...applications. Memory is one of the most essential components of any computer system. No matter which operating system is being used, whether it is Windows, Linux or Mac’s OS X, the same basic requirements of memory management exist. The main requirements of memory management are protection, sharing, relocation and organization. Memory protection is necessary because it stops unauthorized programs, which may contain harmful threats, from accessing the computer’s memory. Memory sharing is when multiple programs need to access the same portion of memory. Proper management of memory ensures that this happens without hindering the performance of the system. Relocation involves moving programs between virtual memory and physical memory 2. Compare two common operating systems—Windows 8 and Fedora 20—on the difference in the memory management features. * Full access vs. No access * Linux Fedora 20: Linux has the most significant access to the source code, allowing the users to alter the code that serves as the foundation of the Linux operating system. * Windows 8: Windows 8 allows no users to the code, which is a good idea once you think about it, as some people has used that access to take advantage to make bugs and viruses. * Licensing freedom vs. licensing restrictions * Linux Fedora 20: With a Linux GPL-licensed operating system, you are free to modify that software and use and even republish or sell it. Also, with the GPL, you can...

...Ms Windows vs. Unix/Linux MS Windows vs. Unix/Linux University of Phoenix POS/420 Introduction to Unix October 20, 2008 Scott Stewart MS Windows vs. Unix/Linux The Microsoft and Linux operating systems have been long considered to be in a competition to be the best operating systems on the market. This paper will compare and contrast these operating systems to help the consumer decide which is right for his or her environment. Such subjects as; cost, market share, hardware requirements, file processing, programming capabilities, availability if application software, networking, and user interface will be examined. Cost The cost difference between running a Linux desktop / server compared to a Microsoft desktop / server is overwhelming. In all scenarios, Linux ends up being the cheaper and more “functionality rich” option. In the first scenario, let’s compare the cost difference between a Linux and Microsoft desktop. The first cost difference in this scenario is the cost of obtaining the software. A copy of most Linux distributions can be obtained for under $60 dollars, and free if it is downloaded from such sites as www.linuxiso.com. A Microsoft desktop is not so cheap however; the initial cost of purchasing a full copy of Windows Vista is currently $319.95, a much larger cost than that of Linux desktop. Functionality wise, both the Linux and Microsoft desktops provide the basic needs of the “home user,” however, such additional features as an Office...

...access to the source code is probably the single most significant difference between Linux and Windows. The fact that Linux belongs to the GNU Public License ensures that users (of all sorts) can access (and alter) the code to the very kernel that serves as the foundation of the Linux operating system. You want to peer at the Windows code? Good luck. Unless you are a member of a very select (and elite, to many) group, you will never lay eyes on code making up the Windows operating system. You can look at this from both sides of the fence. Some say giving the public access to the code opens the operating system (and the software that runs on top of it) to malicious developers who will take advantage of any weakness they find. Others say that having full access to the code helps bring about faster improvements and bug fixes to keep those malicious developers from being able to bring the system down. I have, on occasion, dipped into the code of one Linux application or another, and when all was said and done, was happy with the results. Could I have done that with a closed-source Windows application? No. #2: Licensing freedom vs. licensing restrictions Along with access comes the difference between the licenses. I’m sure that every IT professional could go on and on about licensing of PC software. But let’s just look at the key aspect of the licenses (without getting into legalese). With a Linux GPL-licensed operating system, you are free to modify that software and use and even...

...MICROSOFT ACQUIRES LINUX Introduction The Microsoft Corporation is the largest diversified computer software company in the world. Linux is simply a computer operating system. The stable and flexible nature of Linux has attracted people to use it at home and work computers. Linux has many advantages like they are more stable, secure as well as robust. It is considered to be perfect storage of huge information database. As a competitive strategy, a marketer of a successful product may bundle a newer or less successful product with its stronger product as a means of edging its way into a new market. Perhaps the most famous example of this is Microsoft Corporation's bundling of various software applications. The comparative advantage of innovation and new technologies in the business activities made Microsoft become monopoly. If Microsoft acquires Linux, Microsoft will become still powerful. It would usually cause market failure. Moreover, considering the problem of market failure, Government intervention is inevitable in the case of Microsoft. Government filed a case as Microsoft acted as monopoly. Monopoly If a firm only one which can produces a certain goods, it has monopoly in that market for that good. There are so many buyers in the market and there is a restriction to new firm enters into the market. The monopoly firm produces and sells their output where MR=MC and get abnormal profits before the government regulate to them. The U.S vs. Microsoft case of 1998...

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.

