What is bandwidth? How to calculate hosting bandwidth for your website

Bandwidth is a familiar term in information technology, and it matters a great deal in modern life. Ever waited hours for a video to download, or had your connection drop in the middle of important work? Those experiences all come down to bandwidth. So what is bandwidth, and why does it matter? Read on with MONA Media to learn more about bandwidth below.

What is bandwidth?

Network bandwidth can be pictured as the “road” data travels on across a network. Think of it as a water pipe: the wider the pipe, the more water flows through and the faster it flows. In the same way, the greater the bandwidth, the more data can be sent in the same amount of time.

For example, when you watch HD video, download a large file or play online games, you are using your bandwidth. If bandwidth is not enough, these activities become slow, choppy or even impossible.

One important point: bandwidth is not the same as network speed. Network speed measures the time a data packet needs to get from point A to point B. Bandwidth measures how much data can be sent in a given period. Both affect our online experience, but in different ways.

What is wide bandwidth?

Wide bandwidth (also called broadband) describes the ability to move data at high speed over a network connection. Think of it as a highway: the wider the road, the more cars can travel at once. In the same way, the wider the bandwidth, the more data can be sent in the same amount of time.

What is unlimited bandwidth?

Unlimited bandwidth means a type of network connection with no cap on the amount of data you can send or receive. You can use the internet freely to watch films, download files, play games and more without worrying about running out of data or losing speed.

Although it is called unlimited bandwidth, most providers actually have terms of use. For example, they may slow your speed if you use too much bandwidth in a short time, or apply fair-use policies so that all customers get the best service.

What is a bandwidth limit?

A bandwidth limit is a “wall” on how much data you can transfer over a network in a given period. Imagine downloading a large file: once you pass the limit, your download speed drops sharply or the transfer stops. The limit exists so that every user on the network gets stable, fair access.

Bandwidth limits are common in networking, and more specifically in web hosting services, Cloud VPS, and so on. Put simply, it is a “finish line” capping the maximum data you can transfer over a network in a given period.

How does bandwidth work?

Bandwidth is the amount of data a network connection can carry in a given period. Picture a road: the wider it is, the more cars can travel at once. In the same way, the greater the bandwidth, the more data can be sent in the same second.

Bandwidth works on a proportional principle: the larger the bandwidth,, the more data can be carried. That means a line with a bandwidth of 1Gbps (gigabits per second) can carry 10 times as much data as a 100Mbps line.

However, how much data can be carried depends not just on the bandwidth of a single link but on the whole path. Imagine a water pipeline: if one section is too narrow, no matter how wide the rest is, the flow is limited by the narrowest section. Likewise, in a computer network, if one link on the path has low bandwidth, it becomes a “bottleneck” and limits the speed of the entire path.

Common types of bandwidth 

Depending on how it is used and its technical characteristics, bandwidth falls into several types. Here are some common ones:

By scope of use

By scope, there is domestic bandwidth and international bandwidth. Domestic bandwidth carries data and traffic within a country. International bandwidth carries data across borders between countries. That is why, when an international cable breaks, connection speed drops badly.

By usage volume

Bandwidth is also divided by traffic demand. Plans with committed bandwidth guarantee a set access speed, and going over the connected and accessed volume costs extra. Shared bandwidth plans come next, used to share capacity among many server. The last plan is dedicated bandwidth, where you pay for what you use.

Does bandwidth affect your website and SEO?

Bandwidth is a core factor in how fast a website loads, and page speed is one of the top factors Google uses to rank websites in search results. How does bandwidth affect your website and SEO là gì (What is SEO)? Here is a quick look.

