Why is latency and bandwith separated? If latency is delay of data, and bandwith is data over time, shouldn’t one affect another? If it takes 5s for a car to start, and 10s to reach it’s destination, then the average speed would be spread out across the whole 15s. Should this not be the same?

Consider conventional mail (via a post office). This a high latency, high bandwidth type of communications. It takes a few days to get a shipment somewhere, but that shipment can contain almost unlimited amounts of data.

Contrast this with SMS (text messaging). This is fairly low latency – your text message arrives almost immediately – but low bandwidth (you can’t send all that much data).

Another way to consider this:

Latency is *responsiveness*. It’s how long it takes to get a reply once I send a message.

Bandwidth is *volume*. It’s how much information I can send over time.
