Windows Operating System
Exercise 3.1 1. Summarize the four phases of the Windows boot process in your own words. 2. Over the years, Microsoft has consistently updated the Windows operating system with new versions. Compare and contrast the features of Windows 7 and Windows Vista. 3. The Windows operating system has specific requirements that must be met in order to install it on a PC or mobile device. Which three most important hardware devices must be considered before you install Windows 8, 7, Vista, or XP on a computer? Explain why these three devices are important in general. 4. Mobile computing is the way of the future and so are mobile operating systems. Describe the features and benefits of the two major mobile operating systems, Android and Apple iOS.

1. The first phase would be to power up the computer by pressing the power button, doing so the power button creates an electrical impulse that instructs the motherboard to power on the power supply to begin the computers boot up sequence. The second phase after your initial startup power sequence is the BIOS activates and runs the power-on self-test (POST) that checks the hardware of the computer such as the CPU, RAM, video interface, hard drives, USB interfaces, and other integrated ports and interfaces, making sure everything is working properly, after that the BIOS displays an option for you to press if you choose to enter into the BIOS settings. The third phase of the computer boot up process is now the BIOS is ready to run the computers operating system (OS), the BIOS searches for the Master Boot Record (MBR), the MBR contains information about the partition on the hard drive, usually being the first; C: drive, if everything runs successfully the MBR boots up the boot manager file in the root of the partition drive; C: drive, loading up the operating system for the computer.…...

...Researching operating systems I am choosing Windows XP for the basic low end computer because the system requirements are fairly low and it will work on just about any personal computer that is being used today. The operating system I am choosing for the high end computer is Windows 7. Its requirements are tailor-made more for the newer and higher end computers. Some of the computers that are out there will not be able to run windows 7. Windows XP system requirements are a Pentium 233 megahertz processor, at least 64 megabytes of system memory, at least 1.5 gigabytes of hard disk space, CD-ROM or DVD drive, video adaptor, and a monitor with a screen resolution of 800x600 or higher. Windows XP doesn’t have a very memory intensive graphical user interface either. If you are upgrading from Windows 2000 you probably won’t notice too much of a difference as far as the general look and feel of the operating system. You will have to activate it soon after you install the program to keep it from deactivating. Windows XP also has better security and protection than previous versions. Windows 7 system requirements are 1 gigahertz or faster processor, 1 gigabyte of system memory for 32 bit systems and 2 gigabytes of system memory for 64 bit systems, 16 gigabytes of hard disk space for 32 bit systems and 20 gigabytes of hard disk space for 64 bit systems, support for DirectX 9 with windows display driver model 1.0 and 128 megabytes of memory for the Aero theme desktop, a......

...Paper: Operating Systems Analysis Paper POS/355 November 7, 2011 Jeff Rugg Introduction The operating system, commonly known as OS, is the brain or the center of all computer systems. It controls the input/output and controls various tasks of the hardware. Apart from serving as a go-between for application programs and the hardware of the computer, the OS also consists of information and programs while providing general services to make sure that several software applications can operate accordingly. Operating systems can be found in almost any type of a computer device such as personal computers, supercomputers, cellular telephones, and video game consoles as stated by Linux Systems (2011). As the research was being conducted for this paper, it raised a question whether the internet uses the operating system? It proved to be a challenge to actually pin point the most common operating systems on the Internet, but as the research continued, it was obvious that these three, Windows, Mac OS X, and Linux are considered to be the most common operating systems used on the Internet today. Background of each Operating System Windows Privately owned operating systems, Microsoft Windows is generally used on personal computers and as of today, the most commonly used version is Windows XP with the new version of Windows 7 for personal computers and Windows Server 2008 R2 for servers is entering the market.

But one can always go to the Microsoft site and type SQL Server Express in the Bing search box. This will list the current download URL. I selected SQL Server Express because it is readily available and because it provides a more realistic and complete Database Management System experience than Microsoft Access which is often used in classroom settings. SQL Server Express lets the students experience managing multiple databases in a single management environment. The SQL Express Management Studio also contains a query analyzer that allows students to easily run SQL queries and view the results. Unlike Access, SQL Server Express supports Stored Procedures and Triggers. Finally, again unlike Access, SQL Express provides a rich set of security features that are more typical of commercial database management systems. If, however, an instructor prefers or must use Microsoft Access, Appendix one explains how to substitute it for SQL Server. The appendix notes the variations in practices and examples in each chapter required for the adaption. Other database software such as MySQL or Oracle could also be adopted for use with the book. Although the book uses SQL Server Express, its focus is on the process of developing and designing a database. The principles of this process are......

