what is the difference between 32 bit O.S n 64 bit O.S?

Answer Posted / bose_85

The difference is the amount of information the PC’s processor
can handle at any precise moment. While a computer designed
for a 64-bit operating system has vastly more potential
computing power, it requires fundamental changes to the way
its software is designed.
There are also some significant mathematical limits to the two
different types of processor. A 32-bit processor can only work
with a maximum of 4GB of memory, and this is usually limited
to 2GB for any one program. A 64-bit processor could
theoretically work with 17 billion GB of memory.
