What Is a Slot?


A position or berth in a group, series, sequence, or arrangement. Examples: a berth in a boat, a slot on a train, or a time slot for an appointment.

A slot is the operation issue and data path machinery surrounding a set of one or more execution units (also called a functional unit) that share these resources. It is also known as an execute pipeline. This concept is commonly used in very long instruction word (VLIW) computers.

In electromechanical slot machines, the taste was often a small amount paid out to keep a player seated and betting for longer than they might otherwise. This was done to circumvent the law against gambling machines that required players to insert coins or tokens.

Modern slots use microprocessors to determine where the symbols land on the reels. They use a random number generator to do this, and each spin results in a different combination of symbols. Many machines offer multiple pay lines, and some include wild symbols that act like a joker, substituting for other symbols to make winning combinations.

A slot> element has a name attribute that specifies the value of a variable within a child scope when the slot is rendered. The value of this variable can then be accessed by expressions in the slot’s content. This is similar to how a dynamic scoped directive works. Note that the v-slot shorthand # can be used in place of the named slot argument, for instance template v-slot:header> can be shortened to template header:hello>>.
