[Solved]What is the difference between 32 bit Os n 64 Bit OS

i Always had the doubt of whether if i put a 64 bit OS instead of my 32 bit os , whether my comp ll become faster ………………..exactly what difference ll it make , can some one plz clear my doubt in simple english(I am using Win 7 Ultimate 32 bit )
Answer #1
The only difference between any 32 bit and 64 bit OS is the support for more RAM (over ~3.5GB in 64 bit OS’s).
OR
It has to do with the instruction sets, but that is another thing….all applications and softwares support x32, but many doesn’t support x64….you can opt for x64 if you have a RAM greater than 4GB….

x86 and x64 are all actually about the microprocessor.
x86 family of processors are 32-bit processors (though the first in the family, 8086, was a 16-bit processor) while X64 are 64-bit processors.
The term 32-bit and 64-bit comes from a particular feature of the microprocessor called the register. It is a tiny and temporary memory or storage inside the processor. A 32-bit processor has 32-bit registers or it can process 32-bits at one go where as a 64-bit one can process 64-bits at one go. So a 64-bit processor can process larger volumes of data than 32-bit processors.
x86 and x64 operating systems are those which can use the processor efficiently. An x86 OS on a 64-bit processor is going to use only 32-bits of the register, so that�s 32-bits of the register unused. To get the best out of your processor, use the OS which matches your processor.
And about the memory limitation. Each memory has an address. These are binary addresses given out by the processor. So an x86 processor can handle only 32-bit length addresses. So the maximum memory size it can address is 2^32 = 4GB (including cached memory and all those extra memory location, so a 4GB RAM won�t be addressed as a 4GB one (You might get something around 3). Whereas x64 processors can address up to 2^64 memory locations and that is about 16TBs (theoretically, anyway).
So using a 64 bit operating system will enable you to use your PC hardware to the maximum and there will be some minor noticeable increase in speed as the processor can now handle more data (64 bits in one go) than previously (which was limited to 32 bits).
Hope this helps. Cheers!
