I wonder what's the difference between a dual core computer and a computer with 2 processors on the mother board.. I think it's something related with the threads but a I don't understand it very well..

Multiple processors let your computer do literally two things at once (instead of only seemingly doing two things at once, but actually just swapping between tasks extremely rapidly).

Multiple cores are the same. The advantage of multiple cores over multiple processors is that they share some bits of the CPU, e.g. the second level cache, which makes it possible for them to work even more efficiently if they have some shared data. This makes them much cheaper to manufacture. A single dual-core CPU also takes up less room than two single-core CPUs, which is an important factor these days with everyone moving to laptops.

There may be some performance differences, but nothing you're likely to notice.
