A bit (origin: binary digit "binary number" or "dual number") is the smallest possible electronic information unit in data processing and computer science. A bit knows only two values: Off / On, 0/1 and No / Yes. Any information can be displayed by stringing together a fixed length of bits.
Bit to byte is converted using the conversion number 8. All other units (e.g. bytes to kilobytes) are calculated using the conversion number 1024.
