...Operating Systems most favored by fortune 500 companies are Windows, Red Hat Linux and AIX. Operating Systems perform basic task that supports the use of input, the printers, drivers, keyboard and the display screen. The operating systems support different programs and users running on it at the same time. It also supports the security and user abilities. Operating systems provide software platforms on top of applications, like Java, Visual Basic etc. These applications have to be written to run operating systems. There are several choices of operating systems DOS, OS/2, Windows, AIX, and Linux. The two main operating systems are Windows and Linux/Unix. “And they have a competitive history and future” (Haas). Before we get into the technicalities of either operating system, let’s examine the environment that these two systems evolved from, or the culture from whence they came, if you will. “Corporate culture pertains to the identity and personality of the company we work with, either in the private or public sectors. All companies have a culture; a way they behave and operate. They may be organized and disciplined or chaotic and unstructured. Either way, this is the culture the company has elected to adopt” Brice, (2012). “Microsoft may appear to some people as a company without culture, but that impression changes upon entering the Sigma Building, which houses Microsoft Research Asia. Chatting with the great minds at Microsoft Research Asia, one is reminded...

...Eichling UNIX®/Linux® versus Mac® versus Windows® There are several computer operating systems available on the market, and it is sometimes difficult to choose. Therefore, it is important to compare the system capabilities to make the decision easier. The three biggest players in the operating systems market are UNIX®/Linux®, Mac®, and Microsoft® Windows® with Windows® holding the largest market share (Boitor & Brătucu, 2011). These three operating systems are capable of multi-processing and have similar capabilities; however, and it is important to compare and contrast how they handle memory management, process management, file management, and security, which are critical system functions. Discussing memory management, which is a vital component in operating systems, is first. Memory Management Memory management refers to the way a system makes use of the computer’s RAM (Random Access Memory). Many of the operating systems in use on computer systems have positives and negatives in their use of memory attributes. “Memory management is usually divided into three areas: hardware, operating system, and application…although the distinctions are a little fuzzy. In most computer systems, all three are present to some extent, forming layers between the user's program and the actual memory hardware” (Ravenbrook Limited, 2001, p. 1). There are several types of memory, including main memory, file system memory, and swap space (Red Hat Enterprise Linux Deployment Guide, 2012). How...

...Operating Systems Analysis Paper An operating system is the meat and potatoes of any computer system, without it there would be no computer system. Its’ main functions are input/output, peripherals and providing a platform for which all applications and processes can run. This software tells your computer how to function and is the primary interface for which the computer is controlled. Operating systems also commonly referred to as OS are the basis for the security of systems. In today’s technology the operating systems use GUI’s which are graphic user interfaces that work to manage multiple processes at one time almost seamlessly. We will evaluate the most common operating systems found on the Internet today. The purpose for having an OS is to handle multiple programs that may be installed on a computer. The three most common operating systems for use on the Internet are Windows, Linux and the Mac OS X. Making the decision about which is best for you, means that you will need to be aware of the functionality and compatibility of these operating systems that are available for the Internet. First, let’s evaluate Windows, the first version was just called Windows and developed in 1985 as an add-on for MS-DOS, which is one of the dinsoaurs of operating systems.

...Understanding the System Properties of the Computer By: Natasha R. Spann Microsoft Office Application on Demand Instructor: Carol Edwards-Walcott May 22, 2016 The most important window you should be able to locate in your computer is System Properties. It provides the most vital information about your computer. By reviewing this window System Properties, you will learn the exact Operating System the computer runs. The Operating System is listed under “Windows edition”. Then you will see the title “System”, the speed of your processor is listed, the amount of Installed memory (RAM), and then the System type. Then you will have the title “Computer name, domain, and workgroup settings”. All of these details are very important when using the computer. The Operating System (OS) is the most essential software on the computer. The OS manages the hardware and software. The Operating System gives direct access to the storage, central processing unit (CPU), and memory, so that different programs can work properly. Without the OS the Computer will operate properly. The operating system determines what your computer can or cannot actually do because each OS has different features, options, applications, compatibilities and even the user interface may change. My current computer has Windows 8.1 as the operating system. Within Windows 8.1 the user interface is much different than the previous Windows 7. After, the first initial installation of Windows 8 certain programs did...

...Exemplary Final Report Research on Understanding Microsoft’s Operating System’s Weak Smartphone Market Share Marketing Research Executive Summary – Background Smartphone ownership and usage is at an all-time high. Unfortunately, Microsoft’s operating system (OS) has never had a competitive market share in the cellular industry. Google’s Android and Apple’s iOS have dominated the market despite Microsoft’s efforts to increase their popularity—and ultimately their demand. Underlying reasoning for Microsoft’s shortfalls in the cellular industry were unclear at first. Predicted problems included Microsoft’s absence when the smartphone craze arose, and their inability to effectively market their competitive advantage over the competition. Today, Microsoft owns only roughly 4% of the U.S. smartphone market share (Lella.). Based on research, our group wanted to know what should be done to recover Microsoft’s awareness in the smartphone industry as a competitive smartphone operating system. Research objectives were aimed at discovering college students’ general perspectives concerning smartphone brands, and the major motives for students to purchase Android or iOS based smartphones. The last research objective was designed to learn the reasoning for Microsoft’s low popularity in the cellular market, and what could potentially be done to produce more demand. Executive Summary – Results After conducting research, the results coincided with the predictions...

