**State machine replication** — Introduction from Schneider s 1990 survey: : Distributed software is often structured in terms of clients and services. Each service comprises one or more servers and exports operations that clients invoke by making requests. Although using a… … Wikipedia

**Finite state machine** — A finite state machine (FSM) or finite state automaton (plural: automata ) or simply a state machine, is a model of behavior composed of a finite number of states, transitions between those states, and actions. A finite state machine is an… … Wikipedia

**Nondeterministic finite-state machine** — In the theory of computation, a nondeterministic finite state machine or nondeterministic finite automaton (NFA) is a finite state machine where for each pair of state and input symbol there may be several possible next states. This distinguishes … Wikipedia

**Deterministic finite-state machine** — An example of a Deterministic Finite Automaton that accepts only binary numbers that are multiples of 3. The state S0 is both the start state and an accept state. In the theory of computation and automata theory, a deterministic finite state… … Wikipedia

This distinguishes … Wikipedia

**Event-driven finite state machine** — In computation, a finite state machine (FSM) is event driven if the creator of the FSM intends to think of the machine as consuming events or messages. This is in contrast to the parsing theory origins of the term finite state machine where the… … Wikipedia

**Virtual finite state machine** — The virtual finite state machine (VFSM) is a concept promoted by [http://www.stateworks.com SW Software] and implemented in their StateWORKS product. A VFSM is a finite state machine (FSM) defined in a virtual environment. The VFSM concept… … Wikipedia

**Extended finite state machine** — In a conventional finite state machine, the transition is associated with a set of input Boolean conditions and a set of output Boolean functions. In an extended finite state machine (EFSM) model, the transition can be expressed by an “if… … Wikipedia
