A user has a set of earphones that use 1/4-inch mini-jacks as connectors and wants to use them with his computer. You recommend the user purchase an adapter to convert the earphone connector to which of the following:
  1. DVI
  2. RCA
  3. RJ11
  4. 1/8-inch mini-jacks
Explanation
Answer: D - Most computer sound cards use a 1/8-inch mini-jack connector.

Key Takeaway: The user has a larger version of the same connector, and should purchase a 1/4-inch to 1/8-inch converter. The other connection found on many newer computers is S/PDIF-which is a digital audio connection. DVI is a video connection, and RCA, while providing audio, is not often found on computer sound cards.
