Dual Core - definition
CPU is the block that is designed with a few millions or billions of electronic transistors to execute computer instruction. Previously, there was a single core processor which had only one core in an entire processor. But nowadays, advanced CPUs have more than one core, which could be two (2), four (4), six (6), Eight (8), or more.
In the dual-core, there are two (2) cores, which can be differentiated as the primary core and the secondary core. In case of heavy processing, both of the cores get activated and execute the instruction set assigned by the program, in other times, the secondary core can be shut down or stay idle to save power. Or one core might handle heavy lifting programs and one may do the basic tasks depending on the situation. i.e.: Intel Pentium 4 or Snapdragon 208.
