Question

Difficulty: MediumMobile Device Ports and Accessories

An IT technician is updating technical documentation for mobile device accessories and physical port standards used across an enterprise fleet. Match each mobile device port or accessory technology on the left with its corresponding physical characteristic or protocol capability on the right.

  • Qi Wireless ChargingTransfers electrical energy via magnetic induction between transmitter and receiver coils without physical metal contacts.
  • USB Type-C with ThunderboltFeatures a 24-pin reversible physical interface capable of supporting up to 40 Gbps bandwidth, high-wattage Power Delivery, and external display output.
  • Apple Lightning PortFeatures an 8-pin reversible digital physical connector design proprietary to Apple devices.
  • Micro-USB PortFeatures an asymmetrical 5-pin micro-B physical connector limited to legacy USB 2.0 data transfer speeds.

Answer

Qi Wireless Charging matches power transfer via magnetic induction without physical contacts; USB Type-C with Thunderbolt matches the 24-pin reversible interface supporting 40 Gbps bandwidth and video output; Apple Lightning Port matches the 8-pin reversible proprietary connector design; Micro-USB Port matches the asymmetrical 5-pin connector limited to legacy USB 2.0 speeds.
Qi wireless charging operates using electromagnetic induction between internal coils without requiring plug-in wire contacts. USB Type-C with Thunderbolt utilizes a 24-pin reversible connector capable of multiplexing high-speed 40 Gbps data, DisplayPort video, and power delivery. The Apple Lightning connector is an 8-pin reversible proprietary digital interface. The Micro-USB port is an asymmetrical 5-pin connector standard designed for older mobile devices operating at USB 2.0 speeds.

Step-by-Step Solution

1
Analyze the physical connector pin counts and insertion geometry for wired interfaces
Identify USB Type-C as 24-pin reversible, Lightning as 8-pin reversible, and Micro-USB as 5-pin asymmetrical.
Physical pin configurations and symmetry distinguish different mobile physical ports.
2
Evaluate data throughput and protocol tunneling capabilities for each interface
USB Type-C with Thunderbolt support handles up to 40 Gbps throughput, Power Delivery, and DisplayPort signals. Micro-USB handles standard USB 2.0 rates.
Protocol support and transfer rates depend on connector design and internal controller hardware.
3
Evaluate wireless power transmission mechanisms
Qi charging utilizes inductive coupling between magnetic coils to transfer power across short distances.
Inductive wireless charging operates without direct metal-to-metal pin contacts.
