The speed of the MOBI data network is measured in Kilobits  per second (kbps). However, the amount of data transmitted over the MOBI data network is measured in Kilobytes (KB), Megabytes (MB) or Gigabytes (GB).

Bit

A unit of information that respresent a single character.

Byte

A unit of information composed of 8 bits.

Kilobyte

1000 bytes (measuring the number of kilobytes tells you the size of a file and/or the amount of data you have used).

Megabyte

1000 Kilobytes (measuring the number of megabytes tells you the size of a file and/or the amount of data you have used).

Gigabyte

1000 Megabytes (measuring the number of gigabytes tells you the amount of data you have used).
