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 BIOSExplanation
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.Rate this question:

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 FormattingExplanation
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.Rate this question:

- A.
Normal Mode
- B.
Compete Mode
- C.
Safe Mode
- D.
VGA Mode
Correct Answer
B. Compete ModeExplanation
The correct answer is "Compete Mode" because it is not a recognized boot mode in Microsoft systems.

Chap 12Which of the following is not a configuration option for computer video?
- A.
PinCushion
- B.
Contrast
- C.
Trapezoid
- D.
Rhombus

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 LinesExplanation
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.Rate this question:

Chap 12Which of the following is considered a diagnostic utility in the Microsoft operating system.
- A.
REGEDIT
- B.
CACL
- C.

- D.
CHKDSK
Correct Answer
D. CHKDSKExplanation
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.Rate this question:

- A.
Device Manager
- B.
Task Manager
- C.
Program Manager
- D.
Control Panel
Correct Answer
A. Device ManagerExplanation
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.Rate this question:
