hi ceans,

I want to know about waht we actually mean when we say that this processor is dual core or quad core & this processor has 2 or 4 cores on its chip.

How this can improve performance of microprocessor ?

-A multi-core processor is a processing system composed of two or more independent cores
-multiple CPU cores on the same die allows the cache coherency circuitry to operate at a much higher clock rate than is possible if the signals have to travel off-chip
-combining equivalent CPUs on a single die significantly improves the performance of cache snoop (Bus snooping) operations
-a dual-core processor uses slightly less power than two coupled single-core processors
-For example, if the automatic virus scan initiates while a movie is being watched, the application running the movie is far less likely to be starved of processor power, as the antivirus program will be assigned to a different processor core than the one running the movie playback.

From a layman's perspective, a core is part of the microprocessor which does the processing. (Correct me if I am wrong)

To improve the performance of the processor, you may consider overclocking your CPU. But sometimes overclocking may be harmful for the CPU.

thanks,

mahesh_dahale can you just explain any thing more about this line.
