"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.



To define bandwidth mathematically one can say that, if your website is of 10 KB and the total number of hits is 20 per day, then your bandwidth would be 10 x 20 bites and if you want a monthly report multiple it with 30. Bandwidth is sometimes measured in bytes also.

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.

Understand the amount of bandwidth that fits your requirements.

How would you known that what is the required bandwidth of your website? This question needs to be answered from technical and mathematical point of view. This would also determine the website content you are having and have projected to include in future. It is always better to keep some bandwidth in hand as it would allow you to develop the website and include new features later on. You should take out some time in determining the bandwidth required for your website. If required you can discuss the issue with your web hosts who can suggest you better on this. Almost every hosting company measures the bandwidth plan on a monthly basis and hence you can chart your requirements based n that only. Bandwidth is generally measured 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.

While if you allow people ample downloading options from your website your bandwidth would be measured as:

[(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: All these are measured based on average data.

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.

Handy hints for your bandwidth:

* Always keep an estimation of the number of visiting or can visit your page in future. A monthly estimation is always beneficial.

* Have you considered the option of purchasing bandwidth that is not metered? This type of plan may cost more but it comes with more freedom regarding the size of bandwidth available, which will be unlimited. You will also have freedom from your web host who will not be constantly monitoring your website usage.

* Be sure to keep a note of any alterations that are made to your website. Knowing the up to date size of your site will allow you to accurately forecast your bandwidth usage and bills.

* Try to cut down the inputs from any visitors on your sites. Allow only selected visitors to make comments on your website.

* 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.

* A better way to embed JavaScript may be to do it on an external site as opposed to having it placed on every page.

* Always upload resized images as heavy images consume bandwidth.

The final words:

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.
