    Explanation
    The correct answer is 15 feet. This is because the maximum length of a parallel cable, which is used to connect devices such as printers and scanners to a computer, is typically limited to 15 feet. Beyond this length, signal degradation and loss of data integrity can occur. Therefore, it is important to ensure that the cable length does not exceed this limit in order to maintain optimal performance and reliability.

    Which printer type relies heavily on static charges to perform its printing operations?

    • Laser

    • Bubble Jet

    • Injet

    • Dot Matrix

    • Daisy wheel

    Correct Answer
    A. Laser
    Explanation
    Laser printers rely heavily on static charges to perform their printing operations. They use a laser beam to create an electrostatic image on a drum, which is then transferred onto the paper using toner. The static charge helps the toner particles adhere to the drum and then to the paper, resulting in high-quality prints. This method allows for precise and fast printing, making laser printers a popular choice for professional and high-volume printing needs.

    Which of the following devices uses IRQ 13 by default?

    • System Timer

    • Mouse

    • Primary IDE Channel

    • Math Coprocessor

    • Com1/Com3

    Correct Answer
    A. Math Coprocessor
    Explanation
    The Math Coprocessor uses IRQ 13 by default. IRQ (Interrupt Request) is a signal sent to the computer's CPU to request attention or to indicate that a specific device needs to be serviced. Each device in a computer system is assigned a specific IRQ number. The Math Coprocessor is a specialized chip that assists the CPU in performing complex mathematical calculations. It requires IRQ 13 to communicate with the CPU and receive instructions. Therefore, the Math Coprocessor uses IRQ 13 by default.

    What type of PCMCIA slots are often used for modem PC cards

    • Type I

    • Type III

    • Type IV

    • Type II

    Correct Answer
    A. Type I
    Explanation
    Type I PCMCIA slots are often used for modem PC cards. These slots are the thinnest and are commonly found in laptops and other portable devices. Type I slots are suitable for smaller devices that require a compact form factor. Modem PC cards are typically smaller in size and do not require the additional space provided by Type II or Type III slots. Type IV slots are rarely used and are larger in size, making them less suitable for modem PC cards.

    After replacing the floppy drive, when you restart the computer, the drive light goes on and stays on. What is the most likely cause of the problem?

    • The floppy drive cable is faulty

    • The floppy drive is not set up correctly in the BIOS

    • The floppy drive data cable is not connected to the motherboard correctly

    • The floppy drive power cable is not connected

    Correct Answer
    A. The floppy drive data cable is not connected to the motherboard correctly
    Explanation
    The most likely cause of the problem is that the floppy drive data cable is not connected to the motherboard correctly. This can result in the drive light staying on because the data cable is responsible for transmitting information between the floppy drive and the motherboard. If the cable is not properly connected, the drive may not be able to communicate with the computer, causing the light to remain on.
