...Windows vs. Linux Enterprise Distribution Recommendation Introduction to UNIX Linux vs. Windows Enterprise Distribution Recommendation X Industries is a large sized business that is in the midst of a decision regarding wither or not to switch their existing Windows-based IT system over to a less proprietary product, Linux. This is no easy choice to make, considering X Industries is currently running 170+ Windows-based servers of various types. Their staff fulfills company operations on these servers with their 750+ array of desktop and laptop computers – all running Windows XP Professional. Linux may just be a little dog in the Microsoft park, but a company that makes the big switch can expect Linux to yield benefits in cost savings, increased security, and arguably better usability. However, each individual enterprise situation is always different, so a cookie cutter solution of which system to use will never suffice. Rather, the numbers through subjects of cost, market share, programming capabilities, software compatibility and availability, and the ever-important user interface will tell the best choice. Cost The only way to evaluate cost is to get down to the basics, and look at the statistics. The first topic of cost will center solely on the price for Windows operating system software, first for the network side, then the node side. Other topics will focus on the cost of the Ubuntu Linux distribution, which will run on the servers and desktops,...

...the creation of the Linux kernel by Linus Torvalds in 1991, many versions of Linux have been created. Due to the open source of the kernel, this gives advanced users the option to alter the kernel to their liking. This, in turn, has yielded a near endless amount of distributions and versions available out there. In my research, I have found the main versions of Linux have derived from Debian Linux, Slackware Linux, or RedHat Linux. However, the first distribution meant for the masses was Yggdrasil Linux (Citation). First, there were versions such as MCC Interim Linux developed by University of Manchester and TAMU developed by Texas A&M, however these were in-house developments not really meant to be widely distributed. Yggdrasil, one of the first widely distributed version of Linux, was described as a Plug and play Linux. Its’ initial release took place in December of 1992, but in the form of an alpha release. The beta version was released in 1993, and the official release the next year in 1994. It was the first Linux operating system distributed via a live CD-ROM. It included an automatic configuration of the software installation, much like we see today, making it very easy for even a novice user to set it up. Yggdrasil was not free, however, the company charged $39.95 per copy (Yggdrasil Computing). After conducting research of the number of distribution of Linux, the exact number could not be pinpointed. There are so many developers tweaking the Linux kernel and submitting...

...Windows XP, Microsoft Windows Server 2003, and Linux operating systems are to consider the system requirements, the different editions available, security features, system features, updates and support, user interface, and cost effectiveness. Moreover, the best fit operating system can be determined depended on the individual’s or organization’s needs. Operating System Requirements Windows XP The system requirements for Windows XP Home Edition and Professional Edition are the same. These requirements are a PC with a 233 megahertz or higher (a 300 megahertz + processor speed is recommended), 64 megabytes (MB) of RAM or higher (128 MB is recommended), 1.5 gigabytes (GB) of available hard drive space, a video adapter and monitor that is Super VGA (800x600) or higher-resolution, CD/DVD-ROM drive, keyboard, and mouse/pointing device. The Windows XP Starter Edition has different system requirements. These are 233MHz processor or better, 256 MB of RAM, Super VGA (800x600) video adapter and monitor, CD/DVD-ROM drive, keyboard, mouse/pointing device, DirectX 9 graphics with 32 MB of graphics memory, and Internet access is highly recommended. Although Windows XP has minimum system requirements, it also has limits on the physical memory. The maximum RAM supported for the Starter Edition is 512 MB. The Professional and Home Editions both have a physical memory limit of 4 GB. Windows XP will not recognize anything over the limits (Microsoft, 2010). Windows Server 2008 The...

RED HAT ENTERPRISE LINUX Costs of Acquisition and Support – A Comparison August 2005 PREPARED FOR Microsoft TABLE OF CONTENTS Main Findings.................................................... 1 Executive Summary ......................................... 2 Analysis ............................................................. 2 License and Subscription Considerations Support Considerations The Total Solution Viewpoint 2 3 6 Main Findings 1. 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.

...1. Why Linux is installed on only a very small fraction of desktop computers Linux is an open source software that can be downloaded free from the internet and used by the end users. Though the original creator of the software gave it freely, some firms have redesigned the operating system and sold it for profit. Other software firms have used it to create their commercial applications such as Oracle. The free availability of Linux has led to its wide use in mobile phones, enterprise software and consumer electronics. Despite its wide use for other purposes, only a small fraction has been used in desktop computers. There are various reasons why this occurs (Gallaugher, 2012). First, it is not easy to use Linux. Compared to other operating...

