"Dych chi'n deall yr iaith rhaglennu?"
Translation:Do you understand the programming language?
What does 'programming language ' mean, refer to, don't understand the concept in English let alone Welsh.
A 'language' used for programming computers, etc. There is a lot of information about the topic on the web.
A computer only understands 0 and 1. As a human being it's hard to remember commands made up of series of 0s and 1s, so the programmers started naming the series (add, store, fetch) to make it easier. When they started creating names for longer series of commands (the loop concept in particular) they started calling it "programming language". Every app, every modern computer program, every browser, every modern operative system have been created using a programming language, and there are at least 40 different languages (I've only used 18 of them, but I can't say I really know more than 6 or 7).