...Operating Systems Christy Kegley IT/282 3/2/2014 Carlton Foster Operating Systems * Provide a brief history of three operating systems. The top three operating systems are; Windows XP, Windows Vista, and Linux. “Windows XP is the first Windows OS to allow multiple users to log on simultaneously to the OS, each with their own applications open. Although Windows XP was first released with some bugs, the second service pack (Service Pack 2) resolved most of these problems. XP underwent three service packs. It is an extremely stable OS and was popular in both the home and corporate markets” (Guide to Managing and Maintaining Your PC, Eighth Edition, Andrews, pg. 1116). This programs allows users to do many things that others might not allow like older versions of Windows. Windows Vista is the newest version of Windows. This program is not very popular with some people because there is a lack of compatibility with other programs, also it slows performance. “The first problem is partly caused by hardware manufacturers not providing Vista drivers for their devices that were originally sold with XP drivers. The second problem means that many low end desktop and laptop computers can’t run Vista. And the slow performance of Vista is partly due to the many unnecessary features (fluff) it offers; these features weigh heavy on system resources. Vista comes in five versions: Windows Vista Home Basic, Home Premium, Business, Enterprise, and Ultimate. (Vista......

...Operating Systems’ Differences There are three operating systems, Windows, Linux, and Mac OS. The purpose of the operating system as defined in (dictionary.com) is the collection of software that directs a computer’s operations, controlling and scheduling the execution of other programs, managing storage, input/output, and communication resources. Its abbreviation is OS. Mac OS used by Apple on Macintosh computers is used by 10% of Americans. It uses a GUI (graphical user interface) that is run by a keyboard and mouse. But is not a PC and is not compatible with PC hardware. Previously, it ran on a Motorola processor but its successors run on an Intel platform. Mac OS is a favorite of graphic artist, musicians, and multi-media designers. It uses a point release system. It uses Safari and Mozilla Firefox for internet connection. Mac OS has a specialized version of the program developed for the iphone and ipod. Linux operating system is similar to Unix in design but is meant to be run on PC’s, gaming consoles, DVR’s, and mobile phones. 1 to 2 % of the U.S. population use Linux on personal computers. It was written by Linus Torvalds and can be freely downloaded by anyone. Several companies distribute their own versions of Linux called Ubuntu, SuSE, Red Hat, and Knoppix. Linux’s GUI runs on top of the system, free of open software. ......

A security flaw according to "Apple Security Flaw: What You Need To Know" (2014), "The flaw is in the way the operating system provides the essential services, known as secure sockets layer (SSL) or transport layer security (TLS). These two layers of security allow information to be transmitted worry-free between browsers and web servers, or between a mail server and mail client. SSL is in the form of encryption, which scrambles data sent over a network to keep it private. The second layer involves verification that the server is authentic." With the heighten computer security regarding vulnerabilities, the increase of user awareness and training users to not click on particular links is difficult yet feasible. Although most operating system has computer security protection, the tasks of protecting the systems from vulnerabilities are a daunting task because the operating systems are unique. Security flaw in Microsoft and Mac OS X® A known security flaw in Windows is called the Freak.

...NT1110_StudentName_Module1_Lab.doc 3/21/15 An operating system takes input in the form of zeros and ones -- bits -- and runs them through various circuits and processors, the hardware behaves according to built in rules. We define these rules using gates, which take input and produce an output in a structured way. The operating system allows complex programs to access hardware to get results. Only the hardware's physical properties can limit what programs can do. You could design an operating system by physically programming it into a computer's circuits. This would require building electrical pathways using millions of gates. But such an operating system would be slow and you would need the patience of Jonah to use it. That's why operating systems like Mac OS X and Windows are software. Software is flexible and hardware is not -- you can make changes to software with updates. To do the same with hardware would mean switching out physical chips and circuit boards. Operating systems are like the manager for a computer, it’s the job of the OS to monitor what software needs and what the hardware can provide. When you run applications on your computer, the OS allocates the resources necessary to complete the task. That can include processing power, memory and computer storage access, among other things. Ideally the OS will make sure that your computer's hardware is never overtaxed. ...

Everybody knows what is a Hard Disk or Hard Drive let me refresh your mind, with a simple explanation: Hard Disk/ Drive, is a device for storing and retrieving digital information, primarily computer data. It consists of one or more rigid rapidly rotating discs (platters) coated with magnetic material, and with magnetic heads arranged to write data to the surfaces and read it from them. With that been said, now move forward with Operating System and Hard Disk/ Drive. I would like to recommend you the best operating system is DOS (Disk Operating System), why? Because has everything you need. Let me tell you a little more about DOS. Disk Operating System: Most often abbreviated as DOS, refer to operating system software used in most computers that provides the abstraction and management of secondary storage devices and the information on them (e.g., file systems for organizing files of all sorts). Such software is referred to as a disk operating system when the storage devices it manages are made of rotating platters, such as floppy disks or hard disks. In the early days of microcomputers, computer memory space was often limited, so the disk operating system was an extension of the operating system. This component was only loaded if needed. Otherwise, disk access......
