Motherboard is the real state of computer. All the computer ports [input,output,processing] are connected in this board.Motherboard is made by using fiber glass materials on which conductor circuit are printed.
Motherboard PCB may have 4 to 16 layers on each layer various circuit are printed. Inner layer of the board contains circuit for data & outer layer are used to carry power signal and control signals.
Various parts ,slots,headers& socket are inbuilt on Motherboard which are used to connect input,process and output parts.
Back parts of Motherboard
