Printed circuit board, or PCB, is used to mechanically support the electronic components and to connect them electrically using conductive pathways called tracks etched from copper sheets. Besides etched PCBs, there are Common or General purpose PCBs to make temporary or permanent circuits boards. Here explains the types of General purpose PCBs and the method of circuit construction on a Perf board.
Computers and many modern electronic devices rely on Memory devices to store and retrieve datas. These datas are used to direct electronic circuits for their action.
