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. Developping the early OS began in early 1950’s where the initial code is written in assembly language but soon after the evolution of C language most of the design for early unix is done in C language and the evolution lead to the opensource linux kernel which may or may not have used the complete unix kernel But linux is the one of the successful opensource operating systems that is still current. It has a lot of versions and ditributions.

The developing of the os is a large typical process where 1000’s of line of code is written inorder to acces the hardware resources, the typical and main constarints are to effectively use the process, memory and io management of the system. The process management initially dsesigned for sigle operations and then switly evaluated for running multiple operations which are actally not run simpultaneouly but run concurrenty usung the effective cpu clocks. The effective management of file and storage, security, deadlocks, user interfaces both gui and cli all these are pretty much challenges and one of the main portions of thedesign. The initial los version built with 100’s of lines of code to the newser ones that comes with the millions of code written and compiled. Linux as told earlier is one of the succsesfil operating systems that is under the open source license. The kernel of linux is freely available and the initial computer revolution made the new developpers and the big companies to use the kernel and comeup with their verion and distributions whre a they packed the os and sesigned it so as to target the particular group. As linux can use very less resources of a computer being the codes is very low level written and can interact more freely with hardware it can be ported to the system with Kb’s of memory and also can be embedded in the small systems calld embedded systems.Linux also called the GNU-general public licence is released under GNU-opensorce license with their second version of kernel ,Within an year the windows-X si ported to linux which is the basic underlying GUI for the Unix/Linux like operating systems.Ever sisnce the release of the kernel 0.01 a large no of programmers have contributed to the evolution of the different version by writing and improving effective tasks like coming with a new memory management structure, successfully redusing no of deadlocks and everytime these deveopments are ported and released with the newer versions of code than is again used by the programmers . This process of the new kernel versions in the middle undergone a susbstainary changes with th new GNU licence and the new kernel release modifications and to this date the new kernel version stays at 3.0.1 Linux is a monotholic kernel the device drivers and modules will for the most part directly talk to the hardware and unlike windows the graphics systems in the linux doesn’t run in the kernel.Being linux can be effectifely use the hardware resources and is freely available its extensive adoptability came from scientific and educationsl instititions where it had a new life as these are everytime updated for the application specific usages. Till date Linux flavours are mostly had their percentage share in server operating systems.

Gnome< Kde can be considered as one the successful desktops fo the linux distros. With these the linux has been given a competitive advantage in desktop based market where a large no of ope source packages are distributed with the linux, Networking bening a prominent feature for the operating systems is also well ported and one of the early apaches servers are first ported ina next System which in turn desined with the linux like kernel as its subsystem. Better security that built around the linux is one of the prominent features for large organizations to use linux servrs for their needs.Teh major contribution that came from is the LAMP which is Linux –os,Apache server,MysQl(or mango DB), PHP/Perl language. This distribution pack is often bundled with the opensource linux like Ubuntu suse and also like proproitery like redhat.Linux also is been with the supercomputers almost 80% of the supercomputers are build around linux operating systems , Linux also around portable devices , Most succesfful os like Android is built arount it, Web os, Chrome os are also prominent os that build around linux.The way that linux is designed it is well suites for clustered systems suppose an oracle server witth a 3 node cluster a computwr with linux can server in better management of oracle database than any other operating system with the same level of resources available.

The major drawback still now is that linux lacks support for the end user support, and so though linux is vastly used in servrs around the world a large portion of it is dominated by the Red-hat operation systems which is not a open sosurce operation system but built around the same kernel distributions and has vast support within the red-hat community.

Open and Closed Source Operating System Comparison

...Open and Closed Source Operating System Comparison POS-355 Open and Closed Source Operating System Comparison Open and Closed Source are the two model of how most software is distributed. The open source code is that exactly, free open-sourced code. Meaning the core functions of the written code are given to a potential developer and that developer is able to manipulate, add to, or change any of the functions of the code. This holds true from the basic core functions or the code to small additional code snippets. FOSS or free and open source software do not typically limit or inhibit the use of the software. However with all of this free distribution, there can be some open sourced software that might have license-based restrictions or redistribution. These restrictions are not overwhelming though. The software can be re-distributed for free, after a developer has modified the code, as long as credit is given to the original manufacturer. FOSS also allows for the code to be modified and then re-compiled, so it can be sold as a complete project. Some examples of this type of re-distribution is Red Hat Inc. Red Hat Inc. takes different pieces of code, pieces it together into a really nice and user friendly interface, and then Red Hat re-distributes this re-compiled code as Red Hat Linux. There have many different flavors and iterations, but as long as Red Hat gives credit in the development to the originally creator, there is no problem with Red Hat re-distributing this...

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.

