A slot is a narrow aperture or groove. It is usually round or rectangular but may be oval or square, and it can be used for a number of different purposes. For example, a slot may be used for holding a coin or key in a door lock, a hole to insert a card into an ATM, or a space to hang a picture frame. The word “slot” has a long history and is found in many languages. For example, it is closely related to the English word hole and the Middle Dutch word slot. A slot can also refer to a position in a group, series, sequence or other organization.

The slots are then managed by the content repository and rendered by the renderers.
A time slot is a specific period of time when a radio or television programme will be broadcast. It can also refer to a particular channel on a satellite or cable television system. The phrase can also be used to describe a specific time of day when something is done, such as a daily chore or exercise.
