Is there some hypernym word (or phrase) for "input" and "output"?

Like "sibling" for "brother" and "sister", or "parent" for "mother" and "father"?

In a context of electric schemes.

    The acronym I/O is used a lot...

  • Can you give an example for context? I can think of several options that might not be appropriate for all cases.

    I don't know what "electric schemes" means, but input and output are often used to distinguish information travelling in two different directions. So collectively, one could say they're both modes of communication. Apr 16, 2014 at 20:37

From Dictionary of Computer Science

a term used to collectively refer to input and output. Synonym: input/output I/O

However: This term is rarely used. Use other terms that are more specific to your context instead like signal or data.

  • The definition you quote is from input/output... I was really surprised at the existence of transput, but I draw the line at abbreviating it to I/O, honestly.

  • @oerkelens Can't find a dictionary that doesn't redirect the term to Input/Output, but it's not that rare. Anyway, I agree that I/O should be used or some specific term like signal or data, whichever fits the context.

  • I've been in the computer business for over 30 years and I've never heard "transput". 'Not saying it isn't a real word, but I think few people would recognize it. You'd have to explain it. Almost anyone who's worked with computers or electronics would recognize I/O.

I would actually think of the commonly used input/output, or I/O .

Transput may be recognized by some, but I can assure you that plenty of people will not immediately grasp its meaning.

I do admit it is not very original :)

  • Yes, +1. And I/O is more widely used than input/output.

In electrical terms, or at least electrical engineering, a proper term is signal.

    thanks, good idea; I'd like to accept this answer too (together with transput answer), but I can't accept both
