...1-3 Short Paper: Open Source Operating Systems Southern New Hampshire University September 7, 2014 In 1991, Linus Torvalds created Linux and after a couple releases and improvements, the computer community caught on. Some advantages of the Linux Operating System are low cost, stability, performance, network friendliness, flexibility, compatibility, choice, fast and easy installation, full use of hard disk, multitasking, security and open source (Haas, 2014) . There is no major initial investment needed to obtain the Linux operating system. There is no fee for a license unlike Microsoft Windows. For comparative purposes, Windows 8.1 64-bit is retailing for 96.99 at BestBuy and 99.99 at Newegg.com. With no initial monetary investment, Linux gives many potential users an opportunity to try the OS. The ease of exposure to the Linux OS make it easier to increase adopters and faithful users of the OS. Linux’s stability can contributed to its user permission design. Linux runs with lowest permission levels possible which minimizes the possibility of damaging the system. Linux is written to survive in the way it keeps program memory space and system kernel resources separate (Cedar Valley Tech, 2009). Also since Linux is open-source, bugs are fixed by an army of ready developers who are not trapped within the confines of a software manufacturer. Though no operating system is perfect, Linux can run for years without needing to be restarted (Godbey, 2006). Linux performs well due...

...Linux has grown in popularity and capability over the years, but is it competitive with its competition. In this paper an overview of the Linux 2.6 Operating System (OS) and how it functions/performs on the technical level will be discussed. Comparisons to other retail OSs such as, Windows, Mac OS X, and prior versions of Linux will be used to show the strengths and weaknesses of this OS. “Linux was created by a student (Linus Torvalds) in Helsinki in 1991 with the assistance of developers from around the world. Linux is free, it shares its work with everyone — including competitors — and its business model is motivated primarily by adrenaline, altruism, and peer respect rather than by money. Yet, Linux's functionality, adaptability and robustness has made it the main alternative for proprietary operating systems, especially where budgets are a main concern.” (OEDB, 2007). As it is stated above Torvalds creation was a key proponent in creating the Open Source Movement, which has paved the way for the many distributions of the Linux Kernel. In the beginning Linus Torvalds was an IT student with the desire to test the limits of his current computer. During this time Torvalds was working with the MINIX OS which was create to be a cheap alternative to UNIX. Torvalds wanted to modify the kernel of MINIX and found that this was not possible so he began to create Linux. In the beginning Linux did not offer a lot of features and seemed to be lacking in ability (Diedrich, 2011)...

In other words, the operating system is what allows the software to talk to the hardware, such as storing information to the hard drive, to send out print jobs to the printer and so on and so forth.

Linux, like Microsoft Windows is an Operating System. Unlike Windows, however, Linux is open source, meaning one can readily find the source code for the OS for free and add or edit the code to his heart’s content. 1Library A library is a collection of implementations of behavior, written in terms of a language that has a well-defined interface by which the behavior is invoked. This means that as long as a higher level program uses a library to make system calls, it does not need to be re-written to implement those system calls over and over again. In addition, the...

...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...

...Android: Is Open Source Better for the Masses? Jarrod R. Worlitz ITT Technical Institute, Sylmar Campus EN1420 Abstract This paper makes the argument that Google’s Android Operating System and the open source platform it provides is superior to its major competitor, Apple’s closed source iOS. The focus will be on how the ecosystem of “smartphones” and other mobile devices (such as tablets and phablets) has been impacted by Google, Inc.’s decision to release the Android Operating System as “Open Source Software” (OSS), allowing for a wider adoption of the platform than was achievable by Apple Inc.’s iPhone, whose marketing strategy and decision to is control both hardware and software. The claim will be supported by explaining the superiority of Android in terms of its benefits to manufacturers, consumers, and software developers. Android: Is Open Source is Better for the Masses? One of the fastest growing technologies is mobile computing. This fascinating trend in communication was propelled in large by the introduction of smartphones. Smartphones provide instant access to information and programs only previously available users from a desktop PC. To be clear, there are many other such mobile devices on the market that do not qualify as phones, such as tablets and “phablets” (a hybrid phone and tablet) however their roots can be traced back to two major platforms. These platforms are maintained by some of the largest companies in a competitive market. The two...

And although the concept is still applied in current IBM systems, the popular concept of a VM has broadened and been applied to a number of areas outside of virtualization. Virtual machine origins The first operating system to support full virtualization for VMs was the Conversational Monitor System (CMS). CMS supported both full virtualization and paravirtualization. In the early 1970s, IBM introduced the VM family of systems, which ran multiple single-user operating systems on top of their VM Control Program—an early type-1 hypervisor. The area of virtualization that IBM popularized in the 1960s is known asplatform (or system) virtualization. In this form of virtualization, the underlying hardware platform is virtualized to share it with a number of different operating systems and users. Another application of the VM is to provide the property of machine independence. This form, called application (or process) virtualization, creates an abstracted environment (for an application), making...

...International Journal of 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...
