Pacman is Pix-elated!


Look closely at the picture of the video games  you played during your childhood , you will notice that it is made up of tiny colored dots or squares!!!The screen of a computer works just like a TV set .The picture consists of a grid of cells called pixels(each pixel has 3 coloured dots:blue,green,red).This grid has vertical and horizontal  position codes and a colour code.So the work of the microprocessor is to generate the picture using a series of codes.
