Example – the audio file has a band width of 128 kilobits per second.
Bit (binary digit)
Measurement unit for data quantities. Whereby 1 bit is the smallest imaginable data quantity
which, for example, can be portrayed as a binary digit. Larger data quantities are always
whole-number multiples of 1 bit.
Bit rate
The band width which is required for the transport of contents.
Byte
A group of 8 bits. In order to avoid the usage of very large figure levels groups are defined in
bytes.
Kilobyte (kB) – 1,024 Byte
Megabyte (MB) – 1,024 Kilobyte
Gigabyte (GB) – 1,024 Megabyte
Codec
