...NT1430 Linux Networking Research Paper Nicholas Lorick ITT Technical Institute St. Petersburg Campus NT1430 Linux Networking Research Paper All people in the IT field are familiar with the IPv4 protocol and they are quickly becoming familiar with the IPv6 protocol. Bradley (2012) states the following: Since the beginning of the internet, IPv4 has been synonymous with IP and few people ever stopped to think about which version of the protocol it was. But IPv4 has outlived its usefulness. Its successor, IPv6, after nearly two decades of development is finally ready to replace IPv4 as the backbone of the Internet. (p. 34) With all the new technology and devices now accessing the internet the move to IPv6 will eventually happen. According to Bradley (2012), IPv4 is out of IP addresses. IPv4 supports only 4.3 billion addresses; and with PCs, smartphones, tablets, and gaming systems connecting to the Internet, we are running out of IP address. IPv6 uses 128-bit addresses and can maintain 340 undecillion (340 × 1036) addresses. The IPv6 protocol brings with it other benefits. With IPv4 most of the internet relies on Network Address Translation. With IPv6, every device can have its own unique public IP address. Most home and small-business users have one IP address on the Internet -- the one for the router that links their hardware to their ISP. The router issues IP addresses internally to the devices that attach to it, but it must constantly keep track of which traffic...

...WHITE PAPER MICROSOFT WINDOWS SERVER VS. RED HAT ENTERPRISE 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.

...Week 4 Individual Paper: Operating Systems Analysis Paper POS/355 November 7, 2011 Jeff Rugg Introduction The operating system, commonly known as OS, is the brain or the center of all computer systems. It controls the input/output and controls various tasks of the hardware. Apart from serving as a go-between for application programs and the hardware of the computer, the OS also consists of information and programs while providing general services to make sure that several software applications can operate accordingly. Operating systems can be found in almost any type of a computer device such as personal computers, supercomputers, cellular telephones, and video game consoles as stated by Linux Systems (2011). As the research was being conducted for this paper, it raised a question whether the internet uses the operating system? It proved to be a challenge to actually pin point the most common operating systems on the Internet, but as the research continued, it was obvious that these three, Windows, Mac OS X, and Linux are considered to be the most common operating systems used on the Internet today. Background of each Operating System Windows Privately owned operating systems, Microsoft Windows is generally used on personal computers and as of today, the most commonly used version is Windows XP with the new version of Windows 7 for personal computers and Windows Server 2008 R2 for servers is entering the market. Mac OS X Mac OS X is a graphical operating...

...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...

...UNIX, Linux, and Windows Server Critique Abstract The following sections in this paper focus on analyzing operating systems for Riordan Manufacturing Inc. that specializes in plastic molding and design. Team B concentrated on five main areas of UNIX, Linux, and Windows Server. The five areas include Security, Administration, Networking, Performance, and Programmability. The team explains the existing systems, followed by comparing advantages and disadvantages of each operating system. The comparisons provide insight for Riordan’s IT specialist and administration considering which system to implement. Interesting topics that relate to security weaknesses, and advantages that UNIX® and Linux® compare against the operating giant, Microsoft Windows Server®. Security At the present time, Riordan Manufacturing’s network configurations consist of a heterogeneous UNIX and Windows environment. UNIX has been around for more than 40 years and is known for its’ robust power and scalability. According to the Open Group, “Security, which is often seen as a weakness for UNIX-based systems, is ensured using dedicated communication lines and secure communications protocols, along with strict authentication procedures” (para. 42). This means UNIX, just like Windows, requires configurations to make it a more secure system. Setting up file permissions, user access controls, as well as shutting down network services not currently active are just a few of the ways that help close the gap...

...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...

...Term Paper System Analysis and Development Professor Blaine Easterwood Chris Donacki September 6th 2015 When beginning to build a web architecture there are several things that need to be kept in mind. Firstly, performance, this is one of the more important considerations, the speed of a website has a direct impact on both the effectiveness of the website and how satisfied the users will be with the website. Not only that, it does play a role in search engine ranking which directly correlates to possible revenue if applicable. Due to this creating an optimized site with low latency is very important. Reliability, any system, every system needs to be if nothing else reliable. I mean this in a sense that data will remain consistent. Scalability, when it comes to any system size is just another aspect that needs to always be considered. Given how fast some businesses can grow on today’s internet this aspect is especially important. Any future growth must be able to be accommodated. Manageability, having a system that can easily diagnose and manage any problems additionally effects any possible revenue, essentially the only time you won’t be able to make money off of a website is when it’s down. Having a system that is highly manageable has an effect on everything else. Finally, cost, this should more or less go without explaining. How much it will cost to build the architecture from the ground up, and how much one would have to make in return for it to be a profitable venture...

... Any topic (writer's choice) Name Institution Paper instructions: Describe some reasons why Linux is installed on only a very small fraction of desktop computers. Linux is a robust multi-tasking networked open source operating system that has attracted a large market in recent past. The operating system is becoming popular with mobile phones and enterprise software and can only be installed on a small fraction of desktop computers for the following reasons; The installation process can get complex at times to a normal user. This may require support which may increase the total cost of ownership despite the software being free. Also the number of users using Linux desktop deployment is small which keeps firms off from porting desktop applications to a Linux environment. In addition, only a small amount of money is saved when someone decides to invest in Windows operating system. Are there particular categories of products or users who might see Linux as more appealing than conventional operating systems? Do you think Linux's share of the desktop market will increase? Why or why not? Linux offers robust security measures making it hard to be hacked. Firms running sensitive data and information could improve the security of their systems by using Linux as opposed to MS-Windows which is vulnerable to hacking (Gallaugher, 2013). Similarly the operating system...

...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...

...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.

...Linux is an open source operating system. Considering the difficulties and risks in developing an operating system, is it surprising that Linux has been as successful as it has? What makes it so successful, despite these difficulties? Write a short paper answering this question. OpenSorce Operating systems:- Opensource operating systems are the operating systems that are designed and licenced in such a way that they are free to use, free to change the os and can be distributed for free.the source code used to design the os is made free to public so that people can change and modify depending on their needs and can create their own custom versions and re entitiled to be mostly free the examples of the open source are linux operating systems like Ubuntu,Free BSD.The contrary of the opensource os are the regular copyrighted os and software where source code is not entitiled to be realsed and the os is completely copyrighted with the publisher like the windows and macos. Developping an Operating systems. An operating system is a software that will interact with the hardware resources of the computer and effectively use them inorder to input from the user/interface and get the desired results.

...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...