...use of Linux Server in the business arena has shown new life, due to the scalability and stability of the system and the support it has for other operations as well as the stability of the system and can breathe new life to old systems that no longer are functioning properly with Window applications. Another benefit of Linux is that it is open source and gives each business has the ability to structure or tailor the code to their specific applications. Linux also is not weighted down with license fees or restrictions. Linux overall is a system that is community supported and based not corporation based, which makes the help and support easier to obtain in a matter of minutes and not hours based upon the working hours of a major corporation such as Microsoft. And as all know, 99.99999% of issues always happen or are discovered during the off hours of work. With Linux being run as a server, it can be run without the video requirements that are needed with GUI interfaces. In this aspect, energy can be saved due to the processor not having to work overtime to refresh the pages for every GUI change. Also with Linux, you are not restricted to wait on Microsoft for bug fixes or patches for vulnerabilities. A corporate business can hire in-house Linux programmers, code writers, security personnel and administrators to handle the specific needs of the company, and not rely on outside sources for the support that they are in need of. To maintain stability in a Linux server environment...

...Linux Networking Finals Essay The Domain Name Server Definition: The DNS translates Internet domain and host names to IP addresses. DNS automatically converts the names we type in our Web browser address bar to the IP addresses of Web servers hosting those sites. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. The DNS was designed to resolve or simply match up the IP address associated with the device to the friendly URL name on the other end. The domain name sever’s function in life is to resolve (translate) the user-friendly Web address to the hard to remember IP addresses from somewhere else. Therefore network providers are responsible for having their own DNS databases updated and in sync, with their outside counterparts, when their trying to talk to one another, because only companies IP addresses will match up with one another on the same network. DNS Server Configuration Types: DNS servers can be configured as one of the following types: Caching-only server A caching-only name server maintains a cache...

...PFCH DC Unification Project UNIX and Linux Advantages UNIX has been the cornerstone for infrastructure for the past decade with popular flavors such as Solaris (Craig, 2012). 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...

...system is the most important program that runs on a computer. Computers rely on an operating system to supply the interface for interaction between the user, applications and hardware. The operating system is responsible for booting the computer and manages the file system. It is possible for an operating system to support more than one user task or even CPU (central Processing Unit). All computers must have an operating system it is the program that controls almost all of the functions on your computer. Any decisions that are made during the process of installation will have significant ramifications on how people will use that computer throughout its operational lifetime. Choosing an Operating System There are three main operating systems in use today these are: 1. Microsoft Windows: The current version is Windows 8.1 although this is not the most popular distribution offered by Microsoft, the most widely use is Windows 7 which according to http://www.webopedia.com/TERM/O/operating_system 48.77% of computers are using windows 7 This statistic is verified by http://thenextweb.com/microsoft in 2014 2. Mac OS: Made by the Apple corporation and is very much a proprietary operating system that is made available when apple products are purchased, such as the MacBook Pro laptop. 3. Linux: This is an open source operating system that comes in many different distributions, this is due to the fact that its source code is available for free. This makes the operating...

...◆ 3D Rendering in the Cloud ˇ c Martin D. Carroll, Ilija Hadzi´ , and William A. Katsak Many modern applications and window systems perform three-dimensional (3D) rendering. For a cloud system to support such applications, that 3D rendering must be performed in the cloud, because the end-user equipment cannot be relied upon to contain the necessary rendering hardware. All systems that perform 3D rendering in the cloud are faced with two fundamental and related problems: 1) How to enable an arbitrary number of users to produce rendered pixel streams, and 2) how to transfer those pixel streams out of the server’s frame buffers and into one or more encoders, for transmission to the user. We have implemented a new form of display virtualization that solves both of these problems in a low-level and transparent manner. Using our display virtualization (which we call the virtual cathode ray tube controller (VCRTC)), the cloud system can support an arbitrary number of pixel streams (bounded only by memory and bandwidth resources), and it can dynamically associate those streams with encoders. VCRTCs are completely transparent to the applications: No application needs to be modified, recompiled, or even relinked to use VCRTCs. Because they are low-level and transparent, VCRTCs are also a general mechanism with utility beyond cloud systems. © 2012 Alcatel-Lucent.

...malicious crackers trying to do damage or steal data security is of the utmost importance. One of the best ways to improve security and control is for the company to host their own website internally. The benefit’s for doing this transition will be well worth the effort but there are few points that need to be considered before making the final decision. The goal of this report is to provide information and a guide to the process of creating a secure e-commerce site with minimum downtime. Considerations: There are a few factors that need to be considered before making the move to migrate the website. * Cost-Hardware, labor, software, etc. * Security-physical and physical * Physical space- structure, square footage, additional offices etc. Solution Using the System Development Life cycle we can define an efficient way to meet our set requirements and improve the existing website. Improving on the old foundation we can minimize costs, reduce project time and save the labor costs of having to start from scratch. This way we can focus on only redesigning parts we can’t recycle and improve on what we need to.
