Thanks. We'll let you know when a new response is added.

Computers run on the binary system which is the no. to the power of 2.

for eg : if we want to make a memory card of 4 GB
1 GB= 2^30
2 GB=2*1 GB
4 GB=2*2GB
8 GB=2*4 GB…..SO ON
but for eg, if u want to make a 7 GB memory card 
7 GB=4 GB+2 GB+1 GB
developing 8 GB is much cheaper and less complex then developing 7 GB memory card same is with 3 GB and 11 GB .

    I might suggest that you pick up a book on binary language and learn on how it is configured, then you would have your answer. Also, try to Google it, you would be surprise how what is out there.

    Could not improve on your answer..

    The power of two allows everything to be split evenly. 
    You cannot split 3 evenly in the computer world
