I agree that we need to get our terminology straight but do not find Peter's suggestions particularly helpful.
Digital technology. Isn't "IT" much more commonly accepted?
ICT If we *have* to because of statute - but then only as an umbrella term. I would prefer "Computing". See argument and references given above.
Embedded technology See my argument against this term at http://edtechnow.net/2012/11/17/digital-literacy-and-the-new-ict-curriculum/ and http://edtechnow.net/2012/10/14/the-dog-that-didnt-bark/.
TEL See my argument against this acronym at http://edtechnow.net/2012/12/05/tel/. I think "education technology" is much better.
