Yes, as per the definition in richardfontana's comment. Some ovens in the UK have separate upper and lower compartments, and the smaller one can be switched between an oven and grill function, in which case the heat radiates from the top. This is also used for making toast.
In the US, this is usually called the "broil" setting. The gas ovens usually have the lower compartment for broiling but electric ovens just use the top heating element in the main compartment.
Sure, if you don't have a toaster....
Gas grills make good-tasting toast and they're less problemmatic to do cheese toasties in than a toaster... .
