slots

Quantities of slots are numeric measurements of holding capacities for specific objects, including parking and storage spaces. This includes clearly quantifiable slots as well as roughly quantifiable spaces where individual slots are not drawn or clearly defined but can nevertheless be quantified with reasonable accuracy.

The quantity concerns places available to hold a specified kind of object. It can be exact where spaces are marked or an approximation where the arrangement is flexible.

The number of available places is distinct from the number currently occupied. A parking area can have empty slots, and a storage area can have unused capacity.
