When I check C:\ Drive properties, it shows the total capacity as 111
GB when it is 120 GB, why this difference? Thanks for your help.
Because it's really 111GB, not 120GB.
All hard drive manufacturers define 1GB as 1,000,000,000 bytes, while the
rest of the computer world, including Windows, defines it as 2 to the 30th
power (1,073,741,824) bytes. So a 120 billion byte drive is actually a
little under 112GB.
Some people point out that the official international standard defines the
"G" of GB as one billion, not 1,073,741,824. Correct though they are, using
the binary value of GB is so well established in the computer world that I
consider using the decimal value of a billion to be deceptive marketing.
