Difficulty: MediumMobile Device Ports and Accessories

Match each mobile device port standard or wireless connection type to its corresponding technical characteristic or capability.

  • LightningProprietary 8-pin reversible connector used primarily on legacy Apple mobile devices
  • USB Micro-BNon-reversible 5-pin trapezoidal connector commonly used on older Android mobile devices
  • USB-CIndustry-standard 24-pin reversible connector supporting power delivery, high-speed data, and Alternate Modes
  • Near Field Communication (NFC)Short-range (~4 cm) high-frequency wireless technology used for tap-to-pay and accessory pairing

Answer

Lightning pairs with the proprietary 8-pin reversible connector description; USB Micro-B pairs with the non-reversible 5-pin connector description; USB-C pairs with the 24-pin reversible connector supporting Alternate Modes; and Near Field Communication (NFC) pairs with the short-range wireless payment and pairing technology description.
Each connection type is paired accurately with its physical design, pin count, vendor context, or wireless operational range. Lightning is Apple's proprietary 8-pin reversible connector; USB Micro-B is the older non-reversible 5-pin standard; USB-C is the modern 24-pin reversible standard supporting power and display features; and NFC provides short-range wireless communication for mobile payments and device pairing.

Step-by-Step Solution

1
Analyze physical connector characteristics including pin counts, vendor exclusivity, and reversibility.
Lightning is identified as an 8-pin reversible proprietary connector, USB Micro-B as a 5-pin non-reversible trapezoidal connector, and USB-C as a 24-pin reversible universal connector.
Physical pin configuration, shape, and vendor design distinguish wired mobile ports.
2
Distinguish physical ports from wireless short-range accessory communications.
NFC is identified as a contactless wireless standard operating over very short distances (~4 cm) for mobile tap-to-pay transactions and pairing.
Wireless mobile accessories rely on RF standards such as NFC or Bluetooth rather than physical pin contacts.
