What is a Slot?


A slot is a narrow notch, groove, or opening, typically one for receiving something, such as a coin or a letter. It may also refer to:

A position or place in a sequence, series, or arrangement. “They slotted in at the end of the line”

A vacancy or opportunity. “I’m looking for a new job, and I’m hoping I can find a slot somewhere.”

In computer science, a slots are the positions in a motherboard for expansion cards such as an AGP or memory card. They are often numbered, and the numbering is usually defined by the type of card. Some slots are reserved for specific devices, such as video cards or sound cards. Others, such as the PCI or ISA slots, are available for use with any card that fits within them.


In NFL terms, the slot receiver is the second wide receiver on the team. They are expected to run many routes, be precise with their timing, and have great chemistry with the quarterback. These players are vital to the success of a team, and some have even become hall-of-famers.

Another important aspect of slot is their ability to block. Having good blocking skills is crucial for a slot receiver, as they will not have a fullback or extra tight end to help them out. They must be able to protect themselves, as well as take the ball away from defenders.

An airport slot gives an airline the right to operate at a certain time, such as during peak hours when traffic is high. It is a way to prevent delays and reduce fuel burn. Air traffic management slots are issued by EUROCONTROL, as part of its Flow Management role.

A slot is a thin opening in a thing, used to accept something such as a coin or a key. The word is derived from the Old Norse word slod, meaning a track or trail. The term is also used to describe an appointment or a position, as in “He has a big slot as chief economist.” In computer science, a slot is a position or gap in a device’s firmware that allows for the installation of software programs and drivers. The slot can be created by modifying the firmware, creating a kernel image, or using a bootloader to create a custom loader. A slot can also be created in a hard disk or USB drive by adding a program file to the device’s system image. The device’s firmware will then search for the program and install it if found. If the firmware cannot locate the program, it will continue searching and eventually find a suitable slot. The device will then reboot and begin operating with the new software. This process can be reversed by reverting the firmware to the original state. In addition to the hardware slot, some operating systems support a software slot for applications. In some states, private ownership of slot machines is prohibited, while in others, only machines older than a certain age are permitted.
