Interfaces have applications in many fields, including electronics, computer hardware, software programming, and so on, with a variety of roles.

In the field of hardware, interfaces are mainly used to connect external devices or for data transmission. For

example, USB, HDMI, SATA, RJ45, etc., are different types of I/O interfaces, which have address recognition,

address decoding, buffering, temporary storage, drive capabilities and other functions of the host and I/O devices

to meet specific load and timing requirements. The interface can also achieve host and peripheral format compatibility,

level conversion, digital signal and analog signal conversion, transmission mode conversion and other functions.

In the field of software programming, the role of interfaces is mainly reflected in the following aspects:

Definition specification: An interface defines the specification of a certain function. When a new function needs to be

extended, the new function specification is defined in the interface. The subclass only needs to implement the interface,

so it knows what functions need to be rewritten and what new functions need to be added, thus avoiding the randomness of the subclass coding.
Improve development efficiency: Interfaces can separate projects, and all layers are oriented towards interface

development, thus improving development efficiency.
Reduce coupling degree: The interface reduces the coupling degree between code and code, becomes pluggable,

and can be switched at will, thereby improving the flexibility and maintainability of the code.
Combination and extension of implementation classes: A class can implement multiple interfaces and thus have the

functionality defined by multiple interfaces. This combination and extension of classes through interfaces can make the functions of classes richer and more flexible.
Inheritance and extension: Interfaces can inherit and extend each other, and an interface can inherit one or more interfaces, thereby extending the function of the interface.
In summary, interfaces play a crucial role in both hardware and software fields, and are important tools for connecting, extending, and standardizing functions.
