Units of Digital Information

Computing and telecommunication systems use units of information to measure storage and communication capacity. Bit,Nibble and Byte are the fundamental digital data units. The larger units, multiples of bits and bytes, are further categorized as Binary and Decimal units.

Decimal units are defined by SI(International System of Units), use Metric prefixes such as kilo, mega etc. Decimal units are multiples of 1000. Binary units are comparatively newer, defined by IEC(International Electro technical Commission), prefixed with kibi, mebi etc. evaluated as multiples of 1024. You can find further details on each units below.

Digital Data Storage Measurement Units : Smallest to Largest

Bit (b) is the smallest unit to measure digital data, whereas Byte is commonly used as the smallest addressable unit of storage in many computer systems. A Nibble can be formed by grouping 4 bits, can have up to 16 values.

Basic Units
Bit (b) 0 or 1 (Basic Unit)	Nibble 1 Nibble = 4 Bits	Byte (B) 1 Byte = 8 Bits
