* typically excludes email.

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 buy bandwidth of 128 kbps for a maximum monthly data transfer of roughly 40 GB.

128 kbps = bits = bytes
per second 128,000 16,000
per minute 7,680,000 960,000
per hour 460,800,000 57,600,000
per day 11,059,200,000 1,382,400,000
per month 331,776,000,000 41,472,000,000
divide by one billion

~41 gigabytes/month

Note: many hosts use the terms bandwidth and data transfer interchangeably, referring to a monthly data allowance as bandwidth.
