    Chapter 8. Operating Systems > Answers and Explanations

    Answers and Explanations

    1.B. Windows Aero is Microsoft’s new visual experience. It features translucent windows, window animations, three-dimensional viewing of windows, and a modified taskbar. You can make modifications to the look of Aero by right-clicking the desktop and selecting Personalize. Then select Windows Color and Appearance. There you can modify features such as the transparency of windows. Note: Aero is not available in Windows Vista Home Basic.
    2.A. If you are using a Windows-based operating system, you have used this at one time or the other. You can view all files on the system as well as view network drives.
    3.C. Windows XP uses My Network Places to manage dial-up and local area network connections. When you open My Network Places, you see a list of network connections and shared folders on the network, including those located on the local computer and on remote computers.
    4.A, C. While you install the Windows operating system to the new drive, you must go through the partitioning and formatting steps. Almost all drives are not prepared to accept an operating system right out of the box. However, initialization happens automatically during the OS install. The primary hard drive (the one with the OS) does not need to be initialized. But, other hard drives that are added afterward need to be initialized within Disk Management.
    5.C. For you to view the installed devices, you need to instruct the user to go to Device Manager and see if there are any errors on the display adapters.
    6.C. The minimum processor requirement for Windows Vista is 800MHz. However, Microsoft recommends 1GHz or higher. 133MHz is the minimum processor requirement for Windows 2000 Professional, and 233MHz is the minimum for Windows XP.
    7.C. The minimum RAM requirement for Windows Vista is 512MB. However, Microsoft recommends 1GB of RAM or higher. 64MB is the minimum RAM requirement for Windows XP/2000.
    8.D. To manage network connections while in the Network window, click the Network and Sharing Center button. After that window opens, click the link for Manage Network Connections.
    9.C. Linux uses the KDE GUI. Windows and Mac OS have their own GUI, and DOS is text-based with no GUI at all.
    10.A, C, D. Windows and Linux distributions such as Ubuntu are meant to run on PCs. Personal computers can use hardware from many manufacturers with Intel being one of the most common. Mac OS X is written for Macintosh computers that use Intel hardware as well. Mac OS version 7.6 was the first version to be dubbed “Mac OS”; it was written for Motorola-based processors.
    11.B, C, D. Windows XP, Vista, and 7 are all heavily used in the U.S. However, Windows 2000 only has a very small amount of people still using it.
    12.C. A single hard drive can contain up to four primary partitions.
    13.A. To do anything with the drive, it must first be initialized. Then, it can be partitioned and formatted in that order. An OS is not necessary if the first hard disk already has one.
    14.C, D. Windows Vista and Windows 7 can extend partitions, but Windows 2000 and XP cannot.
    15.B, C, D. NTFS supports file-level security, EFS, and disk quotas. However, although NTFS has a practical limit of 2 TB for partitions, it can theoretically be extended as far as 16 exabytes.
    16.C. Windows 7 64-bit versions require a minimum of 2GB of RAM. 32-bit versions require only 1GB of RAM.

    Case Study 1 Solution

    1: For example, a Windows Vista computer could be analyzed in the following way:

    1. Identify the operating system: Click Start, and then right-click Computer and select Properties. This displays the System window, and the Windows edition is shown at the top.

    2. Identify CPU, RAM, and HD: The CPU and RAM can also be determined in the System window. However, hard drive space has to be located in either Disk Management or in Windows Explorer.

    You can find out automatically whether your operating system can be upgraded to Windows 7. Factors that determine this include the CPU speed, type of CPU (32-bit or 64-bit), amount of RAM, and available hard disk space.
