Answer
Value types: store data directly (int, bool, double, struct).
Reference types: store a reference to memory (class, interface, array, string).
Quick Answer
Value types (int, bool, struct) store their actual data on the stack — copy one and you get two independent values. Reference types (class, string, array) store a pointer on the stack to heap data — copy a reference and both variables point to the same object. This distinction matters a lot when passing objects to methods.
