While in a continuous function graph, the points are connected with an unbroken line. Discrete data contains distinct or separate values. Continuous data includes any value within the preferred range.

This paper presents an approach for representing functions of discrete variables, and their products, using logarithmic numbers of binary variables. Given a univariate function whose domain consists ...

But some dissidents argue that only space or only time should be discrete. So how can physicists find out whether space-time is discrete or continuous?