...also known as software libre, or open source software, is a type of software that can be used and modified by the software owner, as well as redistributed. b. Free software is not synonymous with "freeware," which is software that is available for use free of charge, but may or may not be modified. This software is sometimes also free of charge, but sometimes requires a fee to purchase; the "free" in the name refers to the fact that it may be freely used and changed. 2. Why is Linux popular? Why is it popular in academia? a. It is very fast, easy to use and reliable. Writing programs and scripting on Linux is often times much easier than doing so on Windows as many of the users are that use Linux are computer savy but also because the framework that makes up Linux is completely open source, thus allowing programmers to program with Linux not around it. b. Students understand the source code for the operating system and how Linux works without complications. 3. What are multiuser systems? Why are they successful? a. A multi-user operating system is a computer operating system (OS) that allows multiple users on different computers or terminals to access a single system with one OS on it. b. Because you can add a user to your computer and have a different profile then another user, instead of buying another computer. This makes it cost effective. 4.

Social Issues

...Abstract  Linux and Microsoft operating systems have been developed and marketed in two very different ways. Microsoft has become synonymous with monopoly and substandard software, while Linux is based on free, open source and the concept of open standards, full disclosure and sharing. Microsoft attempts to discourage consumers from using the Linux solution by suggesting that the operating system is less than perfect, yet it remains blind to its own operating system's problems existent within Windows 95/98 and Windows NT.  It's a well-known fact that Microsoft dominate the software market despite these facts. Are they operating within legal and ethical boundaries? And is it possible that they could fall from grace because of this?  `When you say "I wrote a program that crashed Windows", people just stare at you blankly and say "Hey, I got those with the system, *for free*".'  (Linus Torvalds)  Introduction  Linux and Microsoft operating systems have been marketed very differently. The objectives of the two factions are very different indeed. One seems to be oriented towards market domination, market cornering and making the most amount of money it can, and the other towards creating a free, open source operating system. This may sound too simplistic with the two extremities, and may be a bit more complicated. This report will investigate into the differences in the way that the Linux and Microsoft operating systems have been developed and marketed, and how Microsoft...

Gnu-Gpl

...Open Closed Source Systems - GNU-GPL Paul Ray POS/355 March 23, 2014 Ptof. Singh, MBA, PMP, CCIE Open Closed Source Systems - GNU-GPL The Linux kernel is distributed under the GNU general public license (GPL), the terms of which are set out by the Free Software Foundation. (Stallings, 2011) Linux is not public-domain software. Public domain implies that the authors have waived copyrights in the software, but copyright rights in Linux code are still held by the code's various authors. Linux is free software, however, in the sense that people can copy it, modify it, use it in any manner they want, and give away their own copies, without any restrictions. "Without a community of developers their probably would not be any free software.” (Wolf, Miller, & Grodzinsky, 2009, para. 1). Wolf (2009) GNU is a Unix-like operating system that is free software that respects your freedom. You can install versions of GNU (more precisely, GNU/Linux systems) which are entirely free software. GNU stands for GNU is a recursive acronym for "GNU's Not UNIX!" Wolf (2009) Free Software (FS) is a notion that was first introduced by Richard Stallman in 1984 at the beginning of the GNU project. The Free Software Foundation (FSF), founded in 1985, supports the ethic of Free Software, which is embodied in the GNU General Public License (GPL). The FSF defines free software as a software licensed so that it supports four freedoms. The first and fourth freedoms are pertinent to...

It302 Research Assignment 4.1

...Free and Open Source Software (FOSS), by 2006, had allegedly violated 235 patents that Microsoft was in possession of, including the Linux Kernal, Samba, OpenOffice.org, and others. Three contracts were struck up between Novell and Microsoft, most notably, a patent agreement that stated, “Don’t sue us and we won’t sue you.” When this happened, some dire consequences were predicted for FOSS, however, it hasn’t exactly gone as predicted. FOSS has blossomed since then. It is my opinion, that in entering these contracts, Microsoft put more of a light on Open Source, which then attracted the attention of other programmers, and in general, people who like free things. There is a very strong market for Linux going right now with GUI enabled operating systems including Red Hat/Fedora, and Ubuntu. They are having great success and continue getting updates, and users, on a growing basis as people experience, and learn how to use the command line. It doesn’t seem like much impact has been made, other than most companies have started using Open Source as a way to make their product better and more efficient. A few years back both MySpace and Facebook open sourced Qizmt and Tornado, respectively, not to garner any love from the people, but to try and make them better, and more efficient (Asay Sept. 16, 2009). More than anything, I would say Microsoft is feeling the hurt, they are losing money with so many people looking toward the Free and Open Source Software markets. Who would want...