...choosing this topic is for personal understanding on how much UNIX performance monitoring differs from the monitoring of Windows based computers. This research paper is not to compare the two systems but to gain an understanding of how UNIX monitors performance. I don’t have any personal experience with working with UNIX systems, but as always eager to gain insight of different operating systems. The first thing I would like to discover is some of the common performance problems encountered caused by software, hardware and the combination of the two, the different terminologies associated with the processes via hardware or software, and finally what different utilities are used for monitoring these problems. We all know that UNIX has been around since the early 1970’s and the developments of performance tools have been around for a long time to enable system administrators in tuning systems for optimal performance. Operating systems performance problems normally involves process management, memory management, and scheduling. The object of performance on UNIX based systems is to determine the amount of time the operating system spends during scheduling and the amount of time for applications to run (Unknown, 2003). Windows based systems establish an appropriate ration between time in application mode and time in system mode (Unknown, 2003). I will get more into UNIX based systems and how these monitoring tools are used to keep our UNIX based system running at optimal performance...

...creation of the first operating system in 1981 by Microsoft at IBM’s request. By1983, PC Magazine labeled the SCAMP as the “first personal computer” and a “revolutionary concept”. Since then there have been numerous advancements in the ongoing creation of computers during which the operating system evolved into what is known today as Windows, Linux, and the Mac OS X. But what makes these great machines operate? What is their purpose? What are their functions? Multimedia designers, graphic artists, and musicians would argue that the Mac OS X is superior. Gamers, programmers, and businesses might prefer Linux. The average household would say that Windows is the way to go. This being said, we will look into what makes each of these systems differ from one another and look at the pros and cons of each. To get an understanding of the different operating systems we need to understand the actual meaning of an operating system. The definition of an operating system is a collection of software that coordinates and provides common services for computer programs. Without the operating system, the computer and software would be useless. With a better understanding of what an operating system is, we can now look at the operating systems purpose or functionality. An important function of the operating system is resource management. This means monitoring the central processing unit, memory, disk drives, and printers. It also provides a user interface. The operating system manages input/output...

And open system that scales has an advantage over a closed and self-contained economic system. 2. Middleware in the context of distributed application is software that provides services beyond those provided by the operating system to enable the various components of a distributed system to communicate and manage data. Middleware also does support and simplifies complex distributed applications. 3. The thin client is run on the user's local computer and is focused on displaying results to the user. The business logic is located in server applications running on a server. Thin clients request functions from the server application, which is itself a multithreaded application capable of working with many concurrent users. The server application is the one that opens connections to the database server and can be running on the same server as the database, or it can connect across the network to a separate server operating as a database server. 4.

...vision through technical innovation and business strategy, he and his partner Paul Allen built one of the world’s largest software company, Microsoft. Two computer genius and enthusiasts met at Lakeside school and went into business together. According to Biograpy.com, in 1981, while working together with Apple to develop software for Macintosh computers, Gates recognized a threat to Microsoft’s MS-DOS operating system that primarily used text and keyboard as opposed to Apple’s system that used a mouse to drive a graphic interface, displaying text and images on the screen. Knowing and understanding where the market was going, Microsoft launched Windows systems that looked very similar to the Apple’s Macintosh system. Gates, who had advised Apple to license their software, which Apple ignored, took full advantage of the situation. Though Apple sued, Microsoft was able to prove that although there were similarities between the two, their function was different. Unlike other software companies, Microsoft understood the market and where it was heading. It made its Operating system compatible with other PC giving Microsoft an absolute advantage. Gates was genius in refusing to sell the...

...various running programs to optimize overall system performance. Memory management resides in hardware, in the OS (operating system), and in programs and applications.” Also, memory management is simply stated as the act of managing computer memory. Now that we have an understanding of what memory management is we can discuss the requirements for three different components hardware, OS, and application level. First, we will look at memory management requirements (MMR) for hardware. Hardware is considered to be physical components of a computer that store data like Random Accessed Memory (RAM), memory caches, and flash-based solid state drives. I located the following information about MMR at, http://www/memorymanagement.org/mmref/begin.html, “Memory management at the hardware level is concerned with the electronic devices that actually store data. This includes things like RAM and memory caches.” RAM can be upgraded, which in turn will speed up the computer. Next, we will discuss MMR for the OS. MMR for the OS is different than it is for hardware. In the OS, memory management involves the allocation (and constant reallocation) of specific memory blocks to individual programs as user demands change. The OS uses algorithms to decide which unused block to place the information. Two broad tasks that have to be accomplished, each process must have enough memory in which to execute and the different types of memory in the system must be...

...Operating systems are an essential part of any computer system. Similarly, a course on operating systems is an essential part of any computer science education. This field is undergoing rapid change, as computers are now prevalent in virtually every arena of day-to-day life—from embedded devices in automobiles through the most sophisticated planning tools for governments and multinational firms. Yet the fundamental concepts remain fairly clear, and it is on these that we base this book. We wrote this book as a text for an introductory course in operating systems at the junior or senior undergraduate level or at the first-year graduate level.We hope that practitioners will also find it useful. It provides a clear description of the concepts that underlie operating systems. As prerequisites, we assume that the reader is familiar with basic data structures, computer organization, and a high-level language, such as C or Java. The hardware topics required for an understanding of operating systems are covered in Chapter 1. In that chapter, we also include an overview of the fundamental data structures that are prevalent in most operating systems. For code examples,we use predominantly C, with some Java, but the reader can still understand the algorithms without a thorough knowledge of these languages. Concepts are presented using intuitive descriptions. Important theoretical results are covered, but formal proofs are largely omitted. The bibliographical notes at...
