A slot is a narrow depression, elongated opening, notch, groove, or aperture that accepts something, such as a coin in a vending machine or a letter in a mail slot. It can also refer to a position or place in an activity, such as a time slot on a TV broadcast or a slot in a theater play. The word is derived from the Latin slitus, meaning a split or hole. It is also related to the Greek spelota, meaning peg or dowel.
A graphical representation of the probability of a winning combination on a slot machine. In modern slot machines, the random number generator (RNG) determines the outcome of each spin. While many people like to play slots for the possibility of huge payouts, there is no guarantee that any particular machine will award a jackpot.
The house edge on a slot machine is the mathematical advantage that casinos have over players. The odds of winning a jackpot depend on the probability of matching a specific symbol on each reel, but even the most skilled player cannot predict which symbols will appear. This is because a machine’s RNG randomly assigns symbols to each reel and there are many possible combinations for every spin.
When a job’s capacity demands change, BigQuery dynamically evaluates the query’s dynamic data-aggregation graph and allocates or pauses its slots accordingly. This ensures that a job can use all its allocated slots without negatively impacting other jobs or query performance.
If a job is allocated more slots than it can use, the extra slots are used by other jobs until all the excess slot usage is covered. Any extra slots are not billed to the customer.
You can define custom slot types for your bot to identify and process different values in utterances. For example, you can create a location slot that maps to city names so the bot can find and book travel reservations. To define a slot type, click Add Slot Type on the Slots page and then choose a regular expression (regex) to match the value you want to map to the slot type.
When creating a slot type, you can also select synonyms to help the bot recognize variations of a particular entity value. For example, you can enter NYC in the Synonyms field next to a city name to ensure that the bot recognizes it when the user says New York.
