...constantly debated in the industry). Be sure to support your response. An operating system can be thought of as the link between the computer hardware and the software that is used to perform various tasks. Without an operating system the software applications and computer hardware itself cannot function. Each operating system usually consists of several features, among them memory, processor, device and file management but there are also networking features, security and I/O functions to be considered. Due to the similar nature of computer hardware then many operating systems will require most, if not all of those functions. However, from a technical perspective if we examine the interaction between the core computer hardware and the system applications then it is possible to narrow down those functions that can be deemed essential. The core of the operating system, usually known as the kernel, provides the most basic level of control over the hardware. We can assume that the hardware would consist at the very least of a CPU, Memory and various Devices and the kernel would be responsible for managing each of these as required by any user interaction or application request. While this may be a functioning operating system, practically File management would be required and increasingly security and network functions can be considered as mandatory given the modern utilisation of applications and operating...

...Contrast and Comparison of Operating Systems Team B will take what we have learned from our course POS/355 Operating systems and research to compare and contrast the UNIX/Linux, Microsoft Windows, and MacOS systems. In particular we will contrast and compare the different operating systems in regards to memory management, processing, file management and security. Operating systems at the core is all about the kernel. The kernel in all of the operating systems is the main component that is responsible in the management of memory, processing, file management and security. Contrast and Comparison of Memory Management within Operating Systems Memory management in comparison and contrasts between the different operating systems is due to the way the kernel works in conjunction with the memory. Since each operating system has different kernel’s they each have similar and different ways that they manage memory. Contrasts and comparisons on Mac OS, Windows, and UNIX/Linux are described below. 1. UNIX: Though UNIX and Linux are extremely similar when it comes to how things work internally; there are slight differences that make UNIX distinct from its counterpart. One process that UNIX utilizes is known as swapping; this is done by moving chunks of the Virtual Memory (called pages), out of the main memory and moving others in. In order for this process to work at its best, those pages that are needed must be accessible in the Main Memory at the demand of the CPU. When a page is...

...An operating system, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer would be useless. As computers have progressed and developed so have the many different operating systems. We will talk about the different operating systems and how they compare and contrast as far as their security and memory management. The first operating system we will compare and contrast is Windows Vista and the security features it offers. Windows Vista is an upgrade to Microsoft Windows XP and Windows 2000. When it comes to security and Windows vista, Windows Vista can help protect your PC and the people that use it by providing safety and many security features. One feature includes Bit Locker Drive Encryption. Bit Locker Drive Encryption is a security feature that provides data protection by encrypting all the data that is stored on the Windows Operating System. Windows Vista also has Encrypting File system available which is similar to Bit Locker Drive Encryption except that it is for user level file and folder encryption. Drive Encryption is good if you have two users sharing the same computer. Another security feature for Windows Vista is Parental Controls. Parental Controls are to protect your children and for restricting them to certain areas of your computer. Parental Controls help parents determine which games their children can play or which...

...UNIX is a proprietary brand typically run in large organizational infrastructure. However, many of the UNIX variants are open source that allow users to customize their distribution as they see fit and making copies to install in an unlimited number of machines. UNIX offers a highly stable operating system (OS) that is ideal for full multitasking capabilities while protecting memory to prevent interference with other users. The stability provides greater uptime for increased productivity and less downtime for crash recovery and troubleshooting (Montpelier Open Source, n.d.). UNIX has been the baseline for Internet services and growth where machines on network can operate as clients and servers. Linux is a variant of UNIX and has established itself in the desktop, workstation, and increasingly in the server environments. A key benefit for Linux is the scope of freedom of distributions (distros) that provide many applications, freeware, and add-ons (Stanford University, 2004). Linux is extremely portability to a wide range of new and old machines. The majority of Linux variants are available free or at an economical price compared to Microsoft Windows. Linux is a very secure operating system and although it still can be prone to attacks, it inherently is more secure than Windows. Another huge benefit is the reliability of UNIX and Linux versions that can often run for months without the need to reboot. UNIX and Linux Disadvantages The learning curve for Command Line Interface...

...CRITICAL 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...

...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...

...Windows VS Linux. Ronald Prasad When it comes to computers, majority of the users tend to prefer windows based systems rather than Linux. While Linux has its own qualities like been open source licensed, Windows on the other hand is more user friendly and also has great Hardware supporting compatibilities. Linux is an open source licensed operating system, which basically means that it’s free for everyone to download, free of cost, and modify it without any need of a licenses. Since it’s totally free there is no guarantee of its reliability or customer support to help deal with technically problems. Whereas compared to Windows, which costs about $99-$199 for Windows 8 version, although it does not come cheap, but it provides a guarantee of its reliability and customer support. Windows operating systems are much more user friendly, especially the Windows 8 version, which has excellent user interface, which allows users to navigate, explorer, trouble shoot with very little difficulty. Whereas Linux has a very complex look and puts more emphasis on usage commands in Terminal Window usage instead if using the interface, e.g. To install updates on Linux, sudo apt-get upgrade command must be type in the Terminal Window whereas is Windows getting updates is easily done with just few mouse clicks in the Control Panel. Windows supports most motherboards, mice, hard drives, keyboards, network cards, DVD drives, flash drives and monitors. Since these hardware’s mostly comes with only...

...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.

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.
