What is meant by bandwidth


Often when planning a network or website and choosing a web hosting service, you have to predict and allocate the amount of bandwidth you will need, and this is often not what we know. For that we must understand what is meant by bandwidth, then we can understand how much bandwidth we need.

What is Bandwidth?


In its basic definition, Bandwidth describes the level of traffic, and the amount of data that can be transferred between your site, users, and the Internet. But there is another opinion that says that bandwidth is the maximum amount of transfer that can be made at a certain time in the data exchange process.


Think of bandwidth like a water hose. Say you need to fill a 100 gallon tank. If your garden hose only discharges 5 gallons of water per minute, you will be waiting 20 minutes to fill the tank. But a large firehose releasing a gallon of water every second will fill the tank in less than two minutes. Bandwidth is like hose size. The bigger it is, the more data you can pull in any given time.


Bandwidth is measured in bits per second. Note that bits are different from bytes, a common measure of file size. One byte equals 8 bits, so 1 megabyte (MB) equals 8 megabits. If you have a 1 megabit per second connection, file 1MB will take eight seconds to download. On a 1 Mbps connection, an MP3 file, which is about 6MB in size, will take about 48 seconds to download. A 5 gigabyte movie, or 5,000MB, will take about 11 hours.


Bandwidth Types

Bandwidth itself actually has two types, namely analog and digital bandwidth. Analog Bandwidth is a frequency range measured in Hertz/Hz which can determine the amount of data or information that can be transmitted at a time. While Digital Bandwidth is the volume and amount of data that can be sent through a communication channel without distortion. Expressed in bps or bits per second).


Bandwidth Function


1. Data Delivery Media


When we connect the LAN connection and PC devices using a LAN cable. In this case the bandwidth will work as a connecting line or as a medium that connects the data transfer process.


2. Transfer Speed ​​Limiter


Bandwidth also works to limit the speed of data transfer. Usually this speed limitation is used by administrators to manage the network in order to avoid high traffic usage. For example, when a device is used to download or play videos with High Display (HD) resolution. It can make a lot of bandwidth wasted and can interfere with other users.


3. Limiting Data Transfer Speed


Bandwidth also has a function to limit the data that can be transferred or sent according to a certain unit of time. Usually this function is used by hosting administrators as well as by network administrators. For example, when you provide 2GB of bandwidth per month, without considering the access speed and the number of devices that use it, the maximum data that can be sent is 2Gb and cannot be more than that.


How Much Bandwidth Do We Need


The bandwidth you share among all the devices on your connection. How much you need depends on how you use the internet. If you have one person downloading games, another person playing movies, and another person using Instagram on their phone, you will need quite a bit of bandwidth.


Video streaming tends to take up a lot of bandwidth, so households running the stream may want to increase the speed. Netflix recommends a 3 Mbps connection for standard video quality and 5 Mbps for high video quality. Two HD video qualities will require about 10 Mbps, and so on.


Online games do not require a lot of bandwidth to play. However, downloading games or other large files takes up a lot of bandwidth. Frequent file sharers and downloaders may prefer higher speeds. If you use the internet only for general web browsing, sending email, and social media, you won't need more than 1 Mbps. But if you have multiple users on the same connection, you have to take the extra bandwidth into account.


What Determines Internet Speed?


On cellular type connections, the difference between 3G vs 4G networks can affect your speed, as can signal quality. Average 4G speed 8-12Mbps. Expect speeds of 1-4Mbps on 3G networks. Internet speed varies. It depends on factors such as:

Location = Close to your head office, tower, or satellite provider


Number of Network Users = User traffic affects Internet speed


Infrastructure Quality = Providers with a well-managed network will deliver the best results


Conclusion


So what is meant by bandwidth? Bandwidth is the maximum rate at which you can download data from the internet to your computer. The greater the bandwidth and the small data flow, the data traffic will be smoother, on the contrary if the bandwidth is small and the data flow is large, the data traffic will be slow or even stop.
