Computer data storage Unit with Comparison their values

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:

 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
