Bit (BIT) (binary digits): stores a bit of binary, that is, 0 or 1, the smallest storage unit.
Byte: eight binary bits are one byte (B), the most common unit.
Generally, the computer storage unit is represented by B, kb, MB, GB, TB, Pb, EB, ZB, Yb, and BB. The relationship between them is:
1kb (kilobyte kilobytes) = 1024b,
1 MB (megabyte MB for short) = 1024kb,
1 GB (gigabyte, also known as "Gigabit") = 1024 MB,
1 Tb (trillionbyte trillion bytes too byte) = 1024 GB, of which 1024 = 2 ^ 10 (10 power of 2 ),
1 Pb (petabyte kilobytes of bytes) = 1024 TB,
1eb (exabyte) = Pb,
1zb (zettabyte 100,000) = 1024 EB,
1yb (jottabyte 0.1 billion) = 1024 ZB,
1bb (brontobyte 100 billion million bytes) = 1024 Yb.
Note: "MB" is a unit of millions.
