This question already has an answer here:
I have noticed this strange thing.All things related to Computers come in values which are powers of $2$.For eg. Rams come in $2,4,8$ or $16$ GB,pendrives and memory cards also come in similar values.Computers are $8,16$ or $32$ or $64$ bit values.
Everything remarkably a power of $2$.Why is everything $2^n$?
Why?Thanks for any help!!
