Ada language is required for our experiments in concurrent distributed systems.In layman's terms, the ADA language is a particularly detailed language (highly specific), so it is characterized by a large number of checks at compile-time and runtime that can pinpoint the wrong location and type more precisely (because the language itself is exhaustive, the more information you provide, The compiler can do m
