Latency and variability are key aspects of your internet connection that you can measure with a ping and jitter speed test. A lower value indicates a faster response time, which is essential for smooth online activity, since ping, or latency, gauges how quickly data travels to a server and back. In order to measure the stability of a connection, jitter measures its consistency. Real-time communication such as video calls and online gaming can be disrupted by high jitter, resulting in lag and poor performance. For streaming, gaming, and other online activities to run smoothly, understanding these metrics is crucial.
