Utility faucets known as hose bibbs that are installed at the exterior of a dwelling are also referred to as what type of cocks?

Utility faucets commonly found at the exterior of a dwelling are also referred to as bib cocks, making the term "bib" the correct choice in this context. The name "bib" comes from its design, which resembles a 'bib' due to the way it protrudes from the wall and allows hoses to be connected for various uses, such as watering gardens or washing vehicles.

While "sill cocks" is a term sometimes used colloquially, it refers specifically to the same type of faucet installed in a way that the valve is located below the frost line, which helps prevent freezing in colder climates. Thus, although "sill" may describe the location and function, it is not the generalized term for these exterior utility faucets.

A spigot often refers to a similar type of faucet but is typically used in reference to a faucet used for pouring liquids, like in barrels. "Stop" generally refers to a valve that can be turned to stop the flow of water but does not describe the faucet itself. Therefore, "bib" accurately captures the essence of the utility faucet in question.
