ADT
Home protection brand
ADT is a company best known for home security systems and monitoring services, with its distinctive yard signs and window stickers serving as visible deterrents to burglars.
The initials originally stood for American District Telegraph, reflecting the company's 19th-century origins in telegraph-based alarm systems.
In computer science, ADT separately stands for abstract data type, a theoretical model that defines data structures by their behavior rather than implementation.
