Actually running at the same time is parallelism. "Logically" running at the same time would be "asynchronous". It has to do with the independence of the "processes" themselves.

Could they run in parallel? Or even partially? If it's a yes - then it's already concurrent if it's organized as such. Or it could still just be sequential if that organization hasn't occurred.

So I think of the terminology as a way to frame the independence of parts of a larger process.

That eventually the server and the client are able to connect.
