Question

Difficulty: MediumNetwork and Peripheral Cables and Connectors

Match each peripheral or network connector on the left with its defining physical characteristic or primary deployment scenario on the right.

  • BNC ConnectorUses a twist-and-lock bayonet mechanism commonly paired with RG-59 or RG-6 coaxial cables for video signals and legacy networks.
  • Micro-USB ConnectorFeatures a 5-pin compact trapezoidal connector header widely used on legacy mobile devices and small peripherals.
  • eSATA ConnectorUses a 7-pin keyed connector interface specifically designed for external SATA storage drives up to 2 meters in length.
  • Lightning ConnectorA proprietary reversible 8-pin connector header used primarily for power delivery and data synchronization on older Apple mobile hardware.

Answer

BNC Connector matches the twist-and-lock bayonet coaxial mechanism; Micro-USB Connector matches the 5-pin trapezoidal header; eSATA Connector matches the 7-pin external storage interface; Lightning Connector matches the proprietary 8-pin reversible Apple interface.
Each connector is correctly matched to its physical pinout, locking mechanism, and intended application: BNC for coaxial video/networking using a bayonet lock, Micro-USB for 5-pin mobile peripherals, eSATA for 7-pin external SATA drive connectivity, and Lightning for Apple's 8-pin reversible mobile interface.

Step-by-Step Solution

1
Identify the physical structure and deployment of BNC
BNC uses a twist-lock bayonet coupler designed for coaxial cables like RG-59/RG-6.
It secures coaxial cable terminations against accidental disconnects.
2
Identify the pinout and form factor of Micro-USB
Micro-USB is a small 5-pin trapezoidal plug.
It was the standard USB interface for mobile devices prior to USB-C.
3
Identify the pin count and role of eSATA
eSATA uses a 7-pin connector designed specifically for external drive attachment.
It provides full SATA bus speeds to external storage enclosures.
4
Identify the proprietary Apple mobile connector
Lightning is a reversible 8-pin digital connector.
It was designed by Apple exclusively for mobile power and data transfer.
