    Which technology would be best to use for drive redundancy and data protection?

    • CD

    • DVD

    • PATA

    • RAID

    • SCSI

    Correct Answer
    A. RAID
    Explanation
    RAID (Redundant Array of Independent Disks) is the best technology for drive redundancy and data protection. RAID combines multiple physical drives into a single logical unit, providing fault tolerance and improved performance. It offers various levels of redundancy, such as mirroring and parity, to ensure data is protected against drive failures. By distributing data across multiple drives, RAID provides increased reliability and data availability. Therefore, RAID is the most suitable technology for achieving drive redundancy and data protection.

    What is the function of a fan on top of a heat sink?

    • To cool the memory modules;

    • To move the heat away from CPU;

    • To draw cool air into the computer case;

    • To provide a water-cooling system for extremely fast CPUs.

    Correct Answer
    A. To move the heat away from CPU;
    Explanation
    The function of a fan on top of a heat sink is to move the heat away from the CPU. A heat sink is designed to absorb and dissipate heat generated by the CPU, and the fan helps in this process by blowing air over the heat sink. This airflow helps to carry the heat away from the CPU, preventing it from overheating. By constantly moving the heat away, the fan helps to maintain the CPU's temperature within safe operating limits.

    A tehnician creates a simple circuit that has a 9V light bulb attached to a 9V battery. The power output of the light bulb is 100W. Which equation should be used to calculate how much current in amps is required to archive the full 100W output from the 9V bulb ?

    • I=P/V = 100W/9V= 11.11A

    • I=P*V=100W*9V=900A

    • I=(P/2)*V=50W*9V=450A

    • I=P*2*V=100W*(9v+9v)=8100A

    Correct Answer
    A. I=P/V = 100W/9V= 11.11A
    Explanation
    The equation I=P/V is used to calculate the current in amps required to achieve the full 100W output from the 9V bulb. By dividing the power (100W) by the voltage (9V), we get the current in amps (11.11A).

    A technician receives a complaint of poor image quality after the user changes the native resolution. While investigating the complaint, the technician discovers there is a mismatch between native mode and the native resolution of the peripheral. Which item is configured incorrectly?

    • DLP

    • LCD

    • Printer

    • Scanner

    Correct Answer
    A. LCD
    Explanation
    The technician discovers that there is a mismatch between the native mode and the native resolution of the peripheral. Since the complaint is about poor image quality, it can be inferred that the peripheral in question is a display device. Therefore, the item that is configured incorrectly is the LCD, as it is the type of display commonly associated with native resolutions and image quality.

    Which memory module has a front side bus speed of 200MHz?

    • DDR-333

    • DDR-400

    • DDR-667

    • DDR3-667

    • PC100 SDRAM

    Correct Answer
    A. DDR-400
    Explanation
    DDR-400 is the correct answer because it has a front side bus speed of 200MHz. The front side bus speed is the speed at which the memory module communicates with the processor. DDR-400 has a front side bus speed of 200MHz because DDR stands for Double Data Rate, which means that the actual speed is twice the front side bus speed. Therefore, DDR-400 operates at 200MHz.

    How many FireWire devices can be supported by a single FireWire port?

    • 12

    • 25

    • 32

    • 54

    • 63

    • 127

    Correct Answer
    A. 63
    Explanation
    A single FireWire port can support up to 63 FireWire devices. This is because FireWire uses a daisy-chain topology, where devices are connected in a series. Each device in the chain can pass along the signal to the next device, allowing multiple devices to be connected to a single port. However, there is a limit to the number of devices that can be connected in a single chain, and in the case of FireWire, that limit is 63.

    Rate this question:

  • 18. 

    Which type of computer resources are direct lines to the processor and are used by computer components to request attention from the CPU?

    • DMAs

    • I/O Addresses

    • IRQs

    • Memory Addresses

    Correct Answer
    A. IRQs
    Explanation
    IRQs, or Interrupt Requests, are direct lines to the processor that are used by computer components to request attention from the CPU. When a device needs to communicate with the CPU, it sends an interrupt request through an IRQ line. This allows the device to interrupt the current task being performed by the CPU and request immediate attention. IRQs are important for managing and prioritizing different tasks and ensuring efficient communication between computer components and the processor.

    • 8 Pin

    • 9 Pin

    • 15 Pin

    Correct Answer(s)
    A. 4 Pin
    A. 6 Pin
    Explanation
    The 1394a interface, also known as FireWire, has two connector types: 4 Pin and 6 Pin. These connectors are used to connect devices such as cameras, external hard drives, and audio interfaces to a computer. The 4 Pin connector is smaller and is commonly used for portable devices, while the 6 Pin connector is larger and provides power to the connected device. These connectors allow for high-speed data transfer and are commonly found on older computers and devices.

    Which three system resources are commonly used for communication between the CPU or memory and other components in the computer? (Choose three.)

    • IRQ

    • DMA

    • UDP

    • I/O Address

    • USB

    • PnP

    Correct Answer(s)
    A. IRQ
    A. DMA
    A. I/O Address
    Explanation
    IRQ, DMA, and I/O Address are commonly used system resources for communication between the CPU or memory and other components in a computer.

    IRQ (Interrupt Request) is used to signal the CPU that a device needs attention or that an event has occurred. It allows devices to interrupt the CPU and request immediate attention.

    DMA (Direct Memory Access) is a feature that allows certain devices to transfer data directly to or from the computer's memory without involving the CPU. It helps in improving the efficiency of data transfer.

    I/O Address (Input/Output Address) is a specific address range used by devices to communicate with the CPU. It allows devices to send and receive data to and from the CPU.

    These three resources play a crucial role in facilitating communication and data transfer between various components of a computer system.
