Is This Answer Correct? AWT is heavy-weight components, but Swing is light-weight components. We can change the look and feel in Swing which is not possible in AWT. Swing takes less memory compared to AWT. For drawing AWT uses screen rendering where Swing uses double buffering. A heavyweight component is one that is associated with its own native screen resource commonly known as a peer. A lightweight component is one that "borrows" the screen resource of an ancestor which means it has no native resource of its own -- so it's "lighter".

Double buffering increases data transfer speed because one buffer can be filled while the other is being emptied. Changing the state of an object is called an event. An event handler is a part of a computer program created to tell the program how to act in response to a specific event. A layout manager is an object that is used to organize components in a container.
