What is the order of execution scripts?

Questions & Answers
1

For example, I have two objects and two scripts with Update() method only, in what order they will be executed?
Another example, one script generating array, another script using this array as a parameter for moving objects (for example). How can I strictly define their order of execution? (firstly I updating array, after this I moving objects; array updating every frame, Start() not suitable for this situation).
