What is bandwidth? How is it measured? – All you need to know!
Bandwidth is a very familiar term in today’s world of the internet. Although there are some technical explanations for this term, the measure of how much data unit will be transmitted over a period of time in the case of the Internet is called bandwidth. Physical access to broadband is a very important issue in getting an internet connection, but you can now get an internet connection using many types of methods. Not only an internet connection but also a high bandwidth rate is required. In short, this term is called bandwidth for how many bits of data are transferred per second, for example – 8 megabit/second (8 Mbps), here 8 million bits can be transferred per second.
Bandwidth refers to the amount of data being transmitted over a network or modem connection. It is usually measured in “bits per second” or bps. This can be easily understood by comparing bandwidth with the movement of cars through a highway. Here the highway is the network and the car is the transmitted data. The wider the highway, the more cars can move together. That means more cars can reach their destination at once. The same rule applies to computer data. The more bandwidth the more data or information can be sent together in a given time.

Now the question is, how much bandwidth do you have? How to measure? Many will say, “This is a very simple task, just dialing the specific code of the SIM will tell you how much bandwidth you have, and if you use broadband, you will have unlimited bandwidth.” In fact, you are completely wrong. The amount of data displayed in your SIM data account is just a limit, which means you can consume a total amount of bandwidth. But if you are asked how much bandwidth you have, then of course the bandwidth rate is being asked.
There are many speed test websites to measure the bandwidth-rate, which test the speed of your internet connection. 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 the data transmission rate from the server to your computer. But it is never possible to get the right result. You can get average results and get ideas from there. The data transfer-rate also depends on which server is connecting to the Internet and where the data is being transferred. The faster you can download files from Indian or Asian servers, the faster you can download files from servers 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 a lot (186,000 miles/second), but it still has a limitation, meaning it can only exceed 186,000 miles per second, so if the server is away from your location, there must be a difference in transfer speed.
You can check your average bandwidth using Speedtest.net or Fast.com speed test sites. Many ISPs provide their own bandwidth tester, which you can use to get an idea of your bandwidth speed. It is not possible to get the exact speed, because there are many factors, which I discussed above.
Bandwidth Vs Water Tube
To understand the term bandwidth, you can compare it to a water tap. If the transfer rate increases then water will start flowing more quickly at a certain time. A water pipe must have a limit, how much water you can flow in a period of time.
Now suppose you have a broadband connection, you are downloading a movie, streaming video from that connection, playing multi-player gaming, making VoIP calls, so the more bandwidth you spend, the slower your connection will be. Let’s take the example of a water pipe, you have the main water pipe in your house that has the ability to transfer a certain amount of water at a certain time. Now if you leave the kitchen faucet, bathroom faucet, garden faucet together, the speed of water will decrease in all the faucets. Because the source will give speed to all the pipes based on the water pressure. So I hope you have a clear understanding of bandwidth speed.
Now there is another term, especially in the case of mobile internet, you are given a fixed amount of bandwidth according to how much money you are paying. In this case, you have to think of two things first, you can only transfer a certain amount of data from that network (1 GB or 2 GB or whatever you have paid to transfer data), then you have the bandwidth-rate factor, just every second How many bits of data you can transfer (10 million bits/second). Bandwidth rate is calculated as megabits/second (Mb / s), and the file size is calculated as megabytes (MB). That’s why when they buy internet from ISP, they sell the plan at 1 megabit/second (1Mbps), but when you download the file, you only get ~ 125 kilobytes / second (~ 128 KB / s) speed. Because bits and bytes are two different measurements. 1 byte has 8 bits, which means your rated connection will be 8 times smaller in megabytes.

The bandwidth rate depends on more factors, such as latency, data packet loss, and the time it takes to receive from one packet to another. Anyway, from this complete article I hope all the dilemmas about bandwidth have been cleared from your mind. If you still have any questions, be sure to let me know in the comments below!
