Technically no. A bit is an electronic circuit therefore a processor that uses 32 bits can't be swapped out for one that uses 128 bits, because the 128 bit processor, because the other 96 circuits don't have anything to connect to. However, you can emulate a 128 bit processor with a 32 bit processor if the 32 bit processor is fast enough, or if you have a multicore processor. For example a quadcore 32 bit processor has 4 cores which handle 32 bits each, so using all 4 cores together you could process 128 bits all at once. If you run a dualcore 32bit processor using both cores you would have 64 bits and would have to run the processor twice as fast as the 128 bit processor to handle the same amount of data. A single core 32bit processor would then have to be run at 4 times the speed.
is the processor with dual cores.
The highest number of cores in a single processor chip for consumers (high end servers) is the AMD Opteron 6000 series, with 16 cores per processor, and quad processor motherboards allowing for a total number of 64 x86 cores.
6 cores
Four independent cores into a single package composed of a single IC. A dual-core processor contains two cores, and a quad-core processor contains four cores.
XP Home Edition is limited to one processor DIE. It can have any number of CORES. XP can see all of the cores of a Core 2 Quad, for instance. Even if the system in question had two separate die, or chips, XP would still work. It just wouldn't be able to use the second processor.
dual core
For Intel chips this will be almost any Core I5 and I7(with the ones ending with 3 numbers and X being Hexacores, the rest are just Quad cores), for AMD that would be the Chips with "X3 (3 physical cores)/X4(4 cores)/X6(6 cores) in the name.
The simplest method is to view the Task Manager (press Ctrl-Alt-Del) and view the CPU performance charts. A chart is provided for each processor core, so if the number of charts is equal to the number of cores in your processor, you will know that they have all been detected and activated.

Two physical cores and two virtual cores.
seems you are a bit confused there,eh! it seems that u mean uni-core-processor and multi-core-processor. uni simply means 1 so its obvious it is a single core processor. (for eg. Pentium 4's) multi means multiple, so its obvious it is a multiple cores processor. (for eg. core2duo has 2 cores, core2quad has 4 cores, phenom ii x6 110t has 6 cores and so on)
