What Is a Slot?

A slot is a small opening or groove that receives things. It can be a place in a building or an airplane wing, where it’s opened to improve airflow. It can also refer to a grammatical word that fits any morpheme sequence in a given context, such as an interior space on a copy desk or a job title at a newspaper.

A computer expansion slot was designed to make processor upgrades easier. It was first released by the Intel Corporation in 1997 and later by AMD. However, it’s now rarely used in new computers because sockets are more compatible.

A SLOT is an acronym for “slave of technology.” It’s a term that’s commonly used to describe a person who’s obsessed with gadgets and technology, usually a boy or a girl. It could also be a name or a nickname for an individual.
