MOTHER BOARD

                                                                MOTHER BOARD

                      

                                    Mother board are the largest circuit board used inside a computer . All the devices inside a computer are connected to the mother board. According to the generation of mother board       it is classified in to three.

1. Passive
2. standard or active
3. Integrated  

   
   1.Passive

                It contain power connector, DIN port and  expansion slot. For any works to be performed we have to add corresponding  daughter board or Add on cards.

   

   2.Standard/Active
   
        A standard mother board integrates memory module and processor to a passive mother board.


   3.Integrated 

        The family of integrated mother boards integrated more components. So that we can reduce the use of daughter boards. Integrated mother boards are two types Partially integrated and fully integrated.
