Difficulty: MediumMobile Device Ports and Accessories

Match each mobile device port, connector, or wireless connection technology on the left with its corresponding physical characteristic or primary operational capability on the right.

  • Micro-USBLegacy non-reversible 5-pin trapezoidal connector used on older Android devices and mobile peripherals.
  • USB Type-C24-pin reversible connector supporting high-speed data, high-wattage power delivery, and Alternate Mode video signals.
  • LightningProprietary 8-pin reversible connector designed by Apple for mobile iOS devices.
  • Near Field Communication (NFC)Short-range wireless radio technology operating within a few centimeters, commonly used for mobile contactless payments.

Answer

Micro-USB matches the legacy 5-pin non-reversible trapezoidal connector; USB Type-C matches the 24-pin reversible connector supporting high-wattage power delivery and Alternate Mode video signals; Lightning matches Apple's proprietary 8-pin reversible connector; Near Field Communication (NFC) matches the short-range wireless technology used for contactless payments.
Micro-USB is correctly paired with the legacy 5-pin non-reversible trapezoidal connector. USB Type-C is correctly paired with the 24-pin reversible connector supporting high-wattage power delivery and Alternate Mode display signals. Lightning is correctly paired with Apple's proprietary 8-pin reversible connector. Near Field Communication (NFC) is correctly paired with the short-range wireless radio technology used in contactless mobile payments.

Step-by-Step Solution

1
Identify the physical structure and pin configuration of Micro-USB.
Micro-USB uses a 5-pin micro-B trapezoidal shape that is non-reversible.
This physical pin limit distinguishes Micro-USB from newer reversible connectors like USB-C and Lightning.
2
Identify the features and pin structure of USB Type-C.
USB Type-C features a 24-pin oval, reversible form factor supporting high-speed protocols, Power Delivery, and video transport (Alt Mode).
USB Type-C provides multi-protocol support and high pin density beyond basic USB 2.0 standards.
3
Identify Apple's proprietary mobile connector standard.
Lightning is an 8-pin reversible connector designed specifically for Apple mobile hardware.
Lightning was used extensively on Apple mobile hardware before industry standardization around USB-C.
4
Identify the short-range wireless communication standard.
NFC operates over distances under 4 cm and is primarily used for mobile tap-to-pay terminals.
NFC is designed for close-proximity wireless authentication and transaction data.
