bandwidth
Definition
How much data can be transmitted in a time period over a communications channel, often expressed in kilobits per second (kbps).
Information
The difference between bandwidth and data transfer causes much confusion and is worth noting.
Bandwidth is a rate and data transfer is a total. For example, you might be a web hosting plan with 128 kbps of bandwidth for a maximum monthly data transfer of roughly 40 GB.
