    In which of the following is the output from a power supply rated?

    • Voltage.

    • Watts.

    • Hertz.

    • Ohms.

    Correct Answer
    A. Watts.
    Explanation
    Power supplies are rated in Watts. Watt is the SI derived unit of power, equal to 1 Volt * 1 Ampere.

    When connecting the power cable of an AT power supply to the motherboard, which two wires on the power connectors (P8/P9) should be together?

    • The green wires.

    • The white wires.

    • The black wires.

    • The brown wires.

    Correct Answer
    A. The black wires.
    Explanation
    When connecting the power cable of an AT power supply to the motherboard, the two wires on the power connectors (P8/P9) that should be together are the black wires. This is because the black wires are the ground wires, and connecting them ensures proper grounding and electrical continuity between the power supply and the motherboard.

    What do you call the part of a CD-ROM drive's head assembly that moves across the disk to read it?

    • Read/Write Actuator.

    • The Mechanical Frame

    • The Head Actuator.

    • The Disk Spindle.

    Correct Answer
    A. The Head Actuator.
    Explanation
    The head actuator is the device that physically positions the read/write heads over the correct track on the surface of the disk. It is called the same for CD-ROMs, hard drives and floppy disks.

    Which of the following components on the motherboard usually house the IDE connectors?

    • PCI bus.

    • North Bridge.

    • ISA bus.

    • South Bridge.

    Correct Answer
    A. South Bridge.
    Explanation
    The South Bridge is generally used for slower devices such as USB ports, IDE drives, and ISA slots.

    What is the clock speed of the AGPx8 expansion slot?

    • 66 MHz

    • 133 MHz

    • 266 MHz

    • 533 MHz

    Correct Answer
    A. 533 MHz
    Explanation
    The AGPx8 has a clock speed of 533 MHz and has a transfer rate of about 2.1GB/s.

    Rate this question:

  • 7. 

    Which of the following is the SCSI ID number generally recommended for the CD-ROM?

    • ID 0.

    • ID 5.

    • ID 2.

    • ID 3.

    Correct Answer
    A. ID 3.
    Explanation
    Every other device can be set to any number as long as it's not in use. It is a recommended practice in the IT community to set the SCSI ID number for CD-ROM drives to 3.

    Rate this question:

  • 8. 

    Which of the following are SCSI types that allow for 16 devices, including the adapter, to be connected on a single shared cable?

    • Ultra Wide SCSI

    • Fast SCSI

    • Ultra SCSI

    • Fast Wide SCSI

    • Ultra 2 SCSI

    Correct Answer(s)
    A. Ultra Wide SCSI
    A. Fast Wide SCSI
    Explanation
    Wide SCSI buses support 16 devices, rather than the 8 devices specified in regular SCSI.

    Rate this question:

  • 9. 

    The new Certkiller .com trainee technician wants to know which of the following has a transfer rate of 40 Mbps and a maximum cable length of 12 meters. How will you reply?

    • SCSI-2

    • Ultra 2 SCSI

    • Ultra Wide SCSI

    • Fast SCSI

    • Ultra SCSI

    Correct Answer
    A. Ultra 2 SCSI
    Explanation
    Explanation: Ultra2 SCSI (8-bit) is capable of 40MB/s transfers, with a maximum cable length of 12 meters (39 feet), also used the same connectors as Fast-10.

    Which of the following BEST describes the difference between the "baby" AT and ATX motherboards?

    • The "baby" AT motherboard allows for the installation of more than two full-length expansion cards whereas the ATX motherboard allows for only one or two.

    • The processor, memory, and expansion slots are all in line with each other on a "baby" AT motherboard, whereas the ATX motherboard has the processor and memory slots at right angles to the expansion cards.

    • The ATX motherboard allows for the installation of more than two full-length expansion cards, whereas the "baby" AT allows for only one or two.

    • The "baby" AT motherboard has a 20-pin power connector while the ATX has a 12-pin power connector.

    Correct Answer(s)
    A. The processor, memory, and expansion slots are all in line with each other on a "baby" AT motherboard, whereas the ATX motherboard has the processor and memory slots at right angles to the expansion cards.
    A. The ATX motherboard allows for the installation of more than two full-length expansion cards, whereas the "baby" AT allows for only one or two.
    Explanation
    On the AT motherboards the processor, memory, and expansion slots are all in line with each other. Because the processor and memory were in line with the expansion slots, only one or two full-length cards could be used. Also, the processor was far from the power supply's cooling fan and would therefore tend to overheat unless a heat sink or processor fan was directly attached to it. To overcome the limitations of the "baby" AT design, the ATX motherboard was designed. The ATX has the processor and memory slots at right angles to the expansion cards. This puts the processor and memory in line with the fan output of the power supply, allowing the processor to run cooler. And, because those components are not in line with the expansion cards, you can install full-length expansion cards in an ATX motherboard machine.
