Explain latency by taking one example

Question

disatance between client and server is  2km then the time to send data from client to server and server to client is how much?

Answer 1

Would recommend you read some background on network latency. There are multiple factors and not just the number of kms between the client and server.

Network latency concepts are not specific to AppWarpS2 but are across any client-server communication setup over the internet.
