Difficulty: Easy
Correct Answer: Joystick
Explanation:
Introduction / Context:
Correctly identifying legacy connectors is essential for supporting older PCs and peripherals. A 15-pin, two-row D-sub connector is a classic hallmark of the game/MIDI port found on many sound cards and older motherboards.
Given Data / Assumptions:
Concept / Approach:
There are two common 15-pin connectors in PCs: DA-15 (two rows) and HD-15 (three rows). The DA-15 female is associated with the game/MIDI port used for analog joysticks (and via breakout, MIDI). The HD-15 female (three rows) is the VGA video connector. Therefore, a 15-pin, two-row female connector is for a joystick (game port).
Step-by-Step Solution:
Verification / Alternative check:
Photographs or port labeling (a small joystick icon) on bracket I/O shields confirm identification; breakout adapters label MIDI In/Out using the same port.
Why Other Options Are Wrong:
Serial devices use DE-9 or DB-25. Parallel devices use DB-25. MIDI devices alone do not mate directly with DA-15 without an adapter. Video devices (VGA) use HD-15 with three rows, not two.
Common Pitfalls:
Confusing the two-row DA-15 with the three-row HD-15; miscounting rows due to viewing angle.
Final Answer:
Joystick
