The Actor Model

The Actor Model is a framework for designing computer systems that treats "actors" as the fundamental units of computation. Each actor is an independent entity that can send messages, receive messages, and create other actors. Instead of sharing data or state, actors communicate purely through messages, which helps manage complexity and allows for easier scaling in distributed systems. This model is beneficial for building applications that need to handle many tasks simultaneously, like online services or games, as it simplifies concurrency and enhances fault tolerance.
