     If you turn on your computer and receive a parity error, what is the most likely problem?

    • A.

      Your CMOS battery is running low

    • B.

      Your RAM is bad

    • C.

      Your hard drive needs to be formatted

    How many devices can a USB bus support?

    • A.

      No limit

    • B.

      5

    • C.

      16

    • D.

      127

    • E.

      200

    Correct Answer
    D. 127
    Explanation
    A USB bus can support up to 127 devices. This is because the USB specification allows for a maximum of 127 unique addresses to be assigned to devices on a single bus. Each device connected to the bus is assigned a unique address, and the USB controller manages the communication between the devices and the host computer. Therefore, the correct answer is 127.

    User Sally backs up her data on a floppy every evening. After the backup is complete, she forgets to remove the floppy from the drive. Invariably every morning, she is faced with an error message “Non-system disk or disk error”. Which of the following would you consider to help Sally with her problem?

    • A.

      Disconnect the floppy drive

    • B.

      Discharge the CMOS battery

    • C.

      Disable floppy seek during boot up

    • D.

      Ensure the first, second, or third boot device in CMOS setup does not indicate a floppy drive.

    Correct Answer
    D. Ensure the first, second, or third boot device in CMOS setup does not indicate a floppy drive.
    Explanation
    To help Sally with her problem, it is recommended to ensure that the first, second, or third boot device in the CMOS setup does not indicate a floppy drive. This is because the error message "Non-system disk or disk error" is typically displayed when the computer tries to boot from a non-bootable floppy disk. By removing the floppy drive as a boot device, the computer will not attempt to boot from it, preventing the error message from appearing.

     Which connector does the present day SVGA monitor connect?

    • A.

      DB-9

    • B.

      DB-15

    • C.

      DB-25

    • D.

      DB-10

    • E.

      DB-5

    Correct Answer
    B. DB-15
    Explanation
    The present day SVGA monitor connects using a DB-15 connector. This connector is commonly used for video connections and has 15 pins. It is the standard connector for VGA (Video Graphics Array) and supports higher resolutions and color depths compared to older connectors like DB-9 or DB-25.

    Which of the following use a SO DIMM?

    • A.

      Mainframe

    • B.

      A Laptop

    • C.

      A Server

    • D.

      A Desktop Computer

    Correct Answer
    B. A Laptop
    Explanation
    SO DIMM stands for Small Outline Dual In-Line Memory Module. It is a type of memory module used in laptops to provide additional RAM. Unlike desktop computers, which typically use DIMMs, laptops have limited space for components, so they require smaller form factor memory modules like SO DIMMs. Therefore, the correct answer is A Laptop.

    With reference to display resolution, the distance between dots on the screen is measured by ____.

    • A.

      Matrix

    • B.

      Pixels

    • C.

      Dot Pitch

    • D.

      Resolution

    Correct Answer
    C. Dot Pitch
    Explanation
    Dot pitch is the correct answer because it refers to the distance between dots on a screen. It is a measure of the density of pixels on a display, indicating how close the pixels are to each other. A smaller dot pitch means that the dots are closer together, resulting in a higher resolution and sharper image. Therefore, dot pitch is directly related to the clarity and quality of the display resolution.

    You have changed the date and time for Tim’s computer, since it was incorrect. The next morning when Tim boot’s his system, he calls you saying that the system date is again indicating a date 1 year back. What do you suspect?

    • A.

      BIOS is of older version

    • B.

      RAM is insufficient

    • C.

      A CMOS program is infected with virus

    • D.

      Motherboard is faulty

    • E.

      CMOS battery has failed

    Correct Answer
    E. CMOS battery has failed
    Explanation
    The CMOS battery is responsible for powering the CMOS chip, which stores the system's date and time settings. If the CMOS battery has failed, it will not be able to retain the correct date and time settings, causing them to revert back to a default or previous date. This is why Tim's computer is indicating a date 1 year back after he changes the date and time.

    What are the two basic types of partitions?

    • A.

      Primary and extended

    • B.

      Primary and secondary

    • C.

      Primary and logical

    • D.

      Primary and Non-DOS

    Correct Answer
    A. Primary and extended
    Explanation
    The correct answer is primary and extended. In computer storage, partitions are used to divide a physical disk into separate sections. Primary partitions are the main partitions on a disk and can be used to install an operating system. Extended partitions, on the other hand, are used to create logical partitions within them. These logical partitions can be used for data storage or to install additional operating systems. Therefore, primary and extended are the two basic types of partitions.

    While connecting the 40-pin controller cable to an IDE-HDD, the red stripe of the cable will interface with which of the following?

    • A.

      Pin 20

    • B.

      Pin 30

    • C.

      Pin 1

    • D.

      Pin 40

    Correct Answer
    C. Pin 1
    Explanation
    The red stripe of the 40-pin controller cable will interface with Pin 1. This is because the red stripe indicates the first pin or the starting point of the cable. The pins are numbered consecutively from 1 to 40, and the red stripe helps ensure that the cable is connected correctly, aligning Pin 1 on the cable with Pin 1 on the IDE-HDD.

    Dust in a computer actually increases the size of the magnetic fields inside it. This is not good, so you must occasionally dust. What's the best way to do this?

    • A.

      Reverse vacuum

    • B.

      Blow real hard on the system board

    • C.

      Use a lint-free cloth and wipe gently

    • D.

      Any small vacuum device

    • E.

      Non-static compressed air

    Correct Answer
    E. Non-static compressed air
    Explanation
    Using non-static compressed air is the best way to dust a computer. Dust inside a computer can increase the size of magnetic fields, which can be detrimental to the system. Using non-static compressed air helps to effectively remove dust without causing any damage to the components. This method allows for a thorough cleaning while minimizing the risk of static electricity buildup, which can be harmful to the computer.

    Which of the following is an input device only?

    • A.

      SCSI controller

    • B.

      Video card

    • C.

      Modem

    • D.

      Mouse

    Correct Answer
    D. Mouse
    Explanation
    The mouse is an input device because it allows the user to interact with the computer by moving the cursor on the screen and selecting options. The other options listed are not solely input devices. A SCSI controller is a device used to connect and manage SCSI devices such as hard drives and printers. A video card is responsible for generating and outputting images to a display. A modem is used to connect a computer to the internet or other networks.

    Virtual memory refers to what process?

    • A.

      The process of swapping data in and out of reserved memory

    • B.

      Using a file on the hard disk to simulate RAM

    • C.

      Swapping memory from extended to expanded

    • D.

      Using extended memory to simulate expanded memory

    Correct Answer
    B. Using a file on the hard disk to simulate RAM
    Explanation
    Virtual memory refers to the process of using a file on the hard disk to simulate RAM. This means that when the physical RAM (Random Access Memory) of a computer is full, the operating system can temporarily store some data in a file on the hard disk, allowing the computer to continue running smoothly. This process is known as virtual memory because it creates an illusion of having more memory than physically available.
