Transfer capability

Transfer capacity is the maximum amount of data that your Internet access you can transfer each month (from the Internet to your computer), upstream (from your computer to the Internet) or together (in both directions) . This capacity is measured in billions of bytes (GB).

Gigabyte (GB)
