The slots on the sides of a computer monitor are used to display sounds and video images. A slot can also be used to store information such as program code or data. Slots are commonly found in computers, television sets and video games.

The most common type of slot is the mechanical one. Charles Fey’s invention of the machine allowed automatic payouts and had three reels, which increased the chances of winning. Fey replaced the poker symbols of the Sittman and Pitt invention with more exciting icons, including hearts, horseshoes, diamonds, and Liberty Bells. He designed the slot machine so that three aligned Liberty Bells were the highest winning combination.

Modern online slots offer a variety of interesting bonus features and jackpots. Some have more than fifty pay lines, and some include games you can play in addition to pulling the handle. This variety is a major reason why slot machines remain popular.

A slot is also the name of a place in a group, series, or sequence. It can also refer to an assignment or job opening: He was assigned the slot as chief copy editor.

In computing, a slot is the area where applications can run. Each application has its own set of slots, and each resource can be assigned a slot or multiple slots. When a resource is not assigned to a slot, it inherits the slots of its parent folder or organization (if any). When a reservation is autoscaled, the assignments for all its resources are automatically scaled up and down.
