For example, when the piston moves from the bottom of the cylinder to the top, this is called a stroke. One stroke is defined as the maximum distance a piston moves when traveling from the top of the cylinder, to the bottom of the cylinder, or vice versa.

there is one stroke for each of the suction, compression, power, and exhaust stages. It’s called a four-stroke combustion engine because there are four strokes to one combustion cycle.