• Serving many users at once: High bandwidth lets a website serve many visitors at the same time without slowing down or crashing.
• Stable operation: Even at peak hours, the website keeps running stably without interruption.
• Up conversion rate: A fast-loading website raises conversion rate, especially for e-commerce and online stores.
• Higher engagement: Users have more time to interact with your content when pages load fast.
• Page speed: As mentioned above, page speed is one of Google's most important ranking factors. Large bandwidth improves page speed, which in turn lifts your website's ranking.
• A high drops: Slow pages make users leave easily. High bandwidth reduces this.
• User experience: Slow pages hurt the user experience, which affects customer satisfaction and the chance of conversion.
• Load capacity: For websites with heavy traffic, low bandwidth can lead to overload, making the website impossible to reach.

How to estimate hosting bandwidth quickly

To keep your website running stably and meeting visitor demand, estimating bandwidth accurately is essential. Here is a formula for estimating hosting bandwidth that you can use:

Estimated bandwidth = average monthly visits x average page size x average pages viewed per visit

Where:

• Average monthly visits: Check Google Analytics to get the most accurate figure.
• Average page size: Use a page size checker to calculate it.
• Average pages viewed per visit: Based on data from Google Analytics or other analytics tools.

Suppose you run a built an e-commerce website fashion website. You expect about 50,000 visits per month, an average page size of 2MB, and 8 pages viewed per visitor on average.

• Estimated bandwidth: 50,000 x 2MB x 8 = 800,000 MB, or 800GB
• Buffer: choose a hosting plan with at least 1TB of bandwidth so the website runs stably and has room to grow.

To keep the website stable in the future, reserve some extra bandwidth to cover its growth.

One more thing: besides calculating by hand, you can use online bandwidth estimators for quicker and more accurate results. Also consult your hosting provider for a plan that fits your needs.

Bandwidth units

Bandwidth is the maximum amount of data that can be sent in a given unit of time over a transmission channel. These are the common bandwidth units:

• Bits per second (bps): This is the most basic unit, showing how many bits of data can be sent in one second.
• Kilobits per second (kbps): 1 kbps equals 1,000 bps.
• Megabits per second (Mbps): 1 Mbps equals 1,000 kbps. This is a very common unit for home internet speed.
• Gigabits per second (Gbps): 1 Gbps equals 1,000 Mbps. It is usually used to measure high-end network connections, such as business networks and data centers.
• Terabits per second (Tbps): 1 Tbps equals 1,000 Gbps. This is a very large unit, used in high-speed data communication systems.

How much hosting bandwidth does a website need?

Choosing the right hosting bandwidth for a website is an important decision that directly affects its performance and load capacity. Here is what you need to work out when choosing a suitable hosting plan:

• Expected traffic: Estimate the average number of visitors per month, especially in peak periods.
• Average page size: Measure the average size of your web pages, including images, video and other elements.
• Content type: Is the website mostly text, images, video or web applications? Content heavy on images and video uses more bandwidth.
• User interaction: Does the website have many interactive features, such as live chat, file downloads or video streaming?

How you choose hosting bandwidth has a big effect on SEO results. Consider how much space your posts, images and videos will need. SEO companies can advise on this too. During web design, buying a domain, hosting with MONA, our expert team will go through these points with you in more detail.

Related bandwidth topics

This is only the basics of what bandwidth is and how to measure hosting bandwidth accurately. There are many other concepts and specialist topics around bandwidth that may interest you. Below are 5 bandwidth-related issues you may need to know.

Bandwidth throttling and how to fix it

Bandwidth throttling is a fairly common problem for internet users. It happens when the internet service provider (ISP) deliberately slows your connection. If you suspect throttling, use tools to check and find a way to deal with it. The most accurate check is at the end of the month on your hosting.

To fix and prevent throttling, you can try the following:

• Contact your provider: Call your network provider to report the problem and ask them to check the line.
• Using VPN: A VPN can anonymize and encrypt your data, helping you avoid throttling. Choose a reputable, fast VPN service.
• Optimize your devices: Close unneeded apps, update software and use caching to reduce the load on the network.
• Manage bandwidth: Use bandwidth management tools to control and prioritize network traffic.
• Upgrade your plan: If you need more bandwidth, consider upgrading to a higher plan.

