in a 64 bit computer is that is capable of transfer 64 bit at a time 64 bit os means it capable of handle these 64 bit at time .but 32 it os use only half of bus so "theorytically not practically" 64 bit is 8 time faster than 32 bit os . and 64 bit os can address more ram at time . cause of wide 64 bit address bus. this architecture is called x-64 based bit and 32 bit os is called x-86 based architecture. as we know that when be some compiler are capable of install on both type of os 32 and 64. that compiler will use 32 bit based addressing system that result sizeof address 4 byte. if your compiler is completely build for 64 bit os that definitely it has to use 64 bit address lan that require 8 byte size integer size to hold this wide address.
so there for 3 type of os is available in market x86 x64 x86 x64 now Windows 8 will come with 128 bit addressing system i hope this can make you more clear -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
