Mother board: Mother is a heart of the computer and its also reffered as system board or main board.all the components of the computer connect direct or indirect to the mother board.it is a main circuit board inside the machine without mother board anything is run in computer.it contain some non-volaitle memory to intilaze the systemand load the operating system in peripheral devices.most of the mother board design bios,EEPROM CHIP store the bios and socket in the mother board to boot strap and operating system.the power is applied on the mother board bios firmware test and confugries the memory circuitry and peripheral.mother board contain one or more cpu supporting circuitry.intergarted circuits provide interface between cpu memory and input/output periherpal circuit and main memory.it is usefull for intial set up of computer immediartely after power on the system.the cpu plugs into the all of the card on the mother board sound card is the one of important card in mother board.it contains the connectors to attach the additional boards.mother board contain cpu
