Complex sentence: The Brownian motion process and the Poisson process (in one dimension) are both examples of Markov processes in continuous time, while random walks on the integers and the Gambler's ruin problem are examples of Markov processes in discrete time.
Split into simpler sentences: The Brownian motion process and the Poisson process (in one dimension) are both examples of Markov processes. These two processes are Markov processes in continuous time, while random walks on the integers and the Gambler's ruin problem are examples of Markov processes in discrete time.
