- A bit is the shortest storage unit in computers which charts given below.
Bit = 0 or 1 single binary digit

1 Byte         = 8 Bits

1 Kilobyte(KB) = 1024 Bytes

1 Megabyte(MB) = 1024 Kilobytes

1 Gigabyte(GB) = 1024 Megabytes

1 Terabyte(TB) = 1024 Gigabytes

1 Petabyte(PB) = 1024 Terabytes

1 Exabyte (Eb) = 1024 Petabytes