...Windows vs. Linux Enterprise Distribution Recommendation Introduction to UNIX Linux vs. Windows Enterprise Distribution Recommendation X Industries is a large sized business that is in the midst of a decision regarding wither or not to switch their existing Windows-based IT system over to a less proprietary product, Linux. This is no easy choice to make, considering X Industries is currently running 170+ Windows-based servers of various types. Their staff fulfills company operations on these servers with their 750+ array of desktop and laptop computers – all running Windows XP Professional. Linux may just be a little dog in the Microsoft park, but a company that makes the big switch can expect Linux to yield benefits in cost savings, increased security, and arguably better usability. However, each individual enterprise situation is always different, so a cookie cutter solution of which system to use will never suffice. Rather, the numbers through subjects of cost, market share, programming capabilities, software compatibility and availability, and the ever-important user interface will tell the best choice. Cost The only way to evaluate cost is to get down to the basics, and look at the statistics. The first topic of cost will center solely on the price for Windows operating system software, first for the network side, then the node side. Other topics will focus on the cost of the Ubuntu Linux distribution, which will run on the servers and desktops,...

...Electrical & Computer Sciences IJECS-IJENS Vol:12 No:04 25 Studying Main Differences Between Linux & Windows Operating Systems Lecturer/ Hadeel Tariq Al-Rayes Abstract—Comparisons between the Microsoft Windows and Linux computer operating systems are a long-running discussion topic within the personal computer industry. Throughout the entire period of the Windows 9x systems through the introduction of Windows 7, Windows has retained an extremely large retail sales majority among operating systems for personal desktop use, while Linux has sustained its status as the most prominent Free Software and Open Source operating system. After their initial clash, both operating systems moved beyond the user base of the personal computer market and share a rivalry on a variety of other devices, with offerings for the server and embedded systems markets, and mobile internet access. Linux and Microsoft Windows differ in philosophy, cost, versatility and stability, with each seeking to improve in their perceived weaker areas. Comparisons of the two operating systems tend to reflect their origins, historic user bases and distribution models. Index Term— Kernel, Linux, Operating Systems, Windows II. THE ESSENTIAL DIFFERENCES BETWEEN LINUX & WINDOWS (BEGINNERS LEVEL) 1- Drives don’t have letters, they have mountpoints The first thing that usually trips up people who come from Windows to Linux is that filesystems aren’t assigned letters the way they are in Windows. Instead, there is...

...COMPARISON: WINDOWS VS. LINUX This report is a critical comparison of the computer operating systems (OS), Windows and Linux. It is written for an average audience that uses a computer almost everyday and is now curious to know which operating system is better. The audience is assumed to have sufficient knowledge to understand the various aspects of an OS, but is not aware of the specific details of each OS. This report analyzes the different features of both operating systems in order to arrive at a conclusion on which OS is better for daily use. Both systems are evaluated on a wide range of criteria such as cost, installation process, software applications, hardware, user interface, security/stability, troubleshooting, and the implementation of the OS itself. These will help decide which of the two systems is better to use on a daily basis. Before I begin the comparison the reader needs to know that Windows is created, maintained, and updated by Microsoft. No one from outside can access the underlying code. However, Linux is created and updated by volunteers all over the world, which is why there are so many different variations of Linux like Red Hat, SuSE, MandrakeSoft and a few more. The important features of the operating systems are discussed below. COST The Windows operating system is significantly more expensive than the Linux operating system. In fact, the Linux OS can even...

...Elsevier B.V. Linux vs. Windows: A Comparison of Application and Platform Innovation Incentives for Open Source and Proprietary Software Platforms Nicholas Economides and Evangelos Katsamakas ABSTRACT The chapter analyzes and compares the investment incentives of platform and application developers for Linux and Windows. We find that the level of investment in applications is larger when the operating system is open source rather than proprietary. The comparison of the levels of investment in the operating systems depends, among others, on reputation effects and the number of developers. The chapter also develops a short case study comparing Windows and Linux and identifies new directions for open source software research. Keywords: Open Source Software, operating systems, technology platforms, Linux, innovation incentives. JEL Classification: L 10, L86, L3 1. 10.1 INTRODUCTION Open source software is an emerging type of software that may fundamentally affect the business and economic features of the software industry. Linux, an open source operating system, has been the prominent example of the potential of the open source movement, competing against Microsoft Windows, the incumbent operating system. 208 Nicholas Economides and Evangelos Katsamkas This chapter analyzes the incentives to invest in application software and an operating system under two different software ecosystems: one based on an open source operating system, such as Linux, and the other based...

