In programming languages, name binding or early binding is the association of objects (data and/or code) with identifiers.
An identifier bound to an object is said to reference that object. Machine languages have no built-in notion of identifiers, but name-object bindings as a service and notation for the programmer is implemented by programming languages.
Binding is intimately connected with scoping, as scope determines which names bind to which objects - at which locations in the program code (lexically) and in which one of the possible execution paths (temporally).
Use of an identifier id
in a context that establishes a binding for id
is called a binding (or defining) occurrence. In all other occurrences (e.g., in expressions, assignments, and subprogram calls), an identifier stands for what it is bound to; such occurrences are called applied occurrences.

정적바인딩(이른바인딩)은 실행시간 전에 바인딩해서 실행과정에서 변하지 않는 상태로 유지된다.
실행시간 전에 바인딩을 해야 하기 때문에 저장장소의 크기가 결정 되어야 한다.
속도는 빠르지만 그 코드는 그 코드, 그 함수만 실행이 가능하다..(실행과정에서 변할 수 X)
