Q: What is a GFCI electrical outlet? Are outlets of this type required in all homes, and if so, where? –Allen D.

A: GFCI stands for ground-fault circuit interrupter. A GFCI outlet reacts much more quickly to the presence of an electrical short circuit than a standard circuit breaker does, so they provide additional protection against the possibility of injury should an appliance, tool or other electrical device malfunction.
