Why isn't the entire space of a pen drive and memory card available for storage?
Whenever you buy a new pen drive and plug it in always you would have noticed that you won't get the full capacity as mentioned in the box. Have you wondered why?
Basically, what manufacturers do is they have a standardized value of representing the storage space in terms of 10^3 i.e (1Gb = 1000Mb). But on the other hand, in our computer's 1Gb equals to 1024Mb. So a 4Gb pendrive will have 4000Mb of storage in it. But when you plug it into the computer what it does is it divides 4000/1024 and gives you the equivalent amount of Gb which is less than the specified.