...| Linux and Windows Device Support | 6-3 Short Paper Submission | | By Lauren K Homa | 7/10/2013 | | It is true that the internet hosts an abundance of support websites, forums, links and other discussions regarding Linux and Windows device support. It would seem that this topic has been highly debated for some time as to whose support is best. In my own research, I have found that responses and web sources tend to be biased towards one OS or another based on personal experiences and preferences depending on the task that the system is being used for. I have found one non-subjective difference between Windows and Linux that could help get to the bottom of the discussion: When it comes to Windows, “Microsoft writes generic drivers to help ensure users can get up and running, then 3rd party supplied drivers can be installed to optimize performance. With Linux, drivers are all included with the Linux kernel, and devices are detected and the appropriate drivers are then activated on the fly. There are no 3rd parties to contact for drivers (unless a proprietary driver is needed, in which it has to be manually installed, similar to Windows.” (Clay, 2013) This offers some benefits and costs to each system. With Windows being more prevalent, it’s evident that Microsoft makes an effort to ensure that software is compatible and available with all their hardware drives and devices, and that resources can be readily available to customers if needed. With Microsoft...

...Closed Source Vs Open Source Pao Yang POS/335 03/06/2013 Mr. STERNIERI Closed Source Vs Open Source In the world of operating system we have two options to choose from these is Unix/Linux which is an open source, meaning that its source code made available and licensed with an open source license in which the copyright holder provides the rights to study change and distribute the software to anyone and for any purpose. The other option is the closed source such as Microsoft’s Window which is software released or distributed without the corresponding source code. Generally, it means only the binaries of a computer program are distributed and the license provides no access to the program's source code. The source code of such programs might be regarded as a trade secret of the company. Access to source code by third parties commonly requires the party to sign a non-disclosure agreement. I also will like to discuss what source codes are and why having the right combination will give us free bees. What some of the major differences between an open source and a closed source? I see it all over the internet the heated debate of which is better open source or closed source and even though both sides have good supporting evidence to back up their claim about every from which is more secured to who has the better functional software. The argument of Windows vs. Linux is a greatly debated one, and in recent years has become quite heated. Because Microsoft's attempt to recover...

...Linux vs Windows has been a subject of debate since the inception of computers. As told by Severance, (2008) LINUX was originally developed at Bell Laboratories as a private research project by a small group of people starting in 1969. Linus Torvalds, who was then a student at the University of Helsinki in Finland, developed Linux in 1991. It was released for free on the Internet and generated the largest software-development phenomena of all time (Linux's History, 2000). Today LINUX owns about 10% of the market share and this has dropped in recent years as both Windows and Linux have increased their share of the available market with Linux currently holding about 20% (Galli, 2007). As noted by Windows History (2006), many long-time PC users trace the Microsoft Windows operating system to the 1990 release of Windows 3.0, the first widely popular version of Windows and the first version of Windows many PC users ever tried. However, Microsoft initially announced the Windows product seven years earlier and released the first version in 1983. In its early offerings, Windows was still based upon the Disk Operating System (DOS), but it brought a much needed Graphical User Interface (GUI) to the mainstream computer market and began and evolution (or revolution) of the computing industry which resulted in Microsoft owning about 70% of the world-wide market share (Galli, 2007).

But basically WebOS Servers are common operating systems serving the public over the internet. Most of these are server editions vary among todays popular operating systems like Windows, Linux, MAC, and UNIX. An additional platform is usually common to layer on top of these operating systems and these come in various flavors as well depending on the function of the website. This paper will target the popular server operating systems that are common on the internet today with emphasis on why these systems are popular and some of the features these systems offer as systems suitable for internet servers. Windows Servers Without question Microsoft Windows bases servers are among the most popular servers on the internet today. Need proof?

...Comparison of Windows, Mac OS X and Linux Operating Systems Team A POS/355 March 6, 2015 Memory Management System Memory management is the process of allocating memory during your programs runtime. Memory Management in MAC OS is a multi-core and multi-processor execution that is supported and a programming API, which is called grand central dispatch. It is in the MAC OS. It provides a pool of available threads. There are ways to prevent memory related problems; Freeing data that is still in use, this can cause memory corruption that can result in your application crashing or worse corrupted user data. The MAC operating system can provide most concurrency as possible based on the number of cores available, and those threads depend on the capacity of the system. Windows memory management system is both physical and has virtual memory. It is mainly controlled by the virtual memory managers and pages. “Windows operating system operates on many platforms then it uses page sizes that can range between 4KB to 64KB. So this means that windows virtual memory can control how memory can allocate paging performance” (Stallings, 2013). Committed, Available, and Reserved are three types of regions of space or memory that the operating system can manage. Committed region is space it’s pages that have been stored either in physical or virtual memory. It also allows the process to access the virtual memory pages. Available region is where the address of the process is not being used...
