Test Tốc Độ Mạng Lan

An internet tốc độ 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 mạng internet connection, namely ping (latency), download speed, và 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 lớn these, we first want to lớn discuss how to lớn perform each test.

How to test download speed?

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

How to demo upload speed?

Upload speed is tested by reversing the sequence of the tải về analysis. Again multiple connections are opened khổng lồ the thử nghiệm server. Instead of downloading a file, a large file of random data is created on your device and pushed through all connections lớn the server. Pushing the data lớn 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 mạng internet speed for uploading data.

How to kiểm tra ping?

During the ping test, the device sends a small data package over the network lớn the kiểm tra server on the internet. When the vps receives this package, it will send it back to the device, completing the roundtrip. The time it takes the data package to lớn 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 congthuong.net. But you should take one crucial aspect into tài khoản 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 thiết bị di động devices, you should tải về our ios or android app, respectively. This is especially important when running a WiFi tốc độ test. Because browsers on điện thoại devices have poor performance, we suggest using a mobile app written in native code khổng lồ ensure the most accurate speed chạy thử results.

What is tải về speed?

The tốc độ 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, tải về speed is denoted in Megabits per second (Mbps or Mb/s), although other forms lượt thích 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 tốc độ characterizes the amount of data your device can send khổng lồ 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 lớn the time it takes that signal lớn travel to lớn 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 hệ thống 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?

How fast is your internet?

It"s important khổng lồ 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 lớn what you want to lớn 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 lớn Youtube will be primarily constrained by your upload bandwidth.
