Scope.
Explanation:
In programming, the scope could be static, private or public and in those, defines the scope of a specific variable.
Ex.
public int x = 0; // Can be seen when called within a whole class and outside of a class/ function.
private int y = 0; // Can be seen only within the class its defined in.
static pub/priv int z = 0; // Uncangeable variable that can be defined in both class and external class, depending on the two prior scopes defined after.
int aa = 0; // Defaults to private.