Important Features of Linux

...Important Features of Linux 1. Many free iterations. Many of them to choose from with all of their own benefits 2. Highly customizable. Many of these Linux distributions can be set up like other existing operating systems to set your own level of comfort if you should so desire 3. Many free applications. Many different applications to choose from that are open source so that means free applications that work like other existing applications so you can not have to worry about having a program that isn’t compatible with Linux. 4. Secure. The Ubuntu desktop version specifically has a built in firewall that will protect your files and comes with virus protection as well. There isn’t many viruses out there for Linux to start with compared to the other operating systems. 5. Scalability. Linux can run on a wider range of hardware and is very fast in the way it works with your current hardware. If it doesn’t already work with I/O devices, there is easily a way to download signed or unsigned drivers to get it to work most of the time. You could even use your old computer as a file server or backup server by installing Linux to run it that way. 6. I/O Compatibility. Linux also works with a range of devices from mp3 players to printers and the drivers are easily installed automatically not to mention compatible with certain Microsoft software products as well, all for free! 7. Open Source. As I have stated before all of the source code is freely available to......

...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.

Open Close Source

...Closed and Open Source There are a lot of things that go into a practical and an efficient operating system; one of which consist of a closed and an open source. To understand the sources of an operating system, it is best to find out and figure out what closed and open source is. Closed and Open source can be a disadvantage or an advantage of software development and cost sharing. The initial step is to recognize what it means to have a closed or open system, and what components are needed and will make up the requirement for software or an application to function. With both closed and open sources functioning differently as to how the system is programmed and structured and how the system will function within a software application or program. OPEN SOURCE Operating systems of an open source can be defined as free software developed by corporations or individuals to develop an alternate to not having to rely on any individual or one company to modify or change the software and maximize its used for the individuals or companies' advantages. Open source are typically free to use by each individual or companies to modify and changed without having to worry about the licensing and compliance to the original developer of the software being used. These are the advantages to an open source system. * Unlimited Community Support: With the public support, the alteration and transformation of the system is more frequently, more elaborating on time to develop a......

Linux Operating Systems

...Linux Operating System Mark Stansbery POS/355 Alicia Pearlman May 5, 2012 Linux is an operating system just like Windows, and MAC OS, but more along the same lines of the UNIX operating system, because they have some of the same features. Out of the three most popular operating systems, Linux is surprisingly enough is the least popular. It is growing in popularity as more and more systems start to use it, but it still has a long way to go. The information that follows will give some of the history behind Linux and the features, benefits, and drawbacks to the system. In 1986, Linus Torvalds began to learn, quite extensively, hardware programming to help him with his Sinclair computer. He developed a floppy controller driver as well as a programming tool to help him with his efforts to better understand and improve the performance of his machine. In 1991, Torvalds got his first 386-Intel based PC, which ran a version of UNIX called Minix. Minix was developed as a learning system and was very popular in the universities. Torvalds found out very quickly that he did not like the Terminal emulator that was provided, and since the source code for Minix was open source, he began a project to develop his own code to design an improved emulator that provided more functions especially on a hardware level. As he further developed the code and more functionality was added Torvalds decided that his design was more on the lines of an operating system instead of just a......

Foss

...FOSS Free Open Source Software This means you have the freedom to copy and re-use software rather than to have to pay for each version or new edition. Though the term is used inclusively there are differing ideas surrounding each. For example Free software is more about the freedom it gives user whereas Open Source is praised for the strength of the whole peer-to-peer modle that is used. The whole general idea of FOSS arose in the 1980’s through one Richard Stallman who was the founder and creator of the GNU project which later went on to become the Free Software Foundation. FOSS philosophy simply states that it is the right of every user to use, modify, and distribute computer software for any purpose. The right to use, distribute, modify and redistribute derivative versions, the so called "four freedoms," are based in and representative of an extreme form of anti-discrimination resistant to categorization into the typical “left, center and right” political schema. This element of nondiscrimination, coupled with the broad nature of FOSS's philosophical foundation, enables the easy adoption of FOSS technologies. FOSS's broadly defined freedom acts as an important starting point and one conceptual hinge useful in understanding the wide circulation of FOSS as a set of technologies, signs, methodologies and philosophies. An analysis of the way in which this philosophical and legal form is animated and redirected in particular ways through the use of FOSS......

The Future of Media

...Introduction To Open Source – Open source media means media software with no restrictions There are open source forms of media and closed source forms of media. Open source has been growing more and more rapidly in the past decade as most forms of media we have discussed in class on Friday mornings. With an open source form of media software, programmers share their codes freely in order to be modified and used by others. They are allowed to alter and change software with improved features. For open source programs to be reliable, licensing has to be approved by Open Source Initiative, which is a corporation that certifies shares and promotes open source software. Where Open Source Came From Open Source began with the Hacker’s society of the United States computer science lab in Stanford MIT in the late 1960’s. It was a collective were members shared their code with other members. This would allow members to use each other’s knowledge to improve their own interest. In the 1980’s the Hackers Society began to fall apart after the members were hired by commercial companies to produce systems that required users to purchase a license in order to use them. Later they left those commercial companies and recreated the hackers’ society. One of the first open source systems was a Unix compatible operating system named GNU by Richard Stallman. What The Open Source Is Open source is similar to “free software”, but the open-source users are generally......
