Q. What is data storage unit in computer? Compare the storage unit as bit, nibble, byte, kilobyte, megabyte, gigabyte, terabyte, pitabyte, exabyte and so on.
Ans.
Storage unit is used to measurement of data. In other word the capacity of storage medium is measured in bytes.
There are various storage unit(smallest & biggest) available in the modern computer era. The smallest storage unit is bit. bit is also called binary digit(b) or simple "binary". Hence the value of bit is 0 or 1.
The following table shows the list of computer data storage unit as smallest to biggest:

The following table shows the list of computer data storage unit as smallest to biggest:
| S.No. | Decimal(~) | Storage Unit | Comparison |
| 1 | - | Bit (b) | - |
| 2 | Nibble | 4 bit = 1 Nibble | |
| 3 | - | Byte (B) | 8 bit = 1 Byte |
| 4 | 103 | Kilobyte (K) | 1024 Byte = 1 Kilobyte |
| 5 | 106 | Megabyte (M) | 1024 Kilobyte = 1 Megabyte |
| 6 | 109 | Gigabyte (G) | 1024 Megabyte = 1 Gigabyte |
| 7 | 1012 | Terabyte (T) | 1024 Gigabyte = 1 Terabyte |
| 8 | 1015 | Petabyte (P) | 1024 Terabyte = 1 Petabyte |
| 9 | 1018 | Exabyte (E) | 1024 Petabyte = 1 Exabyte |
| 10 | 1021 | Zetta (Z) | 1024 Exabyte = 1 Zettabyte |
| 11 | 1024 | Yottabyte (Y) | 1024 Zettabyte = 1 Yottabyte |
| 12 | 1027 | Xonabyte (X) | 1024 Yottabyte = 1 Xonabyte |
