PCB stands for Printed Circuit Board. It is a thin board made of fibre glass containing electrical wires which connects the central processor to the other components on the board.Printed Circiut boards in short are called as PC Boards as we use these boards in our personal computers.Other than personal computers there is a wide range of application for PCBs in radio,television,music players etc. PCBs provide mechanical as well as electrical support to the electronic components.If the board has only copper tracks and no circuit elements like resistors,capacitors,these PCBs are called are Printed Wiring Board(PWB).A PCB populated with electronic components are called as Printed Circuit Board Assembly(PCBA).
