    The term C MOS Stands for Complementery Metal Oxide Semiconductor is a technology used to manufacture IC s.These type of IC s include memories ,microcontrollers etc.
    The major example is the old CMOS BIOS PROM Chip which is overcome by flash Bios.
    The major advantage is Low Power requirements.

    The term N MOS stands for N type MOS technology used in IC industry for manufacturing.They are succeptable to noice and power requirements are higher than CMOS and are throw away by the CMOS.

    DUAL –CORE processors:

    Dual-core refers to a CPU that includes two complete execution cores per physical processor. It has combined two processors and their caches and cache controllers onto a single integrated circuit (silicon chip). ). It is basically two processors, in most cases, residing reside side-by-side on the same die.

    Or Simply:

    A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It’s the equivalent of getting two microprocessors in one.
    In a single-core or traditional processor the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. When data outside the cache is required, it is retrieved through the system bus from random access memory (RAM) or from storage devices.
    Accessing these slows down performance to the maximum speed the bus, RAM or storage device will allow, which is far slower than the speed of the CPU. The situation is compounded when multi-tasking.
    In this case the processor must switch back and forth between two or more sets of data streams and programs. CPU resources are depleted and performance suffers.

    In a dual core processor each core handles incoming data strings simultaneously to improve efficiency;when one is executing the other can be accessing the system bus or executing its own code.
