Well, answer this: Let's say you have a webpage and expect 100 visitors a day. And each visitor downloaded a 1MB file from your site. What would be the bandwidth per month for this scenario? 100 * 1MB = 100 MB / day 1 month = 31 days = 31 * 100 MB = 3100 MB = 3.1 GB / month Not too bad, but if you get 200 visitors/day, it doubles to 6.2 GB / month, and that's just the download. You also have to add in all those jpgs and gifs, text, etc...
