Final answer:
The Action Center is commonly located on the right side of the screen, serving as a notification and settings hub.
Step-by-step explanation:
The Action Center in the context of a computer's user interface, such as that found in Microsoft Windows, is typically located on the right side of the screen. It is a component that aggregates notifications and provides quick access to various settings. When you click the Action Center icon or swipe in from the right edge (on touch screens), it slides out as a sidebar, showing notifications from apps and providing quick toggles for settings like Wi-Fi, Bluetooth, and screen brightness. So, the correct answer is that the Action Center is usually found on the right side of the screen.
