https://japanese.stackexchange.com/questions/2231/what-is-in-a-d
I thought this was something used in Japanese, but it seems it is terminology used in electronics. Now should i delete my question because the answer reveals that the question was about somethign that probably won't help other people or leave it because when i made i thought it was a valid japanese question?
This can also apply going forward, when answers reveal that the question was too localized.
