What is bandwidth? How to measure? – Everything you need to know!



In today’s growing Internet world, “bandwidth” is a well-known term – although there are many technical explanations of this term, it is called bandwidth to measure how much data units will be transmitted over a period of time on the Internet.


Physical access to broadband is very important in getting an internet connection, but using many types of methods you can get an internet connection now.



Not only do you have to have an internet connection, but you also have to have a high bandwidth rate. A video will not load as fast as a high-bandwidth connection, and may not load immediately over a low-bandwidth connection.



 If you want to express in one word, how many bits of data is transmitted per second, this term is called bandwidth, ie 8Mbit / sec (8Mbps), here 8 million bits can be transferred per second.


Bandwidth measurement



Now the question is, how much bandwidth do you have? How to measure? Many would say, “This is a very simple task, only dialing a SIM-specific code tells you how much bandwidth there is, and unlimited bandwidth when using broadband”.



In fact, you are completely wrong – the amount of data displayed on your SIM data account is just a limit, that is, how much bandwidth you can spend.

But if you are told what your bandwidth is, then the bandwidth rate is definitely being asked.




There are many speed test websites for measuring bandwidth rate, which tests your internet connection speed in normal language. When you start a speed test on a speed test website, transmit data from your computer to the server computer and You are given a result by measuring the data transmission rate from the server to your computer.



But it is never possible to get a perfect result. You can get average results and get ideas from there.



Transferring data from a server connected to the Internet, depending on where the physical location of that server is, data transfer rate.



You cannot download files from an Asian server immediately, you cannot download files from a server in America or Europe.



Because according to the laws of physics, data can never travel faster than the speed of light.



Yes, the speed of light is very high (186000 miles/second), but even then it has a limitation, which means that it has the ability to cross only 186000 miles per second, so if the server is away from your location, there will definitely be a difference on the transfer speed.


Generally, download speed is better than upload speed, but why? Because most Internet users download files from a server, But uploading files to the server is much slower. So ISPs reduce the upload speed.



But the internet connection on the server, the upload speed is high, and this is why you get more download speed from the server



Megabits / second Vs Megabits / secondAlthough the bandwidth rate is naturally calculated by bit / second, you need to know thatBandwidth rate can be rated by any unit such as kilobytes / second (Kb / s), kilobytes / second (KB / s), megabits / second (Mb / s), megabits / second (MB / s), gigabits / second ( Gb / s), Gb / s (GB / s).


Your internet service provider can use any one term, but your speed testing service may use a different term, video website separate term, downloading software different term.



But if you have the right idea about these terms, then you should not worry about why different speeds appear in different places.



For example, 10 megabits / second (MB / s) and 10 megabits / second (Mb / s) but not one thing. Here’s a good look at megabytes (b lowercase) and megabytes (b uppercase), with the help of which you can easily calculate megabits and megabytes.

Since 8 bits is 1 byte so bytes, 8 times bigger than bits! If the operator sells 8 megabits/second (8 Mb / s) of bandwidth, that means in megabytes

You get 8/8 = 1 MB / s (1 MB / s) speed.





Especially for mobile internet, you are fixed by the amount of bandwidth you pay.


In this case, you have to think about two things: first, you can transfer data only from that network to a certain amount of data (1GB or 2GB or whatever amount you pay for data transfer),



Again you have the bandwidth-rate factor here, how many bits of data can you transfer (1 million bits/second) per second.



The bandwidth rate is calculated as megabits/second (Mb / s), and the file size is calculated as megabits (MB).



That’s why when selling the internet from ISPs they sell the plan as 1Mbit / sec (1Mbps), but when downloading the file you only get ~ 125 kb / s (~ 128 KB / s) speed. Why bits and bytes are two separate measurements.



There are 8 bits out of 1 byte, which means your rated connection will be 5 times smaller in megabytes.



Bandwidth rates depend on other factors, such as latency, data packet loss, the difference between the time a packet is received to another. Anyway, hopefully from this whole article, all the dilemmas about bandwidth have cleared your mind.
