Latency

What Internet Latency Means and Why Speed Is Not the Whole Story

A fast internet plan can download a large file quickly and still make a video call feel awkward. A game can react late even when a speed test reports plenty of bandwidth. Sometimes a website pauses before it starts loading, then finishes quickly once it gets going. These experiences make more sense when you separate speed from latency. Internet speed usually describes how much data a connection can move over time. Latency describes delay: how long data takes to travel from one point to another and, depending on the measurement, back again.