Latency and how to fix it

Latency is the delay between sending a request and receiving a response from the server. The lower the latency, the smoother the connection, especially for activities that need fast response times such as online gaming, video calls or online meetings.

Latency directly affects network transfer speed. Besides network incidents, it can also come from faulty modems, a virus on your machine or users overloading the network. For this, all you can do is find the exact cause and fix it. A broken fiber-optic cable has to wait for the carrier to repair it. 

To fix and prevent latency, you can apply these solutions:

• Choose the right service provider: Pick network or cloud providers with stable lines and low latency to keep the connection quality high.
• Optimize network configuration: Check and adjust the settings of your network, router and other devices to reduce latency.
• Use the right protocol: Choose the transmission protocol that suits each type of application to optimize performance.
• Apply modern technology: Use technologies such as TCP acceleration, caching and load balancing to raise network performance.
• Optimize applications and content: Check and optimize the source code, images and files on your website to shorten page load time.
• Using Content Delivery Network (CDN): A CDN serves content from the server nearest to the user, cutting latency.

What is the difference between page speed and hosting bandwidth?

Internet speed and bandwidth are often used together, but they are not the same thing. Here is how the two differ, so you can understand them better:

• Bandwidth is often compared to the size of a water pipe. It is the maximum amount of data that can pass through a network connection in a given period. The larger the bandwidth, the more data is sent and the higher the potential connection speed. Bandwidth is usually measured in Mbps (megabits per second) or Gbps (gigabits per second).
• Internet speed refers to the actual speed at which data travels over that connection. It is like the speed of the water flowing through the pipe. Internet speed depends on many factors, including bandwidth, line quality, distance to the server and network devices.

Some figures shown on hosting plans

Here are a few things to note when choosing hosting bandwidth

• • Disk Space: Figures related to storage
  • Addon domain: an extra domain registered to run separately.
  • Parked domain: a secondary site for the main domain.
  • FTP (File Transfer Protocol): a protocol for transferring files (FTP client).
  • MSSQL or MySQL: the database of the website's hosting plan.
  • Hosting Controller or cPanel: software used to manage your domain website management, hosting. Examples include folder management, database, data backups, subdomains…

Tips for increasing your bandwidth

To increase bandwidth and improve website performance, you can apply the following:

• Upgrade your hosting plan: Invest in a plan with higher bandwidth to meet growing traffic.
• Optimize your website: Reduce page size by compressing images, optimizing code and bundling resources.
• Use caching: Speed up page loading by storing static versions of your pages.
• Improve server configuration: Make sure the server has enough resources to handle heavy traffic.
• Reduce the number of network requests: Optimize your website structure to lighten the load on the server.
• Use a CDN: Distribute content across many servers to speed up access and take load off the main server.

Common bandwidth problems and how to fix them

Here are some common bandwidth-related problems and how to fix them:

• Restricted bandwidth: A common problem is restricted bandwidth, where your internet provider caps your data transfer speed. To fix it, contact your provider to upgrade your plan, or consider switching to a provider that offers higher bandwidth at the same price.
• Unstable connection: If your connection is unstable, bandwidth may well be the cause. Check your network devices such as the modem and router and make sure they work properly. You can also reset them or contact your provider for support.
• Network overload: When many people use the network at the same time, bandwidth can be overloaded, reducing speed and connection performance. To fix this, use the network at quieter times, or add bandwidth by upgrading to a higher plan.
• Cable and network equipment problems: Damaged cables, faulty network devices or wrong settings can also cause poor bandwidth. It is best to check the cables, replace or repair them if needed, and make sure devices are set up with the correct configuration.
• Poorly optimized software: Some apps and programs on your computer can use too much bandwidth and slow the network. To fix this, check and close all unneeded applications, or set a bandwidth limit for each program.
