Difficulty: MediumNetwork and Peripheral Cables and Connectors

Match each network or peripheral connector on the left with its correct physical specification or intended application on the right.

  • USB 3.0 Type-B connector9-pin connector with a blue insertion block, commonly used on external hard drive enclosures and USB 3.0 printers.
  • Lightning connectorProprietary 8-pin reversible connector used primarily on legacy Apple mobile devices for power delivery and data transfer.
  • RJ11 connector6-position modular connector used to connect analog telephone lines and legacy DSL modems to wall jacks.
  • Micro-USB connector5-pin compact trapezoidal connector widely used on older Android mobile phones, digital cameras, and power banks.

Answer

USB 3.0 Type-B pairs with the 9-pin connector containing a blue block used for high-speed peripherals; Lightning pairs with Apple's proprietary 8-pin reversible connector; RJ11 pairs with the 6-position modular connector for telephone lines and DSL modems; Micro-USB pairs with the 5-pin compact trapezoidal connector for legacy portable devices.
Each connector matches its distinct specification: USB 3.0 Type-B has 9 pins with a blue block for high-speed peripherals; Lightning is Apple's 8-pin reversible mobile connector; RJ11 is a 6-position modular jack for telephone/DSL wiring; Micro-USB is a 5-pin trapezoidal connector for legacy portable electronics.

Step-by-Step Solution

1
Analyze USB 3.0 peripheral connector pinouts and color indicators.
USB 3.0 Type-B has 9 pins and a blue insert to distinguish SuperSpeed performance from 4-pin USB 2.0 Type-B connectors.
USB 3.x standards specify blue color coding and additional pins for full-duplex SuperSpeed signaling.
2
Identify mobile connector pin counts and proprietary interface designs.
The Lightning connector is Apple's 8-pin reversible design.
Lightning features 8 gold contacts on both sides of a flat connector head, allowing insertion in either orientation.
3
Differentiate telephone wiring modular jacks from Ethernet jacks.
RJ11 is the 6-position modular connector for telephone landlines and DSL modems.
RJ11 uses a smaller 6-position housing (6P2C/6P4C) compared to the 8-position (8P8C) RJ45 used in Ethernet networking.
4
Identify legacy USB mobile port shapes.
Micro-USB is the 5-pin trapezoidal connector.
Micro-USB 2.0 features 5 pins within a compact trapezoidal housing to prevent upside-down insertion.

Key Concept

Distinguishing network and peripheral connectors by physical shape, pin count, color coding, and functional applications.
