In ice hockey, the low slot is an area on the ice where center and wingers have the best opportunity to shoot the puck past the goalie without deflection. It is often referred to as the “no man’s land” because of the advantages that attackers obtain there.
An authorization to take off or land at a specific airport on a particular day during a specified time period. Air traffic controllers use slots to manage flight operations at extremely busy airports and prevent repeated delays from aircraft trying to take off or land at the same time.
In computer programming, a slot is a container for data that can be accessed by multiple components. For example, a template could include a slot called ‘header’ that is rendered in the header of the parent component. This slot would be accessible by the child component and could contain its own data. The slot could be configured to show or hide the content. This feature is also referred to as data binding or parameter passing. Using slot allows developers to avoid duplicating code in multiple places.
