What Is A Speed Test And What Is It For?

When we talk about speed tests, we are talking about a tool that we can consult when we find ourselves in extreme situations, due to a failure with respect to the internet connection.

That is why when you have a problem with the connection, you must go to a speed test which will carry out an exhaustive review of your connection. In order to really understand what it is about and clarify your doubts, you will need to know some terms, and thus carry out the speed test with full knowledge.

What do you need

What do you need to apply a speed test?

Before being able to understand what a speed test is and what it is for, it is necessary that you know some terms that will complement your understanding of said test, and those are:


Instructions for performing a speed test

Here we will leave you the instructions of the processes that you must follow correctly, to carry out a speed test:

You should know that:

  1. The speed test is basically based on downloading and uploading some file packages to the server. Depending on how long it takes to upload and download the packet, it will return the connection speed.
  2. The speed test is not only responsible for downloading the package that we already mentioned, but it is also responsible for determining which is the provider, and the company that provides us with the internet.
  3. This test also analyzes the proximity of other servers to ours. Depending on the location of these and the user, we will know from where they perform these tests.
    You should also know that the speed test has its own server from where the file is downloaded. Being able to determine which the servers of this are will show the reliability of said test.
  4. If the speed test servers are far apart, the test connection speed will be very low. That is why these servers exist throughout the planet.

The procedure will be:

  1. Having selected the correct servers, what is measured is the latency (time it will take a file from the server to the user), and for this it sends pings to the server from our device, in order to know for sure how long it will take to answer. This time should be short, especially if it is about video games, video calls, or streaming movies.
  2. From there, the files are downloaded and then uploaded to the server. It is here where we will be able to see the needles that mark the speed, but the most important thing is the average speed that will later be thrown with the results.
  3. If there are more devices connected to the same network, this will influence the speed to be slower, since they are consuming the bandwidth of said connection to the server. This means that the speed will improve as there are fewer devices connected to the Wi-Fi network.
  4. It is also necessary to point out that the speed will not be the same if our computer is connected to a Wi-Fi network.
  5. If the PC in the background is performing other functions, such as downloading files or running a video game, the speed test will give a much lower result.


Tips to keep in mind when doing a speed test

In order for the speed test you perform on your computer to show a positive figure, you must take the following into account:
