The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.

It isn't an issue of advantages, it is an issue of compatibility with your computer. The 64 bit operating system can take full advantage of the capabilities of a 64 bit microprocessor, if your computer has a 64 bit microprocessor. However a 64 bit operating system will not run at all if your computer has an older 32 bit microprocessor; you will have to use a 32 bit operating system on that computer.

It is depended on how many bits the processor can process simultaneous... Means 8 bit microprocessor can process 8 bit of data simultaneously... & also it has 8 line data bus.. to transfer the data between memory & IO devices.... In same way for 64 bit..
It can process 8 bit data simultaneously ... In pcs we use 64 k bit which means it can process 64 bits of data at a time :)
A 64 bit microprocessor such as Intel 64. These types of microprocessors are compatible with all major popular Operating Systems.
Intel invented the 32 and 64 bit microprocessor which are in all modern computers
8086 is a 16bit processor.
Some microprocessor trends include the ability of microprocessors to execute one billion instructions per second. It also includes having 64-bit ALUs.

32 bit applications will work on 64-bit but they will not run as efficient as 64-bit application. the reason for this is the 64-bit uses the memory better than a 32-bit. this is why a 32-bit can only use up to 3 gigs of ram and a 64-bit can use 16 gigs +
