A dual processor is a processor that has two independent processors into one package called a single integrated circuit. A dual core instrument has two separate microprocessors. The cores in the dual processor can share one coherent cache that is placed at the highest cache level. Processors do depend on two one of a kind sources of memory so it can hold onto specific information while it is processing others. Ram stores information that is being used at that moment. While a second storage space is called cache. There are two caches that the processor can take from. They are generally slow but they are faster than the RAM or even the hard drive.

You can dual process through a process called Symmetric multiprocessing. This does have more than one processor that is associated with the same RAM and the same hard drive. There is also the AMP which is the Asymmetric multiprocessing which shares the RAM and has other resources with more than one processor. So to recap, a dual processor is two processors in one box one using RAM and the other using cache. You can either split the load of the processor or share it depending on what information you want to share. Make sure that if you upgrade to a dual processor that your operating system and applications can handle them.
