32 bit and 64 bit Processor.
A 32 bit processor handles data in 32 bit chunks. A 64 bit processor handles data in 64 bit chunks. As a result, a 64 bit processor can handle twice as much data in one cycle as a 32 bit processor.
Cores: Cores are the number of processors. A single core system has one CPU which has one core.
A dual core system has one CPU with 2 cores in it.
So a 64 bit processor with 2 cores can handle 4 times as much data in one cycle as a single core 32 bit processor.
It used to be that in order to have multiple cores you had to have multiple physical CPUs. Most CPUs anymore actually have multiple cores on one physical CPU . This allowed for increased performance without having to increase the speed of the processors as the technology was running into physical limits of frequency (ghz) and processors could not be made to go much faster with current technology.
You can use a 32 bit operating system on a 64 bit processor and many machines do. The primary reason to use a 64 bit operating system at this point is that a 32 bit operating system can only address about 3.5 gigs of RAM and a 64bit operating system can address TBs of RAM, far more than is currently available in personal computers.
