Data transfer, or bandwidth, is the total amount of information downloaded from your web site. Whenever a visitor comes to your site, our web servers send data to your visitor's computer. This data may include web pages, images, videos, sound files, software programs, or compressed files — anything on your site that can be viewed or downloaded.

The more visitors you have, and the more complex your web site, the more data transfer you'll need — which is why our Yahoo! Web Hosting plan includes unlimited data transfer. Learn more about Yahoo! Web Hosting.
