Question

A "black box" has an interface and an implementation.

Which of the following statements describe interface?

Select one:
a. The interface of a black box is its connection with the rest of the world,
such as the name and parameters of a subroutine.
b. The interface refers to internal workings of the black box.
c. The interface is a parameter used by the program.
d. None of the above

Answer 1

The interface of a 'black box' is accurately described as the way it connects with the external world, typically through names and parameters of subroutines or functions.

Step-by-step explanation:

The question asks which statement describes the interface of a "black box" in the context of computing and software. The correct answer is: a. The interface of a black box is its connection with the rest of the world, such as the name and parameters of a subroutine. This explanation captures the essence of what an interface is in software design. An interface defines how different components of a program, such as functions or modules, interact with each other without exposing the underlying implementation details. It serves as a contract that specifies what the inputs and outputs are for a given operation, allowing different components to interoperate seamlessly.

In contrast, the implementation refers to the internal workings or the actual code that fulfills the contract specified by the interface. It handles the complex logic behind the scenes and can be changed without affecting other parts of the system, as long as the interface remains consistent. Hence, options b and c are incorrect as they do not accurately describe the interface.
