I say tomato you say "sample resolution"

I have been looking through the new specifications for GCSE computer science starting in September and I have been struck by the lack of agreement on terminology. I’ll give you a couple of examples of this, but I could easily find more.  OCR and Edexcel use the term Sample Rate, whereas AQA use the term Sampling Rate. OCR and Edexcel use the term Bit Depth and AQA uses the term Sample Resolution. Is there any need for this difference? – I’m sure this wouldn’t happen in science.  Why can’t the exam boards agree on the base terminology that they use?  This would be helpful to students who change exam boards, in their transition from GCSE to A level, and students who move schools.
