Abbreviation for 'bits per inch,' a measurement of data density or resolution used in computing, data storage, and digital recording technologies.
From English initials: 'bits' (binary digits, fundamental units of information), 'per,' and 'inch' (unit of measurement). This technical acronym emerged in mid-20th century computing.
BPI represents how computing vocabulary borrows from traditional measurement language—'bits per inch' mirrors 'dots per inch,' helping non-technical people grasp digital concepts through familiar metaphors of density and space.
