In hockey, the slot is the rectangle that extends toward the blue line and is the fourth position of a flying display. The word “slot” actually refers to two locations on the rink: a low slot that is directly in front of the goaltender, and a high slot that is in the middle of the ice above the face-off circles. The term is used in both field hockey and ice hockey. Here are some common slot terminology definitions.

A slot is an authorization for an airline to fly at an airport, usually when parking space or runway throughput is limited. These slots can be traded and are extremely valuable, with one selling for $75 million in 2016. Air traffic management slots are issued by organizations such as EUROCONTROL as part of their capacity and flow management role. The concept of slots has been around for almost two decades, but has only recently gained widespread acceptance. But it isn’t just airports.

A slot is an engineered opening, usually with 16 or 64 pinholes, that can accept various types of hardware. For instance, a memory card can fit into an expansion slot. A computer’s slot can expand its capability through the use of an expansion card. That is why almost all desktop computers come with expansion slots, ensuring that it will be able to expand its hardware capabilities in the future. And if you’re an urban teen, you can be a slot.
