You will have been hearing about or seeing dual, quad, hexa, octa and other cores online or on gadgets specifications list. Processors are named according to their numbers of complete independent units known as cores. Dual as you already know means double or two, quad means four so same thing is applicable with processors. Dual core processors are processors made up of two cores. Quad core processors are made up of 4 cores and so on. So once the number of cores is high, the performance and task handling will be more faster.

Let imagine, a work to be carried out by four men of Group A and the same work to be carried out again by 8 men of Group B. This already clearly shows that Group B will finish the work before Group A finish their’s. Same thing is applicable to cores, when you have deca-core processor (10 cores), task handling will be faster than when carried out with hexa core processor (6 cores).
