Show Answers:

  1. What is the most common form factor used today?
  2. The first ATX power supplies and motherboards used a single power connector. What is the name of this connector?
    P1 connector
  3. What, if supported by the OS, can turn off the power to a system after the shutdown procedure is done?
    Soft switch
  4. What form factor is a major variation of ATX and addresses some technologies that have emerged since the original development of ATX?
  5. What reduces the total cost of a system by reducing the number of expansion slots on the motherboard, reducing the power supplied to the board, and allowing for a smaller case size?
  6. This form factor is commonly used in slimline and all-in-one cases but can fit into any FlextATX, MicroATX, or ATX case that follows the ATX 2.03 or higher standard.
  7. This form factor was designed by Intel in 2003 for flexibility and can be used by everything from large tower systems to those ultrasmall systems that sit under a monitor.
    BTX (Balanced Technology Extended)
  8. This motherboard form factor design focuses on reducing heat with better airflow and improved fans and coolers.
  9. This motherboard form factor for low-end personal computer motherboards was developed by Intel in 1998 to improve on an older and similar form factor called the LPX form factor.
    NLX (New Low-profile Extended)
  10. Where is the riser card located on an NLX motherboard?
    On the edge
  11. What houses the power supply, motherboard, expansion slots, and drives?
    Computer case (sometimes called chassis)
  12. What is the first LGA socket?
    LGA775 socket
  13. This chipset supports the Intel LGA1366 socket, the Core i7 processors, and PCI Express Version 2
  14. This bus does not run in sync with the system clock, and always connects to the slow end of the chipset, the South Bridge
    Expansion Bus
  15. Which statement is true?
    A. The frequency state is a command to the processorto wait for slower devices to catch up.
    B. The first PCI bus had a 32-bit data path, supplied 5V of power to an expansion card, and operated at 33MHZ
    C. A Universal PCI card uses a 3.3-V only
    D. PCI- X introduced the 64-bit, 3.3-V PCI slot
    B. The first PCI bus had a 32-bit data path, supplied 5V of power to an expansion card, and operated at 33MHZ
  16. Another name for throughput
  17. _______ is focused on technologies that target the server market
  18. What slot contains a single lane for data, which is actually 4 wires?
    PCI Express x1
  19. Which PCIe version double the frequency of the PCIe bus, theoretically doubling the throughput?
    PCIe version 2
  20. True or False:

    You can use a riser card in other systems besides NLX to extend an expansion slot.
  21. True or False:

    APG 3.0 cards can be installed in an AGP 1.5v slot.
    True but signals are put on the bus using 0.8v
  22. What card has part of its audio, modem, or networking logic on the card, and part on a controller on the motherboard?
    Rise Card
  23. True or False:
    A CNR slot is smaller than a PCI slot but about the same height
  24. What are ports coming directly off the motherboard called?
    Ports coming directly of the motherboard are called on-board ports or integrated components.
  25. This may have several internal connectors, including parallel ATA connectors (also called EIDE), a floppy drive connector, serial ATA connectors, SCSI connectors, or a FireWire (IEEE 1394) connector.
  26. What program can easily make changes to the setup values stored in CMOS RAM?
    BIOS Setup or CMOS Setup
  27. Some older motherboards and expansion cards store setup data using this.
    dual inline package (DIP) switch
  28. True or False:

    You have to replace an entire motherboard if a port fails.
  29. What is considered opened or closed based on whether a cover is present on two small posts or metal pins that stick up off the motherboard.
  30. True or False:

    Setup information about the motherboard can be stored by setting a jumper on (closed) or off (open)
