ICA: Differences Between Single Core Processor and Multi-core Processor

  In brief layman term, multi core processor are capable of completing task in a parallel way or pipelining . As few task are being executed simultaneously, but the software are required to optimise for multicore processor to fully utilise and maximize the full potential of the multicore processor. Where by single core processor are less efficient in multitasking though it is capable of it through specific software such as the Intel Hyper Threading Technology.
  Example of multicore processor such as the Intel Core i Series, AMD Phenom etc.
