Now you’re in some unspecified distributed model without even defining your variables. Again, models are there to allow us to reason about things without going into every detail. It might make more sense to treat the time to open a connection and the time to send one machine word over an established connection as variables in asymptotic analysis. Then you can reason about sequential processing time, communication volume, and latency in one term.
