Understanding how your computer talks to the internet and why response time matters
Ping measures how long this entire conversation takes
Imagine you're standing at one side of a canyon and you shout "Hello!" to someone on the other side. They hear you and shout "Hello!" back. Ping is like measuring how long it takes for your voice to travel there and their response to come back to you.
In computer terms, ping is a simple test that measures how long it takes for a small message to travel from your computer to another computer on the internet and back. That's it – nothing complicated!
When you "ping" a website like Google, your computer sends a tiny message asking "Are you there?" Google's servers respond with "Yes, I'm here!" and your computer measures how long that entire conversation took.
The name comes from sonar technology used by submarines. Just like a submarine sends out a "ping" sound and listens for the echo to detect objects underwater, your computer sends out a digital "ping" and waits for the response.
Ping measures latency – which is just a fancy word for "delay" or "response time." It tells you:
For most everyday internet activities, ping doesn't matter much. But here are situations where it becomes important:
Online games need quick responses. High ping causes lag, making games feel sluggish or unresponsive.
Ideal: Under 50msVideo conferencing needs low latency for natural conversations without awkward delays.
Ideal: Under 80msWeb pages load faster with lower ping, especially for interactive elements.
Acceptable: Under 200msOnce streaming starts, ping doesn't matter much. It's more about bandwidth.
Not critical for streamingThe simplest way is to use our ping test tool. Just enter a website name and click "Run Tests" – we'll show you the ping time along with other useful information.
If you're feeling adventurous, you can open your computer's command prompt and type:
When you run a ping test, here's what you'll typically see:
The important number is the "time" value – that's your ping in milliseconds. In this example, the ping is around 23ms, which is excellent!
