  Topics List of device bandwidths Topic Home

This is a list of device bandwidths: the net bit rate (or, more informally, digital bandwidth) of some computer devices employing methods of data transport is quantified in units of kilobits per second (kbit/s), megabits per second (Mbit/s), or gigabits per second (Gbit/s) as appropriate. They are grouped by similar functionality, and then listed in order from lowest bandwidth to highest.

In addition, a common scale is used to better convey the magnitude of change to a non-technical person (for example: a 1.2 kbit/s telephone modem

DSL or xDSL, is a family of technologies that provides digital data transmission over the wires of a local access network.

Note: All of the figures listed here use metric (base-10) abbreviations:
  • 1 kbit = 1,000 bits
  • 1 kB = 1,000 bytes
  • 1 MB = 1,000,000 bytes
  • 1 GB = 1,000,000,000 bytes
  • 1 TB = 1,000,000,000,000 bytes
and so on.
