some are 64 - some are 32 ----- if you run DXDIAG you should be able to find out the model number if you do, just Google it!
Yes. All Core 2 processors are capable of running 64-bit programs an operating systems.
Yes. It can run either the 32-bit or the 64-bit version of Windows 8. I'd recommend the 64-bit version.
No, but the core 2 duo processors are: http://www.intel.com/products/centrino/compare.htm I also found this web page intersting: http://www.answers.com/topic/intel-core-cpu
No. The Intel Core Duo is a 32-bit processor. it is not capable of running 64-bit operating systems or applications.
No. Windows 95 requires a 32-bit processor (a 386 or higher). 286 and under processors won't work.
Yes, however this Intel processor is backwards compatible with earlier Intel processors and can run 32-bit, 16-bit, and 8-bit instructions.
Yes you can run Windows 32 bit on a Core 2 Duo CPU. But I would recommend you to go 64 bit instead as it is faster and can handle more memory, while 32 bit maxes out to 3.25 to 3.5GB of RAM. 64 bit can handle and use higher amounts of RAM and your PC will perform much better. I hope this answered your question.
Yes they can very well do as EM64T means Extended Memory 64-bit Technology which itself clarifies it
Both are impossible. An 80486 is far below the minimum requirements for Windows XP, and lacks certain instructions used by Windows XP that are only found in Pentiums and later. Examples include CMPXCHG8B, CPUID, and CMOV. The last version of Windows to officially support the 486 was Windows NT 4 and Windows 98. Windows ME and 2000 could be shoehorned onto it, but it ran extremely poorly.64-bit versions of XP only run on 64-bit processors, such as the Core 2 Duo or AMD Athlon 64. The 80486 is a 32-bit processor, so even if the above were not true, you couldn't run the 64-bit version.
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!
The 64-bit version of Windows Vista is designed to take full advantage of 64-bit processors, and can address more than 4 GB of RAM. 32-bit applications can still be run on it; however you will need to make sure that there are 64-bit drivers for your hardware.
Windows XP is almost NEVER in "64 bit". You have to specifically purchase XP 64 bit, as opposed to regular XP which is 32 bit. 64 bit processors will run 32 bit XP without problems, but you'll get a little more performance and some extra features (GUID partitions) on 64 bit windows. Once again - it's "always" in 32 bit, unless you go buy 64 bit.
