Capacity of hard-disk is always expressed in GBs (Giga-Bytes). Since it is the heart of computer, its capacity broadly indicates computer's memory capacity. My system is not too high in GB. It is only 40 GBs. Thanks.
hard disk is default as 1gb=1000mb ,1mb=1000kb,1kb =1000byte
so 80gb=8x10^10byte,isnot 80gb =80x1024x1024x1024byte.
our harddisk used format is usually have about 76gb
this is the capacity in bytes of my computer:85899345920.
i have 80 gb hard disk and this is the value in bytes.
u can check it out.
i have calculated it .
have a nice day.
