An internet speed test measures the connection speed and quality of your connected device to the internet. It does so by running multiple consecutive tests that analyze different aspects of your internet connection, namely ping (latency), download speed, and upload speed. Each of these values represents the connection"s specific qualities, which you can read more about in the paragraph after the next. These should help you understand the final speed test results. But before we get to these, we first want to discuss how to perform each test.

How to test download speed?

The download measurement is performed by opening multiple connections to a server and simultaneously starting the download of a large data file on all connections. This approach ensures that the entire bandwidth of the internet connection is maxed out, and thereby the maximum data throughput can be measured. Recording the data throughput against measurement time finally yields the available internet speed for downloading data.


How to test upload speed?

Upload speed is tested by reversing the sequence of the download analysis. Again multiple connections are opened to the test server. Instead of downloading a file, a large file of random data is created on your device and pushed through all connections to the server. Pushing the data to the server over the network via multiple streams ensures that the maximum throughput is measured. Again, recording the data throughput against time yields the available internet speed for uploading data.


How to test ping?

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.


All these are automatically handled for you when using letspro.edu.vn. But you should take one crucial aspect into account to test speed accurately. Choose the right tool. This depends on the device you want to use, being a phone or tablet, or a computer. To check internet speed on a computer, use your browser and the app on this website. To achieve accurate results on mobile devices, you should download our iOS or Android app, respectively. This is especially important when running a WiFi speed test. Because browsers on mobile devices have poor performance, we suggest using a mobile app written in native code to ensure the most accurate speed test results.


What is download speed?

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. Most often, download speed is denoted in Megabits per second (Mbps or Mb/s), although other forms like Kilobits per second (Kbps or Kb/s) or Megabyte per second (MBps or MB/s) are also common.


What is upload speed?

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.


What is a ping (latency)?

The ping or latency describes the delay of a signal due to the time it takes that signal to travel to its destination. In this context, it represents the time it takes a data package to complete its roundtrip over the network and the acknowledgment from the server that it was received. As a value of time, it is denoted as such, most often in Milliseconds (ms). It"s a value for the responsiveness of your connection.

Why should I test my internet speed?

Because knowing about your connection speeds enables you to a) ensure that you get what you pay for from your internet service provider and b) help you adapt your expectations about what type of applications you can run without issues on your network.


How fast is your internet?

It"s important to understand that different internet speeds are necessary for different usage scenarios. So when you test internet speed, keep in mind that the question "How fast is my internet?" can only be answered in relation to what you want to use the connection for. While simply browsing the web can be achieved with low single-digit megabit per second speeds, streaming Netflix in 4K resolution will need at least a 25Mbps connection speed. Online gaming will primarily be influenced by your ping, with a smaller ping being better while publishing content on the web, like uploading large videos to Youtube will be primarily constrained by your upload bandwidth.
