This paper refers to Definition of DualCore and compare it with solecore Processor and with dual processor as well. And also there is some technique in programming and CPU architecture like Multi Processing and Hyper Threading That we will discuss about them. As we know two huge company in CPU world have competition closely with each other. Intel and AMD have own design and technology in Dualcore processor that we will compare with each other.
