Bandwidth is a web hosting feature that shows the traffic of your or any specific website. This feature is so important that many web hosts use high bandwidth to attract clients.
Bandwidth, network bandwidth, data bandwidth, or digital bandwidth is a measure of available or consumed data communication resources expressed in bits/second or multiples of it (kilobits/s, megabits/s etc.).
In website hosting, the term “bandwidth” is often incorrectly used to describe the amount of data transferred to or from the website or server within a prescribed period of time, for example, bandwidth consumption accumulated over a month measured in gigabytes per month. The more accurate phrase used for this meaning of a maximum amount of data transfer each month or given period is monthly data transfer.
When creating a website you should be fully aware how to manage it. One of the most vital functions when creating a website is the disk space and monthly traffic for it. The more bandwidth you have the more traffic your website will be able to handle.
Basically, traffic means the transfer of data between your website and your computer and bandwidth means the speed of the connection between the two.
Bandwidth is always stated as a monthly limit in either MB or GB. This is the amount of actual data that can be transferred from the web server that holds your website, to the browser of the person who is looking at your website. If you go over the limit, then either you will have to be an extra fee or your website will not be available. The amount of bandwidth you use is obviously related to the amount of traffic (visitors) that you receive.
High bandwidth hosting is for website owners/operators who have high traffic and want to be able to maintain optimally. Not all high bandwidth hosting providers require contracts to be signed for their services. Some hosting providers will offer specials that include month to month services.

High bandwidth hosting is hosting packages tailored with very large monthly bandwidth allotting.
