What is dual core processor?

A dual core processor is a CPU with two processors sharing the same cache memory. Because concentrating the processing power on a single CPU is becoming very expensive, the trend is to distribute power over two or more core. The speed of the two core are the same and the performance of the system is better only if you use software designed for this type of processors. If you use software developed for a single processor you can't see any performance improvement. The main software which have to be designed to use dual core processors is the operating system: in fact nowadays Linux, Mac Os and Windows Vista can use multicore processors quite fine. There also are many software that can exploit multicore processors like photoshop .

I know the people before me answered this but as i read, it was a bit technical. In Layman terms, it speeds up your computer big time. The Core 2 Duo (dual core) is getting cheaper since the Quad Core is out. But Intel is still developing a better dual core and quad core system.

I read some information on the dual core processor but it didn't make much sense to me. I am not a "whiz" on the computer or various components. Here is something I found that you may want to read: http://www.wisegeek.com/what-is-a-dual-core-processor.htm

well a dual core processor is a device that transmits data from one computer.to the next.plus it helps every thing in the computer run faster and u dont bye one seperatly it all ready comes with one when you bye.A computer
