Difficulty: EasyMobile Device Ports and Accessories

Match each mobile device connector or accessory technology on the left with its primary physical or operational characteristic on the right.

  • LightningProprietary 8-pin reversible connector used primarily on legacy Apple mobile devices
  • USB-CIndustry-standard 24-pin reversible connector supporting power delivery, video output, and high-speed data
  • Micro-USBLegacy 5-pin asymmetrical (non-reversible) connector commonly found on older Android devices
  • NFCUltra-short-range wireless connection method used primarily for contactless payment systems and tap-to-pair setup

Answer

Lightning pairs with the proprietary 8-pin reversible connector; USB-C pairs with the 24-pin reversible connector supporting power, video, and data; Micro-USB pairs with the 5-pin asymmetrical legacy connector; NFC pairs with the ultra-short-range wireless connection method for tap payments.
Each connector standard and wireless protocol is correctly matched to its physical pin layout, insertion orientation, or proximity transmission capability.

Step-by-Step Solution

1
Examine physical connector design, pin arrangement, and reversibility.
Lightning is an 8-pin reversible plug, Micro-USB is a 5-pin directional plug, and USB-C is a 24-pin reversible multi-function plug.
Differentiating connector physical specifications allows technicians to select correct cables and adapters.
2
Identify wireless interface operational range and primary deployment scenario.
Near Field Communication (NFC) operates at extreme close range for contactless payments.
NFC is designed specifically for short-distance proximity communications rather than wide-area wireless connections.
