Rechenzustand

Rechenzustand, often translated as calculation state or computational state, is a concept used in computer science to describe the complete configuration of a computing process at a given moment. It includes the values stored in memory and registers, the current point in the control flow, and the status of input and output resources.

In theoretical models such as Turing machines and finite automata, the Rechenzustand refers to the machine's

In real hardware, the Rechenzustand is often called the processor or machine state and includes the program

Practically, managing the Rechenzustand is essential for debugging, error recovery, and fault tolerance. Techniques such as

Related concepts include state machines, program state, and the idea of stateless versus stateful computation. The
