 * <p>A converter always converts {@code null} to {@code null} and non-null references to non-null
 * references. It would not make sense to consider {@code null} and a non-null reference to be
 * "different representations of the same information", since one is distinguishable from
 * <i>missing</i> information and the other is not. The {@link #convert} method handles this null

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

### Concurrent Burgers { #concurrent-burgers }

You go with your crush to get fast food, you stand in line while the cashier takes the orders from the people in front of you. 😍

// as an argument.
func ExecObjectLayerAPINilTest(t TestErrHandler, bucketName, objectName, instanceType string, apiRouter http.Handler, req *http.Request) {
	// httptest Recorder to capture all the response by the http handler.
	rec := httptest.NewRecorder()

	// The  API handler gets the reference to the object layer via the global object Layer,

이것은 어느 정도 "고급" 개념입니다.

**FastAPI**를 처음 시작하는 경우 지금은 이 부분을 건너뛰어도 좋습니다.
