Different examples of Markov processes for different levels.

	Countable state space	Continuous or general state space
Discrete-time	(Discrete-time) Markov chain on a countable or finite state space	Markov chain on a measurable state space (for example, Harris chain)
Continuous-time	Continuous-time Markov process or Markov jump process	Any continuous stochastic process with the Markov property (for example, the Wiener process)
