These technologies include largescale network performance measurement and management tools, secure identity and access management tools, and capabilities such as scheduling high-bandwidth, high-performance circuits [4].
The circuit is made, electricity flows to the light fixture and the light turns on. When the homeowner turns the light off, the moveable contact attached to the operating mechanism breaks from the fixed contact. The circuit is broken, electricity stops flowing to the light fixture, and the light turns off.
