Let me just add a clarifying remark....

Why is it that EVERY (and I mean EVERY) - TV set, Air conditioner, DVD player, Digital camera, Motor car, Motor cycle, Microwave oven, desktop printer, ANY (and all) remote control handsets, Traffic lights, Commercial two way radios & the list goes on with pretty well anything that is controlled by an electronic 'brain' - in EVERY case these devices are ALL controlled by embedded processors NOT (repeat) NOT a Personal Computer (PC).

Ask yourself why that is................
