1000 by manufactures. 1024 as seen by computers
A gigabyte (often abbreviated as GB) is commonly understood to be 1,073,741,824 bytes, which is 2^30 bytes in binary computing. However, in the context of storage devices and some definitions, it may also be considered as 1,000,000,000 bytes (10^9) in decimal. The term "gaga byte" seems to be a typographical error or a play on words, as there is no standard unit by that name in computing.
I believe you meant difference between a bit and a byte. A byte is 8 bits.
There are two nibbles in a byte.
Eight bits are in one byte
1024 amos byte = 1 pectrol byte
Byte, since there are 8 bits in every byte
Yotto Byte
they are amounts of unit describing computer storage
8 bits are a byte
