...Unix/Windows Systems Review for Riordan Manufacturing Micah Gerber POS/420 December 21, 2012 Charles Mathieu Abstract Riordan Manufacturing is the leader in the plastic injection molding industry with facilities in both the United States and China. As a large global operation, having adequate systems in place to support the organization network and databases is of upmost importance. A critique which addresses the benefits and disadvantages of using UNIX or Linux versus Microsoft Windows Server within Riordan Manufacturing will be completed by Team A. Areas to be addressed within the critique will cover security, administration, networking, performance, programmability, and reliability as it relates to UNIX or Linux and Microsoft Windows Server. Riordan Manufacturing currently has a combination of Unix and Windows servers which support the organization, however, the team will recommend that the organization standardize it’s systems to support one platform across the agency. Through this recommendation Riordan’s Manufacturing infrastructure will have one platform Security Review The histories of both Windows and UNIX security development have taken diametric paths. The Windows operating system (OS) is monolithic by design, which means that most of the features are integrated into a single unit and is located into the core of the OS. UNIX, on the other hand is based on the core of the operating systems residing in a distributed manner where...

...Comparison of Windows, Mac OS X and Linux Operating Systems Team A POS/355 March 6, 2015 Memory Management System Memory management is the process of allocating memory during your programs runtime. Memory Management in MAC OS is a multi-core and multi-processor execution that is supported and a programming API, which is called grand central dispatch. It is in the MAC OS. It provides a pool of available threads. There are ways to prevent memory related problems; Freeing data that is still in use, this can cause memory corruption that can result in your application crashing or worse corrupted user data. The MAC operating system can provide most concurrency as possible based on the number of cores available, and those threads depend on the capacity of the system. Windows memory management system is both physical and has virtual memory. It is mainly controlled by the virtual memory managers and pages. “Windows operating system operates on many platforms then it uses page sizes that can range between 4KB to 64KB. So this means that windows virtual memory can control how memory can allocate paging performance” (Stallings, 2013). Committed, Available, and Reserved are three types of regions of space or memory that the operating system can manage. Committed region is space it’s pages that have been stored either in physical or virtual memory. It also allows the process to access the virtual memory pages. Available region is where the address of the process is not being used...

...THE COMPARISONS OF UNIX AND WINDOWS OPERATING SYSTEMS The Comparisons of UNIX and Windows Operating Systems Herlinda Gibson Instructor: Richard Guirguis CIS 155 – Strayer University August 20, 2012 Abstract In today’s world filled with computers and computer technology, having an Operating System (OS) is a must in order to utilize or do anything on your computer but what are the differences in the operating systems and which one would you use? This paper will investigate and analyze some of the similarities and difference between two major Operating Systems; UNIX and Windows XP by comparing and contrasting with some key features such as; cost measurements, market share availability, hardware requirements, file processing, programming capabilities, availabilities of applications software and graphical user interface (GUI) with the hopes of selecting a better computer when purchased. The Comparisons of UNIX and Windows Operating Systems We now live in a world that is basically run by computers and in order to do anything on your computer you will need to have or run some type of Operating System (OS). An operating system is a program that allows you to interact directly with all of the software and hardware on your computer by entering various commands (Haas, 2010). But which operating system should you use? Two major types of Operating Systems are UNIX and Windows. The UNIX operating system which began as early as...

...UNIX, Linux, and Windows Servers Security When comparing Linux/Unix versus Windows platforms for security it is important to take into account the security issues being addressed. The most common types of security breaches in today’s business world are based on social engineering attacks. These attacks are focused on bypassing security measures by tricking users into accomplishing the tasks required by the malicious code. These attacks can introduce numerous types of malicious code into the network ranging from spyware up to and including viruses. When comparing Windows versus Linux/Unix it is important to realize that more security features may be available depending on the exact operating system. This comparison is not to compare specific distributions of Linux/Unix against a specific version of Windows, instead it will compare the core elements that are prevalent in both operating systems regardless of the distribution or version chosen. The first security feature that is discussed is the structure of both operating systems. The difference between Linux/Unix and Windows based on structure is the way configuration for software is approached. Most malicious code in a Windows platform is embedded into the registry. The registry is a single location that stores every configuration setting for software installed on the machine. This allows a standard location for malicious code to target on a windows machine. Whereas Linux/Unix does not have a registry, instead it uses...

...Introduction The most commonly known Operating Systems (OS) today are UNIX, Linux, MacOS, and Windows. These operating systems all behave in their own way and similar in others. This paper will discuss this comparison of how these operating systems utilize memory, process handling, file management, and security. Memory Management Each operating system is required to allocate a certain amount of memory for the operating system itself for the processes that are being used or executed. There are two places memory exists: physically on the motherboard of the computer and within the operating system itself. When the operating system dynamically divides the memory usage between these two areas, this is called memory management. Each operating system manages memory different from the others; however they all follow some basic rules of memory management. All of the operating system’s memory management in general follows these requirements: relocation, protection, sharing, logical organization, and physical organization (Stallings, 2015). Relocation of memory is the process that allows the operating system to move a process or file from physical memory to virtual memory and back again, depending on the need for that data. Virtual memory exists within the operating system which uses the hard drive to store temporary information and physical memory is located on the motherboard of the computer. While the process is in memory, protection of that area needs to be enabled to...

...NORTHWEST SAMAR STATE UNIVERSITY Graduate School and Training Academy Calbayog City Course: Master of Science in Information Technology Subject: Client Server Computing Professor: Mr. Donald M. Patimo, MPM Student: Riva A. Gatongay CASE STUDIES IN THIN CLIENT ACCEPTANCE The challenge facing the acceptance of Thin Clients is a combination of architectural design and integration strategy rather than a purely technical issue, and a careful selection of services to be offered over Thin Clients is essential to their acceptance. I. INTRUDUCTION It is generally accepted that in 1993 Tim Negris coined the phrase “Thin Client” in response to Larry Ellison’s request to differentiate the server centric model of Oracle from the desktop centric model prevalent at the time. Since then the technology has evolved from a concept to a reality with the introduction of a variety of hardware devices, network protocols and server centric virtualized environments. The Thin Client model offers users the ability to access centralized resources using full graphical desktops from remotely located, low cost, stateless devices. While there is sufficient literature in support of Thin Clients and their deployment, the strategies employed are not often well documented. To demonstrate the critical importance of how Thin Clients perform in relation to user acceptance this paper presents a series of case studies highlighting key points to be addressed in order to...

...INDRODUCTION Networking operating system It is the software that runs on a server and enables the server to manage data, users, groups, security, applications, and other networking functions.[2] The network operating system is designed to allow shared file and printer access among multiple computers in a network, typically a local area network (LAN), a private network or to other networks. The most popular network operating systems are Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, and Novell NetWare. Multiuser File Sharing A network operating system manages concurrent requests from clients and provides the security necessary in a multiuser environment. A file sharing component is installed in each client machine that interacts with the server to share files and applications as well as devices on the network such as printers, faxes and modems. Peer-to-Peer In a Peer-to-peer network operating system users are allowed to share resources and files located on their computers and access shared resources from others. A peer-to-peer network sets all connected computers equal; they all share the same abilities to utilize resources available on the network. Client/Server Client/server network operating systems allow the network to centralize functions and applications in one or more dedicated file servers. The server is the center of the system, allowing access to resources and instituting security. The network operating system...

...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. Instead, there is a single root filesystem whose path is “/”. If you must use the Windows analogy...
