Aktordrivsystems

An aktordrivsystem, also known as an actor-based system, is a model of concurrent computation in which the basic unit of computation is an actor. Introduced by Carl Hewitt, Peter Bishop, and Richard Steiger in 1973, the actor model is a mathematical model of concurrent computation that treats "actors" as the universal primitives of concurrent computation. Actors are computational entities that can receive messages, send messages, and make local decisions. They encapsulate state, behavior, and a mailbox for holding messages.

Key characteristics of aktordrivsystems include:

1. Isolation: Each actor operates independently and maintains its own state.

2. Asynchronous Communication: Actors communicate with each other through message passing, which is asynchronous and non-blocking.

3. Encapsulation: The internal state of an actor is hidden from other actors, promoting modularity and reducing the risk of unintended interactions.

4. Dynamic Creation: New actors can be created dynamically, allowing for flexible and scalable systems.

Aktordrivsystems are particularly well-suited for applications that require high levels of concurrency, fault tolerance, and scalability. They are used in various domains, including distributed systems, real-time systems, and multi-agent systems. Examples of technologies and frameworks that implement the actor model include Akka, Erlang, and Scala's Akka library.
