    Chap 12Your laptop has shared video memory. You want to increase the amount of memory available tot he video card from 32MB to 64MB. Where do you do this?

    • A.

      Video applet in Control Panel

    • B.

      Moving a jumper on the video card

    • C.

      System BIOS

    • D.

      You can't reallocate memory

    Correct Answer
    C. System BIOS
    Explanation
    In order to increase the amount of memory available to the video card from 32MB to 64MB, you need to access the System BIOS. The System BIOS (Basic Input/Output System) is a firmware that is responsible for initializing the hardware components of the computer, including the video card. By accessing the System BIOS, you can modify the settings related to the video card and allocate more memory to it. This will allow the video card to have a larger amount of memory available for processing graphics and improving performance.

    Chap 12What is the term for an operating system independent operation that ties a hard drive to it controller card?

    • A.

      High-Leval Formatting

    • B.

      Low-level Formatting

    • C.

      Parititioning

    • D.

      Scrubbing

    Correct Answer
    B. Low-level Formatting
    Explanation
    Low-level formatting is the term for an operating system independent operation that ties a hard drive to its controller card. This process prepares the hard drive for use by dividing it into sectors and tracks, and it establishes the necessary structures for data storage and retrieval. It is performed at the factory or by specialized software and is different from high-level formatting, which is done by the operating system and prepares the drive for file system usage. Partitioning is the process of dividing a hard drive into multiple logical sections, while scrubbing refers to the process of securely erasing data from a hard drive.

    Chap 12Which of the following is not a Microsoft boot mode?

    • A.

      Normal Mode

    • B.

      Compete Mode

    • C.

      Safe Mode

    • D.

      VGA Mode

    Correct Answer
    B. Compete Mode
    Explanation
    The correct answer is "Compete Mode" because it is not a recognized boot mode in Microsoft systems. The other options, Normal Mode, Safe Mode, and VGA Mode, are all valid boot modes that serve different purposes. Normal Mode is the default mode for starting up the system, Safe Mode is a diagnostic mode used to troubleshoot issues, and VGA Mode is a mode that uses basic video graphics drivers.

    Chap 12Which of the following is not a configuration option for computer video?

    • A.

      PinCushion

    • B.

      Contrast

    • C.

      Trapezoid

    • D.

      Rhombus

    Correct Answer
    D. Rhombus
    Explanation
    The given question asks for a configuration option for computer video, and the options provided are PinCushion, Contrast, Trapezoid, and Rhombus. PinCushion, Contrast, and Trapezoid are all valid configuration options for computer video, but Rhombus is not. A rhombus is a geometric shape and is not related to video configuration. Therefore, Rhombus is the correct answer as it does not belong to the category of computer video configuration options.

    Chap 12Which of the following is not an example of a standard input output connector.

    • A.

      1/8 inch jack

    • B.

      Mini-DIN

    • C.

      D-subminiature

    • D.

      USB

    Correct Answer
    A. 1/8 inch jack
    Explanation
    The 1/8 inch jack is not an example of a standard input output connector. The other options listed (Mini-DIN, D-subminiature, USB) are all commonly used connectors for input and output devices. The 1/8 inch jack, also known as a headphone jack, is primarily used for audio output and is not typically used for other types of input or output connections.

    Chap 12Which system resource allows an expansion card, for instance, to signal the CPU that it requires some of the CPUs time.

    • A.

      I/O memory

    • B.

      DMA channels

    • C.

      IRQ Lines

    • D.

      Memory address

    Correct Answer
    C. IRQ Lines
    Explanation
    IRQ (Interrupt Request) Lines are system resources that allow expansion cards to signal the CPU that they require some of the CPU's time. When an expansion card needs the CPU's attention, it sends an interrupt request signal through an IRQ line. The CPU then stops its current task and handles the interrupt, giving priority to the expansion card's request. This allows for efficient communication between expansion cards and the CPU, ensuring that they can share the CPU's time effectively without causing conflicts or delays.

    Chap 12Which of the following is considered a diagnostic utility in the Microsoft operating system.

    • A.

      REGEDIT

    • B.

      CACL

    • C.

      CALC

    • D.

      CHKDSK

    Correct Answer
    D. CHKDSK
    Explanation
    CHKDSK is considered a diagnostic utility in the Microsoft operating system. CHKDSK stands for "Check Disk" and is used to check the integrity of the file system and the hard drive for errors. It scans the disk for bad sectors, fixes logical file system errors, and recovers readable information. It can also be used to repair and recover data from corrupted disks. Therefore, CHKDSK is a valuable tool for diagnosing and fixing issues with the operating system's file system and hard drive.

    Chap 12What is the name of the utility that allows you to check hardware resources and alter them, if allowed.

    • A.

      Device Manager

    • B.

      Task Manager

    • C.

      Program Manager

    • D.

      Control Panel

    Correct Answer
    A. Device Manager
    Explanation
    Device Manager is the correct answer because it is a utility that allows users to check the hardware resources of their computer system and make changes to them if permitted. It provides a detailed view of all the hardware devices installed on the system, including information about their drivers, status, and properties. Users can use Device Manager to update drivers, enable or disable devices, uninstall devices, and troubleshoot hardware issues. Task Manager, Program Manager, and Control Panel are not specifically designed for managing hardware resources, making Device Manager the most appropriate choice.

      802.11g

    Correct Answer
    D. 802.11g
    Explanation
    802.11g is the correct answer because it is a wireless communication standard that supports data transfer speeds of up to 54Mbps. This standard operates in the 2.4GHz frequency range and is backward compatible with the 802.11b standard. It offers faster data rates and improved performance compared to 802.11b, making it suitable for applications that require higher bandwidth, such as streaming video or online gaming. Bluetooth is a different wireless communication standard that operates in the 2.4GHz frequency range but has a lower maximum data transfer rate of around 3Mbps. 802.11 is a general term for wireless LAN standards, and 802.11b is an older standard that supports data transfer speeds of up to 11Mbps.
