What is the difference between 32 bit and 64 bit OS?

the term 62 bit and 32 bit refers to the way in which the processors(cpu) handle information.the 62 bit version can handle large amount of memory 9RAM) than the 32 bit version happy lotting

Hi there keval, these OS's are built to run in two processor variations 32 & 64 bit,and their difference is in the amount instruction that it can handle at one time. You are familiar with binary,0,1.each can be called bit.so 32-bit processor can handle 32..0's or 1"s or its combination.likewise 64-bit proc --64.64-bit has more computing power. These processor has RAM limits too a 32 bit can handle only up to 4GB(2^32=4,294,967,296 ?4GB) a 64 can handle 17 billion GB(2^64=18,446,744,073,709,551,616) so the memory limitation is the main reason for the development of new 64 bit processors and to run it 64 bit OS's nb:we can run 32bit OS's in 64-bit processors we can't run 64 bit OS's in 32 bit processor , got it..

Well the most basic description is that a processor has two kind of buses(which can be considered to be thin wires carrying current/bits/information within and outside the processor chip).One is DATA BUSES and other is ADDRESS BUSES The larger the size of buses the better the cpu is. 32 bit processor means that all the data to be transported has to be transferred using 32 wires only. On the other hand, the 64 bit processor would be able to transport the same amount of information in lesser time duration as the number of wires are more in this case.:)
