computer
Computer keyboard contains PCB(circuit board) which transfers signals to computer and 2 thin conductive layers. Under every key is conductive crossing of the two. When pressing a key, electrical contact inside gets closed, then computer receive current which flown through it and recognizes which key was pressed.
A computer program contains instructions, to be executed by a computer.
