on x86-64 processors, yes. On Itanium, no.
Yes.
If you have a 32bit or 64 bit computer, you have to get the right itunes, or it wont work right.
32bit
Yes, except for Windows XP 64-bit and Windows Server 2003 64-bit with Itanium processors.
The Ubuntu/Kubuntu kernel is configured to support 8 processors / cores in 32-bit and 64 processors / cores in 64-bit.
Actually, they both make what are known as x86-64 processors, which are processors that can run both 32-bit and 64-bit programs. Check the specifications of the processor for something like "64-bit" or "64-bit Ready" to make sure you can run both x86 (32-bit) or x64 (64-bit) programs!
This applies to Windows XP and all 32bit or 64bit Windows Operating systems: 32bit Windows Operating systems are made to be used with 32bit motherboard/processors. All 64bit Windows Operating systems can only be used on a 64bit motherboard/processor and will not work with 32bit motherboard/processor architecture. 64bit Windows Operating Systems is also the only one made to utilize all of the processors on multi core processor (dual core, quad core, etc) systems. All Windows Operating systems are designed to function with a specific hardware architecture design. *some 64bit processor/motherboard combinations have a backward compatibility that allow you to use a 32bit operating system on a 64bit system by disabling 32bit. When you operate a 64bit processor in 32 bit mode it turns off some of the processors. This means a dual core will work as a single core, a quad core will work as a dual core (you can never get more the 2 processors to function in 32bit mode, even if there are more then 4 processors on the same processor die.)
what are the compitibility issues of 32-bit and 64-bit processor
Yes. x86-64 processors are capable of using both 32-bit and 64-bit operating systems and programs. Note that if you are using a 64-bit operating system, the system itself must be capable of running 32-bit binaries as well. Windows XP Professional x64 and 64-bit versions of Vista include this functionality. On Linux, since almost all programs come in a 64-bit version anyway, you have to install 32-bit libraries to run them.
Which group of Intel processors uses a 32-bit word size and a 64 bit word size?
yes 32bit and 64
All Intel Core 2 processors are capable of running in both 32-bit and 64-bit mode.
