When you open two windows in your Windows computer, the one you are viewing or handling is the active one and the other which goes at the backdrop becomes the inactive window. Similarly, when you tap on that window, it becomes active, while the window that was previously active goes to the background and turns inactive. The screenshot shown here will give you a better understanding.
