megabyte (MB)

The designation megabyte (MB) is generally used for determining the storage capacity of memories, primarily for memory chips. The mega is a prefix based on the decimal system: `10^6`, or 1 million.

However, since the byte refers to the exponentiation of the dual system, one million bytes correctly corresponds to a storage capacity of `2^20` bytes. This size is called mebibyte (MiB) in the National Institute of Standards and Technology ( NIST) system of units because the absolute value is 1,048, 576 bytes or 1,024x1,024 bytes, which is different from the absolute value of 1 million bytes.

Regardless of this, some standardization bodies such as the Storage Networking Industry Association( SNIA) prefer the specification in powers of ten for the storage capacity.
