The frog jumps on the lotus leaf, expressing a different state on each different lotus leaf. Jumping from one lotus leaf to another lotus leaf indicates the transition of state. The transfer process only depends on the lotus leaf where it is now, and is different from the previous one. The lotus leaves that have stayed are irrelevant. If you only consider the time sequence of the frog jumping, this process is a discrete-time Markov process. If you consider that the frog stays on the lotus leaf for a period of time, and this period of time obeys the exponential distribution, then this The process is a continuous-time Markov process. If the time is non-exponentially distributed, the process is half Markov.
