A jump process is a loose term describing a stochastic process that has discrete movements, called jumps. The jumps may arrive at fixed times (e.g., binomial model), predictable times (e.g., jump occurs when, say, a one-dimensional Brownian motion hits, say, value 1) or at totally inaccessible stopping times (e.g., the jumps of a Poisson process).
