7. Why is the operating system on the storage capacity is inconsistent with the
nominal value?
And computer hard drives, why the computer capacity is often smaller than the
nominal value of the capacity, which is caused by the transformation between different
units. We know that in the computer 1GB = 1024MB, hard drives and flash memory
manufacturers are usually translated in accordance with 1GB = 1000MB, converted
into G unit, the number of actually available MB is not diminished, which is part of
the normal.
Part of the local system embedded applications and games, system-related files and
curing applications need to occupy part of the flash memory, so users of the machine
can actually flash memory space than the nominal space is smaller, which is part of
the normal, and in order to prevent the destruction done to hide processing, users can
access and delete, and use the system disk, flash memory total capacity and nominal
capacity, ease of use .
