A slot is a narrow opening in something, often used to accommodate a small piece or device. It is a feature that can be created by cutting or machining. A coin is dropped into a slot to make a machine work, for example. A person can also use a slot to dial a telephone number.
A slot can be found on a computer, for instance, to store files and applications. It is a way of keeping important data organized and secure. Another useful application of a slot is to allow for the transfer of information between two devices. For example, a laptop and a desktop computer can communicate with each other through a slot.
In sports, a slot receiver is one who receives the ball on running plays like slant routes and sweeps. They are usually closer to the line of scrimmage than other receivers and more vulnerable to big hits. However, they are important for running game success as they can block for other runners and help avoid being hit by defenders trying to tackle them.
