A slit or narrow opening, especially one for receiving something, as a coin or letter. Also: a position or assignment within a group, sequence, etc.; a position of employment or a job title (e.g., Chief Copy Editor).
In computer programming, a slot is an operation issue and data path machinery surrounding a set of one or more execution units, sometimes called a pipeline. A machine with multiple slots may share some of the same resources, such as cache and memory.
The term is used in very long instruction word (VLIW) computers, where the relationship between the operations in an instruction and the pipeline to execute it are explicit. The VLIW model has the advantage of separating the instruction-processing hardware from the data path. This makes it much easier to optimize the performance of a machine by changing instructions rather than the data path. In dynamically scheduled machines, the concept is similar, although it is not as well defined, and the term is more commonly used to refer to an entire pipeline of instructions, rather than individual operations in the instruction.
On a slot machine, players insert cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode, into a slot at the top of the machine, then activate the machine by pressing a lever or button (either physical or on a touchscreen). The reels spin and when the symbols line up on a payline, the player earns credits according to the machine’s payout table. Many slots have a theme, with classic symbols including fruit, bells and stylized lucky sevens.
Slot receivers are normally shorter and stockier than the typical wide receiver, but they must be quick with precise routes and timing. They also need to be able to block, particularly on pitch plays and reverses. Some slot receivers also act as ball carriers on end-arounds and other running plays.
Using central flow management in airports, or in other air-traffic areas, allows aircraft to fly at their optimal speeds. This reduces congestion and the need for fuel burn to keep pace with other traffic. It also allows for longer runways and more efficient flight paths, which reduces delays and reduces the environmental impact of aviation.
The most valuable wide receivers are versatile, and can do a little bit of everything on offense. Tyler Boyd, Cooper Kupp and CeeDee Lamb are all examples of this type of receiver. They all can run the deep routes, out-route and slant patterns required of the slot receiver, but they also are good at running after the catch, can play some tight coverage and can contribute on special teams.
In order to maximize their effectiveness, slot receivers need to be on the same page as the quarterback. They need to have an advanced understanding of the field, which allows them to anticipate where defenders are going and when. This is why they need to be in the pre-snap motion as often as possible.
