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. you 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 it in one word. how many bits of data are transmitted per second? this term is called bandwidth, ie 8Mbps/second (8Mbps). which can transfer 1 million bits per second here.

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 rates. which tests your internet connection speed in normal language. When you start a speed test on a speed test website. you are given a result by measuring the data transmission rate from your computer to the server computer and 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 can download files from Bangladesh or Asian servers as well. you can not download files from the server in the USA 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 high (186,000 miles/second). but even then it has a limitation. which means it has the ability to cross only 186,000 miles per second. so if the server is away from your location. it will definitely make a difference in transfer speed.

Generally, download speed is better than upload speed. but why? Because most Internet users download files from the server more. But uploading files to the server is much less. 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. Because when you download a file from the server. of course, the server is uploading the file to you.

You can check your average bandwidth using either SpeedTestNet or Fast.com SpeedTest sites. Many ISPs provide their own bandwidth tester. You can use them to get an idea of ​​your bandwidth speed. It is not possible to get the speed exactly because it has many factors that I have discussed above.

Bandwidth Vs water tube

To understand the bandwidth term, you can compare it to a tap of water or a tap. If the transfer rate goes up. the water will start flowing faster at a given time. A water pipe must have a limit. how much water can you allow to flow over a period of time?

Suppose you are downloading a movie with a broadband connection. streaming video from that connection. gaming multiplayer. calling VoIP – the more you spend on bandwidth. the slower your connection will be. Now let’s take the example of a water tube. you have the main water pipe in your house that has the ability to transfer a certain amount of water at certain times. Now if you leave the kitchen taps. bathroom taps. garden taps together. the water speed will be lower on all the taps. Because the source will provide all tubes with speed based on the water pressure. So you understand clearly about bandwidth speed?

This time there is another term. especially for the mobile internet. depending on how much money you are paying you to get the bandwidth amount fixed. In this case you have to think of two things: first. you can transfer data only from that network to a certain amount of data (1GB or 1GB or whatever amount you have paid for data transfer). then you have the bandwidth-rate factor right there. every second.

How many bits of data can you transfer (10 million bits/second)? The bandwidth rate is calculated as megabits/second (Mb/s). and the file size is calculated as megabits (MB). This is why they sell plans like 1Mbps / sec (1Mbps) when buying the internet from ISP. but you only get~120kb/s (~128 KB/s) speed when downloading files. Why bits and bytes are two separate measurements. 1 byte contains 8 bits. which means your rated connection will be 8 times smaller in megabytes.

Megabits / second Vs Megabits / second

Although the bandwidth rate is normally determined by bits/second. you should know that it is possible to rate bandwidth rate by any unit such as kilobytes/second (Kb/s). kilobyte /second (KB/s). megabits/second (Mb/s). megabits/second (MB/s). gigabits/second (Gb/s). gigabits/second (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 you get 8÷8=1 megabits/second (1 MB/s) speed in MB.

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. If you still have questions. be sure to comment below!
