That depends. The reason recipes tell you to preheat the oven is to get it to as stable a temperature as possible, so if you don't let it preheat enough then the temperature will continue to rise.
Also, whenever you open the door the temperature inside the oven drops. Even in the few seconds it takes to open the door, push whatever it is you're baking in and slam the door shut again the temperature can drop 20-30 degrees (fahrenheit). So even if you preheated the oven, its temperature will drop when you put the food in and increase over the next few minutes to whatever you've set the thermostat to.
People who bake bread sometimes preheat their ovens to 50 or more degrees higher than they intend to cook the bread at to counteract that drop in temperature when they open the door. Once the bread's in they reduce the temperature to the correct value. This helps the gas bubbles in the bread expand a lot immediately, before a crust has a chance to form, and results in higher and lighter bread :)
Baking ovens must have accurate thermometers to maintain a specific temperature. Proper, steady temperature is essential to producing good baked products.
Modern ovens can be set to an exact temperature for instance.
In italy. They used the thin flour to taste the temperature of ovens for baking bread
Until the pre-heat temperature you will be using is reached.

Combi Ovens allow for greater functionality and ultimately greater breadth of cooking and baking ability. These ovens are often much more costly than conventional ovens.
i affects by having different or specfific cooking or baking
Conventional ovens and some toaster ovens can be used to bake muffins. You cannot use a microwave oven to bake regular muffins.
Countries that use Celsius use it in their ovens.
I am pretty sure that most baking was done in fire brick ovens, like the Amish do now.
You can lower the temperature of the recipe by 25 degrees and cook for the full amount of time or you can take 10-15 minutes off of the cooking time at the original temperature.
Gas ovens and electric ovens should both be set at 325 degrees in order to bake a cake at 325 degrees. The type of oven used does not effect the temperature at which a cake is baked.
