Handles
Doors generally have at least one fixed handle, usually accompanied with a latch.

Latch – A device that allows one to fasten a door, but doesn't necessarily require an external handle
Bolt – A metal shaft usually internal to the door, attached by cleats or a specific form of bracket, that slides into the jamb to fasten a door.

Strike plate – A plate with a hole in the middle made to receive a bolt. If the strike is for a latch bolt, it typically also includes a small ramped area to help the bolt move inward while the door is being closed.
