The convection oven cooking is different from microwave cooking because of the different heating functions available in the oven:
(i) Convection function which transfers heat via the hot air circulation assisted by a fan.
(ii) Heating functions via the heating element i.e. top heater, bottom heater and grill.
Microwave oven heats food by passing microwave radiation through it and this wave make the food cooked from within the outer surface and the cooking time is shorter as compared to the oven cooking method.
