A slot is a narrow notch or groove, as in a keyway in machinery or a slit for a coin in a vending machine. The word is also used to refer to a position in a group or series, such as a time slot on a schedule.
The word can also refer to an opening in a wall or door, or the space between them. If you want to fit something into a slot, you need to make sure that it is the right size for the space. For example, you can slot a piece of wood into the hole in your wall to build a picture frame. You can also use the term to describe a time period, such as a day or night.
A slot can also be a part of a computer’s motherboard, and is used to hold expansion cards such as an ISA card or a PCI card. It is usually labeled with its function. There are also several slots on a motherboard for memory chips. In addition, some slots are a special type of socket that can be connected to a power supply unit.
