    Re: FSM

    Hello Muhamed,

    Keyword breakdown is Finite (vs Infinite) and State.  I would consider this known states....

    Here is an excerpt form the TCP/IP Guide:

    One way that computer scientists explain how a complex protocol works is through a theoretical tool called a finite state machine (FSM). An FSM attempts to describe a protocol or algorithm by considering it like a virtual “machine” that progresses through a series of stages of operation in response to various happenings. You need to understand four essential concepts to comprehend the workings of a finite state machine....

    ....A FSM describes the protocol by explaining all the different states the protocol can be in, the events that can occur in each state, what actions are taken in response to the events and what transitions happen as a result.The protocol usually starts in a particular beginning state when it is first run. It then follows a sequence of steps to get it into a regular operating state, and moves to other states in response to particular types of input or other circumstances.

    Re: FSM

    It's a machine (system, entity, thingy, something) that can be in various states, and that list of states is very defined. By nature of the design of the machine, it can only exist in one of the predefined states, never in more than one at the same time, and never NOT in one of the defined states.
