There are 2 types of noises in communication system. External noise and internal noise. External noise contains atmospheric noise, extra terrestrial noise and industrial noise. Internal noise contains thermal agitation noise (white or Johnson), shot noise, transit time noise, flicker, resistance noise etc.
