Bandwidth – Short and Simple!
I was reading a favorite blog of mine, Nettuts+ and found this to be the simplest explanation for bandwidth. Thank you Andrew Burgess!
When looking for a web host, you’ll often see storage and bandwidth hand in hand. What is bandwidth? It’s the amount of data that your host will let you and your visitors upload and download (cumulatively) in a given month. Say your website is 1 megabyte of data and your monthly bandwidth is 10 MB. At the beginning of the month, you upload the entire site; now you’ve used up one MB of bandwidth. If a visitor to your site views every page, they will have downloaded 1MB of data. That means you can have up to 9 visitors in that month (assuming each views your whole site). After that, your web host will either not allow any more visitors, or (more likely) charge you extra per MB. Of course, your bandwidth is something you’ll want to keep an eye on, especially if you run a fairly popular site or do something media intensive (like host your own video, or high-res photos). Just like storage, some hosts offer “unlimited” bandwidth; again, if you think you’ll be in a grey area, find out the limits or choose a host that sets the bar where all can see it.
