See what speeds you can expect from your devices. What factors affect my download and upload speeds? What is latency? Latency ping is how long it takes data to travel from your device to another location and back. High latency can cause issues with video calls or online gaming. More internet help.

During the ping test, the device sends a small data package over the network to the test server on the internet. When the server receives this package, it will send it back to the device, completing the roundtrip. The time it takes the data package to complete the roundtrip is called latency, also known as ping. To achieve an accurate reading, multiple ping tests are conducted consecutively, with the final result being the average of all these tests.

The speed at which your device can receive data from the internet. It's calculated by dividing the total throughput of data in a given time frame by its duration. Therefore its unit is denoted by units of data over time. As opposed to download speed, upload speed characterizes the amount of data your device can send to the internet. It's calculated the same way and is therefore denoted in the same units.
