...Systems: Open or Closed Source Donald C. Dodd POS 355 06/09/2014 Dr. Bruce Huang Operating Systems: Open or Closed Source One of the biggest questions when choosing an operating system is whether it is free or not. Let’s face it cost face it cost is always going to be part of a deciding factor when it comes to making a decision in business. And free always sounds good but usual comes with some type of string attached. In this paper I will discuss what are open and closed source operating systems (better known as OS) and how they differ. As well I will discuss some of what you can expect and what not to expect from open and closed operating systems. And lastly I will give examples of each a closed and open OS. OS is often confused with things like word and excel but those are really applications that run within an OS. These applications are members of the Microsoft Office suite that is compatible with the Windows OS. The windows OS is an example of a closed operating system. What is a closed OS? A closed OS is an OS that the source code is kept private. Closed OS’s are typically made by one company and only the final product is made public. (You will see beta versions but typically these are close to final products). With closed OS’s you need to by licensing to make it work, without a valid license the OS may become inoperable thus rendering your computer useless when the companies “trail” period ends (usual within 30 days of installation). After purchasing closed software...

...Comparison of open source OS and closed source OS Ted Wallick University of Phoenix The definition of closed source Operating System(OS), is any OS made but it's code and functionality is private to the vendor that made it. The end user can neither look at it's core/kernel or change it in any way. If an end user needs a change made, a change request has to be sent to the vendor to get adjustments made. This is how most commercial software is developed. Microsoft Windows OS (PC and mobile), Apple OS X, IOS, and UNIX, are primary examples of closed OS. Closed OS has some Pros and Cons. Pros: * Vendors have complete control over hardware and functionality. * The vendor gets to set some standards with how software and hardware are developed to work with the OS. * Vendor controls Versions and updates * Vendor controls any security issues (personally I would not want this hot potato) * Vendor has some control over what 3rd party developers make * Easier for the OS vendor and 3rd party developers to make money. Cons: * Response to system exploits (things that allow hackers to do whatever) is slower than open source OS due to a limited amount of code monkeys that have intimate knowledge and access to the OS code base * Closed OSs cost end users money hand over fist. Major upgrades will cost money. Most 3rd party software will cost large amounts of money. This is only fair to the people that put great time, effort and money to develop the tools...

...Open source and closed source operating systems Dennys Bayona Yevgeniy Tovshteyn University Of Phoenix Computer and Operating System Components Date: 5-May-15 Closed-source operating systems are systems that are owned by an organisation and sold for a profit to its customers. The OS systems uses codes that are proprietary and kept secret to prevent its use by other identities. While open-source operating systems employs the use of code that is freely distributed to every other user thus available for everyone to use, besides can be used for commercial purposes without any problem. The two type of operating systems can be differentiated in respect to the following factors. 1. Bug Free and Source Availability Closed Source Operating Systems don't reveal their source code; as a result the only people who can debug the source code are some of those who work in the company. The budget for the debugging is always limited. If there is a vulnerability in the code, it must be discovered by the company itself (Anderson, 2002); because there are a limited number of developers assigned to the project, it is possible that the vulnerability will go unnoticed. Open Source systems, as the name indicate, make all their source code available to the public. Everyone who knows enough programming skills, and is willing to read the source code, can debug it. In fact, this makes the debuggers numerous and worldwide. They read the source and debug it for their own reasons: maybe to help...

...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...

...Option One GNU Introduction The GNU or General Public License plays a major role today in the way people think of programs. Richard Stallman of the Free Software Foundation (FSF) was who originally written the GNU or simply GPL. The case is, most software’s don’t want you to share or change the program. This means that they are trying to take away freedoms of having the program. What the GNU General Public License is designed to do is the opposite of that because it offers freedom to share and change the software and to make sure it is free for all of its users. This creation caused it to be the most widely used free software license. The GPL accounted for nearly 65% of the 43,442 free software projects listed on Freshmeat as of August 2007. Some believe that the copyleft provided from the GPL was crucial to Linux’s Success because it gave assurance that the work done by programmers who were involved in the kernel would remain free and benefit the world. After the first version of the GPL, more were made that followed. The first GPL was made in 1989. After that, another version was made with similar licenses but there was concern over problems in the GPLv2 so they made another one in June 2007. Preamble The General Public License was designed so that it meant that the people won’t think of a free software as related to its price but more to freedom. What this means is that people can do almost anything to the program including, making copies, giving away copies, selling...

