Echtzeit vs sofort
immediately
'sofort' and 'die Echtzeit' both have to do with very little or no delay. 'sofort' is used generally in everyday life when something should happen, or does happen, right away. 'Echtzeit' fits more with technology, media, or data: a system displays or processes something almost at the same moment that it happens. Learners may confuse the words because both express 'without waiting'. In practice: for an action, you usually say 'sofort'; for technical transmission or processing, you say 'in Echtzeit' (in real time).
