A lecture at my university is titled "Communications In English for Engineers".
Somebody from my year stated that 'communications' (in plural) relate to telecommunication and generally engineering/science discipline, rather than process of communicating between two or more entities (people/devices/anything else).
However, my brief Google research have not confirmed this. Most dictionaries queried about 'communications' in plural show a page for this term, but description seems more like one for 'communication'.
Could you then please explain:
- What does 'communications' mean?
- Is this term interchangeable with 'communication'?
- Optionally: where does this difference (if there is one) come from?
