Some of you may get confused by dual core and core 2 duo as it seems to be entirely different concepts.Dual core processors are like two processors working in serial i.e the two processors do the same job at a given time.The core 2 duo is working in parallel i.e they divide the work between them.Now the latest processor by intel is i7 processors.
