Jitter Internet Test -

Jitter is a measure of the packet delay variation in an internet connection. It's calculated by measuring the time difference between packets of data sent over the internet. High jitter can cause problems with real-time applications like video conferencing, online gaming, and voice over IP (VoIP) calls.

Even with high speeds, video streams may freeze momentarily while the player waits for delayed packets. Interpreting Your Jitter Test Results jitter internet test
