Understanding Web Hosting Bandwidth

By Matt Hedges


"Bandwidth" is a title that you may have heard many web hosts, including your own, discussing from time to time. A simple definition of this term is that is how much data is passed over an internet connection from one set to another. Bandwidth is one of the most important services that a web host can provide and is usually measured in how bits are sent each second. The amount of data being used on a website varies depending on what the the website is being used for. Sites where there is a lot of interaction and communication will take up a bigger bandwidth and this means sites like forums or blogs take up more bandwidth than a more common website. These sites offer far more interaction with the opportunity to load up content and add debate or opinions which is why they take up more bandwidth. These websites will have a greater amount of traffic in comparison to standard websites provided by firms which is another reason why in comparison, the amount of bandwidth that is used by communication or network sites will be much higher.

Knowing how to calculate bandwidth is important and easy. Take the size of your website to be 10 KB and that twenty people visit your site each day. This would mean your bandwidth usage could be calculated 10 x 20 bites for a day. Multiplying this figure by the amount of days in a month would give you your monthly bandwidth usage. It can be handy to know the other measurements as sometimes bandwidth is listed in bytes.

Many people get confused about how to translate the sizes but an easy way to remember it is that one byte is the equivalent of eight bits. The next step up is 1 kilobyte and this is the equivalent of 1024 bytes.

Another thing that can cause an ineffectual use of bandwidth is a vast number of pictures or a lot of user comments or remarks. It also makes sense that a person who has heavy usage on the internet including products that have a large size will invariably use a huge amount of bandwidth. This places a huge deal of importance on getting the right website from your web provider. The greater amount of visual, audio and graphical that is on a website, the greater the need for bandwidth will become. It is not always possible for a website provider to live up to the promises they make, so it is important to research them properly. As in all walks of life, having a provider who can meet all your needs is an important aspect when choosing your website host.

Determine the amount of bandwidth you need

When you are considering the amount of bandwidth that your site will require, there are many things to consider. There are many influences on the answer that is best for you and particular attention must be attributed to mathematic and technical issues. The available bandwidth will limit the amount of items you can offer on your website so for current and future projects, consideration has to be made. Given that it is likely you will want to update your website over time, it is advisable to leave some bandwidth in store to allow for progression. Allowing yourself the opportunity to contemplate how much bandwidth is needed for your site can allow you to make the best decision possible. A good way to get the best advice is to ask your web provider for advice about what would be the best product for you. The simplest way to determine the amount of bandwidth you need to use is on a monthly basis and this is why the majority of providers offer measurements in this manner. A way to measure bandwidth can be seen as:

The number of days per month times times the number of pages viewed times the number of visitors who use your site daily times the size of your page.

If you would like to offer a range of flexibility regarding bandwidth usage, the following calculation may be preferable:

[(Visitors per day x number of pages looked at x size of the page) added to (the size of downloads per day x the size of the file downloaded) times the maximum number of days in a month (31) times by a variable factor.

Note: These calculations have been created to work with the average figures for each element.

How traffic and bandwidth are linked:

Bandwidth and traffic are closely interlinked with each other. Visitors can experience best the bandwidth as they are the people who carry out various activities with the websites. If a visitor wants to download an MP3 files from a website into the computer, then 4MB traffic is created between the website and the user's computer. If the user is having a fast internet connection then the file won't take much time to get downloaded and hence the bandwidth consumed in the process would be low. The reverse happens if the internet connectivity is poor. Traffic is measured by the number of bits that are transferred on network connections.

Learn how to reduce the amount of bandwidth that you use.

We all dread bills and an unexpected bill can really cause panic and problems to a person. If you exceed your bandwidth amount, your provider is well within their rights to charge you for this as well as send you a reminder to keep your usage down. This may obviously cause you problems and you could be wondering how you can fix this problem.

Yours website has several files, each of these files have respective sizes of their own. Each of these files, when used by the visitors, consumes some of the website bandwidth. You have control on the bandwidth usage of your website and can increase or decrease these according to the requirements. Another easy way to cut down bandwidth expenses is to prevent the use of too many files, graphics, images and downloadable file son your website. These files themselves are heavy and when downloaded by multiple users, can consume lots of bandwidth thus increasing cost. Suppose there is a large image in the webpage that is downloaded each time a visitor views the website. Then also the same thing happens and unnecessary bandwidth expenditure takes place. If removing the web page images is not possible, then try to decrease its size and you can seen the dramatic change in the bill, next time, when the web hosting company hand it over to you. Cascading Style Sheets also help you to save bandwidth as they reduce HTML file sizes considerably.

Some bandwidth tips:

* Be able to have a rough estimate of the amount of visitors that access your site or may be likely to access your site at a later date. You can see why it can be of use to have a projection for monthly usage.

* There are options to buy un-metered bandwidth hosting. In such a plan you are charged higher than nay normal shared or dedicated hosting plan and in return the usage will be unlimited. The host won't monitor the bandwidth rating which is reflected on the left hand side of the control panel.

* When altering your website, ensure you make a note of the changes to allow your estimates to be up to date and more accurate.

* If you can, keep the number of visitors comments to a minimum. You may wish to allow only pre-approved or carefully selected comments onto your site.

* Be sure to communicate regularly with your web provider and seek their advice on how best to maintain or improve your website. Not every change will lead to a rise in the amount of bandwidth your site uses but there can be positive impacts as well. By removing any files that are no longer deemed necessary can free up bandwidth to be used for other purposes.

* Rather than hosting things like Java Script within your site, try having them hosted with an external agent.

* Bandwidth can be eaten up by graphics with a large size so always ensure to load up graphics that have been reduced in size.

Last remarks:

It is your web host that can guide you bets on bandwidth. Selection of the right web host can matter if your want a proper guidance on web hosting services. The structure and the content of the WebPages would definitely determine the bandwidth expenses. But the effective guidance from the web hosts can equally help you on this regard. Bandwidth theft is a common practice in which the people use other sites images by simply linking them with another page. Such practices, without notice, can be punishable and should not be practices. So if you are a novice, and your website owner advises you on this then always try to avoid. Before discussing with the web host regarding bandwidth and always better to make a study and some research on bandwidth. Your website developers can also guide you extensively in informing about the techniques to save bandwidth.
