What is a slot? What are its uses and functions? These are some questions that every beginner should have in mind. Hopefully, this article will help you identify a slot. This article has also provided you with the origin of the word “slot.”

Origin of the word

The word “slot” is a medieval English word that referred to a hollow in the throat above the breastbone. It derives from Old French and Old Norse. The word was first recorded in English in the early 1520s. The term “slot machine” dates from 1888. The word is also used in popular culture to describe a type of slot machine. The origin of slot is not entirely clear, but it likely has its roots in the Middle Ages.

The term “slot” refers to several different things. It is sometimes a family name. Often it is a given name. It is also an interchangeable unit. It may mean a coin, a mail slot, a television program time slot, or an aperture. It has many meanings and is often used in a broader sense to mean “hole” or “crack.”


The word slot has multiple meanings. It can refer to a place, time, or aperture, and it is a general word for “hole” or “crack.” The earliest recorded use of slot dates to the early 14th century. This definition is also relevant to many other similar words. Read on to find out the meaning of slot in context. Listed below are some examples of slot usage in the modern world. These examples demonstrate how the word “slot” has evolved throughout history.

The definition of slot is a small opening or hole in something. In everyday life, a slot can be an airfoil gap or a mail slot. However, it also refers to a grammatical construction. Slots are usually used to describe position. For example, a slot in the copy desk is occupied by the chief copy editor. In the aviation industry, a slot in the runway is an authorization given by the air-traffic authority.


If you want to send data to another location, you can use slot functions. The signal that connects to a slot function is immediately executed, regardless of whether the device is in an active state or not. However, you should avoid calling slot functions too often as they can increase the overhead of the app. Moreover, these methods are generally slower than callback mechanisms. The difference between the two methods lies in how they handle heavy workloads. Let’s look at some of their advantages and disadvantages.

First, slots are useful for communication. In component programming, they can be used to connect objects. This is because they use signal information to communicate. Slot functions can have a variable number of arguments, as opposed to static functions. For a simple slot, you can use the $passSignalInformation parameter. However, if you use a signal with variable number of arguments, it can get confused and cause unexpected results. Therefore, you should use the $passSignalInformation parameter.

Identifying a slot

One of the most common tasks of an expandable content display system is identifying a slot. Slot identifiers are entries in a content database that identify the slot and the resource identifier of the corresponding electronic publication. When a user requests content through the display system, the data processing system determines whether the slot is permitted to expand in the specified direction. It then selects the expandable content item for publication.

The CPU first checks a slot’s state for percussion sound. The CPU sets state bit S1 to 1 if the slot has percussion sound. When the slot has a mask bit, the CPU will not process the slot. Instead, it will perform steps S5 to S11, if the slot is idle. Then it will continue to process the percussion sound, if it’s present, and it must equal the state bit S4.
