Drive Encryption is good if you have two users sharing the same computer. Another security feature for Windows Vista is Parental Controls. Parental Controls are to protect your children and for restricting them to certain areas of your computer. Parental Controls help parents determine which games their children can play or which...

...File Systems and Windows Versions Comparison and Contrast Joel D. Belew University of Phoenix There are many different versions of Windows operating systems and software. Each has a different ability or use as the technology for each was increased and or changed over time as each was used. Some of the major versions of Windows include: Windows Server 2003, Windows Server 2008, Windows 200, Windows XP, Windows Vista, and Windows 7. These versions all have some similarities as well as differences that make them separate from each other. The following paragraphs will lists some of the comparisons and contrasts that make each individually different. The common file system used for most all of Windows versions including: Windows NT, Windows 2000, Windows XP, and all successors to these versions are the New Technology File System or NTFS. This file system has taken the place of the File Allocation Table or FAT file system and the High Performance File System or HPFS. The NTFS allows for better metadata support as well as advanced data sets giving the versions more performance, space, and security extensions. These upgrades have become the standard for today’s use until the release of better technology. The current version of NTFS commonly used is an on-disk format v3.1 created for use with Windows XP. This version is included with all versions of Windows operating systems following XP. Other filing systems that were used during releases of NTFS include: FAT, A FAT file...

...LINUX Costs of Acquisition and Support – A Comparison August 2005 PREPARED FOR Microsoft TABLE OF CONTENTS Main Findings.................................................... 1 Executive Summary ......................................... 2 Analysis ............................................................. 2 License and Subscription Considerations Support Considerations The Total Solution Viewpoint 2 3 6 Main Findings 1. Microsoft’s Windows Server 2003 enterprise license and support costs are competitive with Red Hat Enterprise Linux. 2. The two companies’ different approaches to enterprise licensing and support, and the fact that investments of this magnitude tend to involve longer-term commitments, means that the best pricing comparisons should be based on a period of ownership (three to six years), rather than on just initial acquisition charges. 3. Support is integral to both companies’ solutions and Microsoft’s separate support and license fee structures, in contrast with Red Hat's combined subscription and support offerings, can give a Microsoft solution a significant pricing advantage over a Red Hat solution.

...Compare and Contrast name POS 355 date instructor Compare and Contrast This paper will give a comparison and contrast between and mainframes and Personal Computers. Over the years personal computers and mainframes have made huge advances over the years. Personal computers are just what they are called personal computers while mainframes are used for large businesses and organizations for multiple users. Both have had enormous changes over the years, dumb terminals have evolved into what we now call personal computers. Mainframes started out as very large machines, they use to occupy anywhere from 2,000 to 10,000 square feet sometimes more. They are now around the size of other types of commercial-use computers. We have personal computers because of mainframes they are part main frame and part dumb terminal. This is why mainframes and personal computers have the similarities that they do. Both mainframes and personal computers have one or more central processor units, I/O systems, busses, and memory. They are both systems that are IBM-based and they are both built using similar hardware. The calculations and actions that they perform are the same. The physical design has stayed the same for many years now. They both have memory, a display, a processor, storage, and an operating system. In the past mainframes could access more space than a personal computer making them a very important tool. Mainframes were able to retrieve many times more memory than...

...IFRS and GAAP Valeria Torres Acc/290 05/02/16 Comfort Chevannes What are the main diffrences between IFRS and GAAP International Accounting Financial Reporting Standards AKA IFRS and Generally Accepted Accounting Principles AKA GAAP are two financial reported systems that govern and principles to the accounting world. Both systems require specific financial documents and have specific standards to follow in terms of accounting for inventory and how they define assets. What will be further discussed will be key diffrences in the two financial accounting reporting systems. IFRS 2-1: In what ways does the format of a statement of financial or position under IFRS often differ from a balance sheet presented under GAAP? IFRS and GAAP’s difference in the format of financial position on the balance sheet is the order in which liquidity is reported. In the balance sheet under GAAP the degree of liquidity is taken highly into consideration, meaning that cash under currents assets is the first to be recorded followed by longterm asstes, liabilities and then share and stock holders equity. IFRS on the other hand doesn’t require any type of recording order. So it can start with Liabilities, and work its way down the line to current assets, cash. IFRS 2-2: Do the IFRS and GAAP conceptual frameworks differ in terms of the objective of financial reporting?

