Learn what the numbers in a speed test mean before using them to diagnose a problem. Download and upload describe data transfer in different directions, while ping and jitter describe aspects of response timing. Units also matter: a rate shown in megabits per second is different from a file size shown in megabytes. These explanations introduce the terms used throughout the site and show why one headline speed cannot describe every application. Start with the measurement you want to understand, then use the relevant troubleshooting or activity guide when you are ready to investigate your connection.
