...In the world, the most widely used operating system is Windows. In my 3 years in Mercy College I observed that all computers in the school or most personal Laptops of the students is running on version of Windows. But is Windows really the most efficient operating system? The majority of common users will have to agree, but a select few believe otherwise. Many programmers and computer enthusiasts believe Linux to be a far more efficient and usable system because of its flexibility and efficient code. Even so, among the common users, Linux is probably the least known and most underused computer system in the world. The objective of this paper is to determine which system truly is better for users both common and adept. This research compares both operating systems with each other as to determine which is more customizable, easier use, and faster to run. To provide an objective and thorough comparison, this paper looks at key features present in each operating system. After assessing each system, it can be concluded that, although Windows is definitely more widely used than Linux, Linux is the better operating system because of its usability, open source code, and efficient language. However, before analyzing the necessary components, ample background for each operating system must first be provided. The main objective of Windows was "...to provide a personal computing environment for the common user," (Alampay) the common user being people who don't have in-depth knowledge...

...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...

...Purpose and Functions of an Operating System The operating system (OS) is software that manages computer hardware and software resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes a system call to an OS function or be interrupted by it. Operating systems can be found on many devices that contain a computer—from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems include Android, BSD, iOS, Linux, OS X, QNX, Microsoft Windows, Windows Phone, and IBM z/OS.. History 1. Windows - The first Windows system was released in 1985. Originally, it was just a graphical user interface on top of MS-DOS – a state of affairs that lasted until the release of Windows 95, when MS-DOS products were integrated into Windows. Windows 95 was a huge departure from the previous systems and was the first major step...

...Security Mac Viruses Many Mac users believe their systems are impervious to threats. This is a naïve falsity of course because no computer system is invulnerable. It is a known fact that Windows can be very prone to virus infections, but since there are so little Mac viruses, people like to get it in their heads that it isn’t possible. Mac OS X is built on the UNIX kernel, one of the most secure operating systems. UNIX creates a file system in which the user isn’t the most powerful role on the computer and needs root permission to really make any major changes. It is technically more secure, but the only other real benefit is that Apple doesn’t populate a large percentage of the PC marketplace. Apple used to encourage this way of thinking, but after the Flashback virus (Perlroth, 2012), they decided it wasn’t a good idea to lie to their customers. Apple replaced their “Why you’ll love a Mac” website containing “It doesn’t get PC viruses” to “It’s built to be safe” (Mlot, 2012). Since malware really only exploits existing bugs or holes in an operating system, it is up to Apple to fix those holes, and they do a pretty good job of it. But in any case, it’s better to be safe than sorry. Some pretty good Mac antivirus include MacKeeper, Kaspersky, and Trend Micro (Sutherland, 2014). Preventative Maintenance With the threats to OS X made real, there are some simple tricks to keep a Mac up and running. The first of which is the ever-important data backup. Time Machine, is Apple’s...

...An operating system (OS) serves primarily as a translator between the user and the applications and hardware of the machine in use. In this case the PC, tablet or mobile phone. The OS allows the user to easily visualize commands that prompt the software to carry out an array of functions, limited only by the hardware capabilities and the knowledge of its user. During the beginning stages of personal computer (PC) usage, IBM finalized a deal in the early 1980's with the most common household PC OS developer name, Microsoft. It's MS-DOS, then a command line user interface served as the principal design for Microsoft's home PC users released post Apple's Mac OS just 1 year prior. This decision was made after an irreconcilable deal for the 1970's CP/M developed by Greg Kildall. As MS- DOS gained recognition, the onset of home PC user OSs emerged. This report will provide an introduction to the top OSs commonly used in households today such as Mac OS X, Linux, Windows and some of their variants. The functions of these OSs vary in performance across the span of it's developers, however, are relatively the same. These similarities begin with booting the device, providing a Graphical User Interface (GUI) that appeals and adds ease of utilization to the user, as well as the management of system resource, input/output (I/O) and data. All are necessary for a positive experience from even the most novice of users. The similarities of the OSs are what group their developers together...

...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.
