64 bit OS and 32 bit OS. diff?
What is the difference between 64 bit OS and 32 bit OS.
64 bit OS may use inverted page tables, What else?
A 64-bit OS needs to have full support for 64-bit hardware plus support for 32-bit legacy programs.
A 64 bit OS is one that takes advantage of an underlying 64 bit hardware architecture. That means that typically the registers would be 64bitswide and integer operations would occur on 64 bit values. Also typically hardware architectures don't have such simple changes as simply lengething the registers - so a typical OS would utilise the newfeatures of the hardware.
I don't know what inverted page tables are, can you tell me ?You can read a little about the new IA64 acrhuecture here: (veryinteresting)http://msdn.microsoft.com/msdnmag/issues/01/06/hood/
http://msdn.microsoft.com/msdnmag/issues/01/07/hood/Win 2003 server has a 64 bit version along with a host of other coolthings.
