Scope (computer programming)

In computer programming, the scope of a name binding (an association of a name to an entity, such as a variable) is the part of a program in which the name binding is valid. In other words, a scope is where a name can be used to refer to an entity. In other parts of the program, the name may refer to a different entity (it may have a different binding)…
