Shit to remember 1A

  • What is the nominal data rate of a USB port supporting Gen 3.2 2×1?

    • 10 Gbps

  • A technician connects a single port on a graphics card to two monitors using two cables. What type of interface is being used?

    • Both the DisplayPort and Thunderbolt interfaces support this type of daisy-chaining.

  • True or false USB-C ports and connectors are compatible with Apple Lightning connectors and ports.

    • False. An adapter cable is required.

  • A technician has removed an adapter card from a PC. Should the technician obtain and install a blanking plate to complete the service operation?

    • Yes. The fan system draws cool air across the motherboard and blows out warm air. Large holes in the chassis disrupt this airflow. Also, dust will be able to settle on the system components more easily. A blanking plate covers the empty slot in the case.

  • You are labeling spare parts for inventory. What type of USB connector is shown in the exhibit?

    • USB 2.0 Type B micro

  • A technician is completing a storage upgrade on an older computer. Examining the power supply, the technician notices that only two of the five plugs of the type shown in the exhibit are connected to devices. What is the purpose of these plugs, and can some be left unconnected?

    • A Molex cable is a power cable used for storage devices that require more power than can be supplied over most internal bus types. Unused connectors do not pose any problem (though they should be secured with cable ties to minimize disruption to air flow).

  • Most drives use what power connectors currently?

    • SATA power connectors

  • High-Definition Multimedia Interface (HDMI)

    • Digital audio/video interface developed for consumer electronics and computer equipment use.

  • Molex is what type of connector format?

    • Legacy

  • DisplayPort

    • Digital audio/video interface developed by VESA. DisplayPort supports some cross-compatibility with DVI and HDMI devices.

  • Thunderbolt

    • Thunderbolt can be used as a display interface (like DisplayPort) and as a general peripheral interface (like USB 3). The latest version uses USB-C connectors.

  • Lightning

    • connector still being used for older versions of Apple products.

  • Serial Advanced Technology Attachment

    • SATA = widely used interface for hard disks on the desktop and laptop computers

    • What two kinds of data connectors is used with one device per port?

      • 7-pin data connector

      • 15-pin power connector

    • What are the three SATA standard bandwidths?

      • 1.5 Gb/s

      • 3 Gb/s

      • 6 Gb/s

    • Are external drives supported? if so how?

      • Yes, external drives are also supported via the eSATA interface. Note: designed for external connectivity

    • Molex connector

      • Legacy power connector for internal devices such as hard drives and optical drives.
