# memory in pen drive

The actual data that can be stored in a pen drive is actually less than that specified,as in if a pen drive is of 2gb ,it has the storage capacity of 1.90gb.
For what is the remaining space used?
Is it for FAT?Can anyone please specify the exact reason..

Lets do some calculations,

We all know that,
1 GB = 1024 MB ----------(1)

But the manufacturers round it off to 1 GB = 1000 MB
So, 2 GB = 2000 MB (according to them).

Our operating system calculates memory according to (1).
So, 2000 MB divided by 1024 MB = 1.95 GB

Thus the OS shows us 1.95 GB.

Hope you get it now.

No, the actual memory isn't 2.0 GB. Its just a rounded off value that manufacturers print.