...Open/Closed Source Heidi Mitchum POS 355 May 6, 2013 Michele Gamberutti Open/Closed Source The background behind an operating system stems into different branches of a tree. There are many items that go into a functional operating system. One of which includes open and closed source. To understand what may be a source for an operating system is the first step to understand what an open or closed source is. Even though at times it can be a wasteful effort, open/closed sources can be an advantage of cost sharing and software development. First it is a good idea to find out what it means to have a open or closed source system, meaning components that make up the functions needed for an application or software. With both open and closed working very differently as to how the system is developed and how they run within a software program or application. Each of these sources will be discussed. Open source systems are typical used for everyone to see and for anyone to use, and this is why the name is open. There are advantages to having an open source system which include: • Larger Development Support – Giving a large support system the developers feel as though they can make changed when and where every needed (Vidal, 2013). • Customizable – Having full control of the system gives developers a sense of control to make changes to the programs for advancement in all areas (Vidal, 2013). • Security – Having two eyes is better than one, having more security...

...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...

...A Comparison of Inter-Organizational Business Models of Mobile App Stores: There is more than Open vs. Closed Roland M. Müller1, Bjorn Kijl2 and Josef K. J. Martens3 1 Berlin School of Economics and Law, Department of Information Systems, roland.mueller@hwr-berlin.deUniversity of Twente, School of Management and Governance, 2 b.kijl@utwente.nl, 3j.k.j.martens@alumnus.utwente.nl Abstract The purpose of this paper is to analyze the competition among mobile app stores for smart mobile media devices. Therefore, the business models of seven mobile app stores are analyzed with a special focus on Apple and Google. We use e3-value modelling - a formal business modelling technique - for analyzing the critical elements of these mobile ecosystems. The analysis of the app store ecosystems allows a differentiated view on the different strategies of the app store owners. Additionally, we look at the impact of network effects, economies of scale, platform differentiation, quality assurance, and transaction costs on the design of mobile application markets. This theoretical model allows a deeper discussion about the design choices and success factors in the different app store cases. Based on our analysis, we expect that the open versus closed models discussion becomes less relevant - so-called open platforms have closed aspects as well as the other way around - and that competitive differentiation and segmentation strategies will become increasingly critical in order to strengthen the...

...Open and Closed Source Systems For this paper, I choose option 2, which is to explain and compare Open and Closed source systems. Software is identified in two forms, source and binary. Source is the form in which users write software. This is where Open and Closed source systems/software come in. While they both deal with the way systems are accessed, and the software, and the rights and restrictions of that software, they are complete opposites when it comes to what each (Open and Closed) does and protects. Open Source systems and software are those in which the software has no real restrictions on what a user may do with the software. The most common names for Open source systems are free software, Public Domain Software, GNU software and copylefted software. When this type of system or software was first brought to the public most commercial software vendors and users ignored it, claiming it was a fad, and would quickly disappear. Unfortunate for them, Open source systems and software have actually become one of the most prevalent forms of software available to the public, and a lot of “techie” companies and users use it, due to the fact that the source code is open, therefore, the software can be changed and used as the user sees fit. Closed source systems and software are the complete opposite of the Open source systems and software. Closed source systems and software that is sold by commercial vendors and users is sold with the source closed, and in binary form, hence...

...Open and Closed Source Systems Students Name POS/355 Date Instructors Name Open and Closed Source Systems Open and closed sources is a term that not many people know the difference. According to Damicon (2003-2009), “True-open-source development requires that a community of software engineers band together to work on the software.” What the company is stating is the more minds are used to develop the software the better it will be. Now a closed source is a little different. “Closed-source programs are owned by someone (or some organization) and distributed through a variety of retail channels including the owner's website Damicon (2003-2009).” Basically a closed source is the complete opposite of an open source. Now that the two are clearly defined to a better understanding users will be able to tell the difference. Open sources are gathering of many users and putting the knowledge and experiences that they have obtained over the years and used to make software. Like the saying goes, “Two heads are better than one (Two heads better than one 2014).” Typically open sources are free of charge and can easily be download. For example most people have at least either downloaded one of these browsers; Goggle Chrome, Firefox, Java, or BitTorrent. There are many more open source systems, but these that were just mention can be installed in MAC OS, Microsoft Windows, and LINUX. The positive about having open source is that it is able to be customized to the users liking and can...

... | |Date: |11/11813 | |Re: |Individual Assignment for Week 3 | Today we need to discuss the difference between open source and closed source operating systems. When it comes down to the difference between the two we are going to look at difference with Android and iPhone. These two offer great insight and benefits with going one route vs. the other. • Android When it comes to open source the first thing that comes to my mind is Android. Android is an operating system that is an open source format and the benefits that it provides to its customer base is larger developer support, customizable, more secure, and extended community support. It has more developer support because anyone can develop for the platform; it is customizable because the developer can only change what the original developer chooses. It has the ability to be more securing because it is more transparent than closed source. This allows more people to look over the code to find any bugs and vulnerabilities are spotted much quicker and can be fixed. The community provides the extended support because the original developer might move on and stop developing the product and now the community can take over and extend the usable life. • iPhone Then when...
