How to protect children on the internet? Try our tips
Children's safety on the internet is largely the responsibility of parents. Therefore, we have prepared a comprehensive guide to protecting children online. You'll learn how to communicate openly with them about risks, set boundaries, and protect their privacy.
Astronomers' nightmare: Starlink satellites could blind radio telescopes
A new study has revealed a worrying fact: Starlink satellites from SpaceX, intended to provide internet, produce disruptive radio emissions that threaten space observations by radio telescopes. Emissions from the second generation of Starlinks are up to 30 times stronger than the previous generation, posing a serious problem for astronomers.
Outputs of this test
- download speed test - the speed at which data are downloaded from the testing server
- upload - the speed at which data are uploaded to the testing server
- ping - the time needed to send and receive a small amount of data
Connection speed under a magnifying glass
The results of the test show you a series of key values that allow you to evaluate your connection and decide, for example, whether to choose a different rate or another provider. The main values include:
Downloading
Downloading shows the download speed of data to your device, expressed in megabits per second (Mbits). A higher value is better because the faster the download, the less time you wait to load a web page or to download an email attachment. A home Internet connection is usually asymmetrical, which means that the data transfer speed to the user is higher than the upload speed.
Uploading
Another basic value revealed by the test results is upload. Upload shows how fast you can upload data to the internet with your connection, also measured in Mbit/s. As with downloading, a higher number is better. A quick upload is important for backing up to the cloud or for streaming. The higher the value, the faster you can upload data from your device to the internet.
Ping
Ping measures the time it takes for data to be sent from a host to a destination computer and back again. It is measured in milliseconds (ms). As opposed to downloading and uploading, with ping, the lower the value, the better. This value is especially important for online game players who need a quick response from the server when playing, so that their action in a game is not delayed. A relatively fast ping is less than 40 ms. Anything within the range of 0 to 10 ms is considered a very good result.
Jitter
Jitter expresses the fluctuations of the ping value and, therefore, the stability of the connection. The result (in milliseconds) should be as low as possible. The higher the jitter value displayed in the test, the worse your internet connection stability is.
The detailed results of the speed test show the amount of data in megabytes (MB) that you can theoretically download and upload during a given period of time. Thus, you can easily find out if the data volumes and speed are adequate. This is highly practical. The owners of blogs and websites have the option of inserting a free connection speed test directly on their websites through the embedding code.
Numbers that do not lie
You pay your internet provider for an internet connection which must meet certain technical parameters within the selected rate. These include not only the download speed, but also the speed of data uploading, along with the latency or response (ping) time.
In practice, however, these values can vary considerably from those advertised. This could be a long-term issue or perhaps only a short-term complication due to a technical problem or an aggregation (sharing the capacity of an internet link among multiple users). The speed test will help you to discover these differences and show you the actual speed of your connection. This can be done in less than a minute and without any complicated setup.

Is AI smarter than humans? OpenAI o1 excels in science, programming, and mathematics
OpenAI has introduced a new series of AI models called o1, which promise a revolution in complex thinking and problem-solving. The o1 models excel in fields such as science, programming, and mathematics, achieving results comparable to those of doctoral students. OpenAI has also focused on safety and developed a new training approach to prevent AI misuse.
The future of the internet: Are we heading towards a world like Blade Runner?
Think of the breathtaking vision of the future from the movie Blade Runner – holographic ads, cyberspace, and ubiquitous networks. Can this fiction become reality? Find out what we can expect from the internet of the future and how the boundaries between reality and the virtual world will blur.
PoE – the possibility of power over a network cable
Network ethernet cables are typically used for data transmission. However, the IEEE 802.3af and 802.3at standards also define the function of power over a network cable. This way, you can power small network devices without the need for an additional power cable. Let's focus on the advantages and disadvantages of PoE (Power over Ethernet) and its specifics.
How do Internet speed measurements work?
From the user’s perspective, everything is simple. In your web browser, click on the measurement button and wait. Before starting the speed test, it is important to close all tasks, applications, and devices that connect to the internet. The results would be affected by open tasks. You would not obtain the desired information, or the conclusions would not have the required notification value.
The technical solution and the background of the speed test itself are complex, but to explain it briefly, the test simulates a situation in which you download or upload data. The measured values are calculated depending on the speed of these transmissions. You can test the speed of up to 30 test servers located in geographically different locations. What will you discover?
Check your connection regularly
In the case of an internet connection, it is definitely not true that what was valid yesterday must still be valid today. Do not hesitate to repeat the speed test from time to time, or whenever you have connection speed problems.
The speed test will immediately give you an answer so you can decide your next step. However, these days it makes no sense to waste time with a slow internet connection.
