The lollipop, a small circle on a stick represents an implemented or provided interface. The socket symbol is a semicircle on a stick that can fit around the lollipop. This socket is a dependency, needed or required interface.
Provided and required interfaces define behavior of component.
Component functions are defined using provided interfaces. A required interface defines what functions or services it requires from other components.
