    Correct Answer(s)
    A. SATA
    C. PATA
    Explanation
    SATA and PATA are the two correct answers, (ATA/IDE) is the 40-pin interface used by most CD and DVD drives and a few early Blu-ray drives. SATA is the seven-pin high-speed serial interface used by late-model high-performance DVD drives and most Blu-ray drives. PATA and SATA are also used by hard disks and some types of removable-media drives. IrDA is an infrared (IR) interface used for line-of-sight printing and data transport between some computers (mostly older laptops) and printers. USB (Universal Serial Bus) is used for almost all external devices, from printers and multifunction devices to hard disks, optical drives, and flash memory devices. Although some USB adapter cards feature a single internal port, that port is intended for use by drive-bay mounted USB hubs or card readers.

    You have just installed a CD-ROM drive to your computer. You want to listen to music so you insert a music CD into the drive. Windows Media Player starts up and you can see a song title and the elapsed time of the song within the player. Everything looks correct; however, for some reason you cannot hear the music. What could be the problem?

    • A.

      The power cable is not connected to the CD-ROM drive

    • B.

      You need to connect the CD audio cable to the sound card

    • C.

      You need to go the manufacturer's website for an updated CD-ROM driver

    • D.

      The CD is faulty

    Correct Answer
    B. You need to connect the CD audio cable to the sound card
    Explanation
    If you want to play music CDs through your sound card’s speakers, you might need to connect a CD audio patch cable. One end connects to the CD-ROM drive and the other end connects to the CD audio port on the sound card or motherboard. Older drives support a four-wire analog cable, whereas newer drives support both the four-wire analog and newer two-wire digital cable. If the power cable wasn’t connected, the drive wouldn’t have opened when you inserted the disc. CD-ROM drives normally don’t need drivers installed; they are installed automatically by Windows. However you might need a soundcard driver. If the CD was faulty, Windows Media Player would not have played the song, and you wouldn’t have seen the song title or the elapsed time of the song.

Plug in the drive, and it appears in My Computer or Windows Explorer. PCIe is an internal expansion bus used by video cards and other secondary adapter cards.

    You have just installed a new floppy drive on a computer. You notice that when you turn the computer on, the drive light stays on. What could be causing this problem?

    • A.

      The cable has been installed incorrectly

    • B.

      The drive is faulty

    • C.

      The drive has been installed improperly

    • D.

      The BIOS has not been configuration properly

    Correct Answer
    A. The cable has been installed incorrectly
    Explanation
    Floppy drive data cables that are reversed (pin 1 to pin 33) at either the floppy drive interface on the motherboard/floppy controller card or at the drive itself will cause the drive light to come on and stay on. To correct this, turn off the system, remove and reattach the data cable correctly, and restart the system.