...achieving an operating profit in FY07, the first time since FY01. JAVA recorded three consecutive quarters of positive EPS in FY07 and is now targeting an operating margin of at least 10% in FY09. However, underlying this growth is a scenario that bristles with complexities, and not everything is as rosy as it seems. For instance, growth appears anemic—sales are expected to rise in low single digits this quarter. And it’s not yet clear whether JAVA is making new money through open source or simply finding new ways to save money. All eyes are now on Jonathan I. Schwartz, who took over as CEO of JAVA from Scott McNealy in Apr-06; justifiably so, because Schwartz is not merely seeking to turn around operations by paring payrolls, reducing headcount, and restructuring. He has set out to redefine the way a company can do business in the new Web age. If Schwartz can reestablish Java as a credible trendsetter, it would make for one of the Valley’s more spectacular comebacks. We analyze whether Schwartz’s pronouncements of growth objectives match JAVA’s performance across sectors and whether the targets can be achieved by cost containment rather than revenue growth. We set out to gauge whether this turnaround is a temporary blip or a true resurgence. Management change and new objectives When Schwartz took over as CEO in FY06, he outlined five broad objectives: 1. FY07 revenue growth in low-to-mid single digits 2. FY07 gross margin of around 43% 3. Operating margin of at least...

There is also a description of some issues the SEC must consider in order to adopt IFRS in the United States as well as a comparison of the rules regarding revenue recognition under IFRS versus GAAP. There is an explanation of the definitions Under IFRS for revenues and expenses, as well as an explanation of the competitive implications (both pros and cons) of Sarbanes-Oxley Act (SOX). Questions IFRS 2-1: In what ways does the format of a statement of financial position under IFRS often differ from a balance sheet presented under GAAP? The main difference between the formatting of IFRS and GAAP statement of financial of position and a GAAP balance sheet is the ordering of liquidity.

...Open Source vs. Closed Source Open source and Closed source, two topics that have become quite the buzz in the world Information Technology (IT). Chances are, if you work in IT, you will eventually be faced with having to decide on witch of these technologies you will have to go with when planning for an upgrade or new IT system implementation. Before choosing which technology to go with we as IT professionals must first understand the difference between the two as well as carefully weight the benefits and disadvantages of each solution. An Open Source Operating system refers to software whose source code, the medium in which programmers create and modify software, is freely available on the Internet; whereas, by contrast the closed source code for proprietary commercial software is usually a closely guarded secret and is not available to the public. (Crooke, 2012) Notable open source operating systems include Android and Linux. Notable Closed source OS include Apple iOS. The two major benefit of using an Open source software is that the software is distributed under a variety of licensing terms, but almost all have two things in common: the software can be used without paying a license fee, and anyone can modify the software to add capabilities not envisaged by its originators. (Crooke, 2012) These benefit help to lower cost of products as well as offer customers the ability to customize platforms as needed to meeting business needs. The disadvantage that is associated...

...Comparison and Contrast between Ultrabooks and Tablets Thesis Statement Ultrabook PCs are superior to Tablet PCs based on comparison of market positioning, design concept, growth rate in sales and research and development of manufacturer. Introduction In modern time, computers have become an essential tool to assist people in dealing with their complicate lives and satisfying their fast footstep. To conveniently carry computers and efficiently use them in daily work, increasingly people pursue portability, utility and fashion. So Tablets and Ultrabooks are“born” at the right moment. In order to promote laptops, many manufacturers always campaign on the slogan "it is an Ultrabook" on the margins of Ultrabooks. So in 2011, Intel corporation conceived an Ultrabook and defined as “an Ultrabook ” is a mini notebook computer designed to provide similar or superior computing functionality as that of a standard laptop but with less size, weight and an extended battery life”. Now, the term has extended to refer to a new category of notebook computers that sits somewhere between lightweight laptops and Tablets. However, Tablets and Ultrabooks are obviously different. A Tablet computer, or simply Tablet, is a mobile computer with display, circuitry and battery in a single unit. We know that Tablets are often equipped with sensors, including cameras, microphones and touchscreens, and with finger or stylus gestures replacing computer mouse and keyboard. In this thesis, I will explain...
