Xiaobian to share with you what the plug-in refers to in the computer, I hope you have gained something after reading this article, let's discuss it together!

A plug-in is a program written in accordance with a specified application program interface. It can only run on the system platform specified by the program (it may support multiple platforms at the same time), and cannot run independently from the specified platform.

Operating environment of this tutorial: Windows 10 system, Dell G3 computer.

Plug-in (also known as addin, add-in, addon or add-on) is a program written in accordance with a certain specification of the application program interface. It can only run under the system platform specified by the program (it may support multiple platforms at the same time), and cannot run independently from the specified platform. Because plug-ins need to call the original pure system to provide the library or data. A lot of software has plug-ins, plug-ins there are countless kinds. For example, in IE, after installing the relevant plug-in, the WEB browser can directly call the plug-in program for processing specific types of files.

Plug-ins date back to the mid-1970s, when EDT text editors ran Unisys VS/9 on Univac90/60 series mainframes, providing the ability for the editor to run a program and allow that program to enter the editor buffer, allowing external programs to access the task being edited in memory. Plug-ins enable the editor to edit text in a buffer that is shared by the editor and plug-ins. The Waterloo Fortran compiler uses these features to make the internal compilation of Fortran programs editable with EDT.

The benefits of plug-in technology

Using plug-in technology can bring benefits in analysis, design, development, project planning, collaborative production, and product extension:

(1) The structure is clear and easy to understand. Because of the reference to the hardware bus structure, and each plug-in is independent of each other, so the structure is very clear and easier to understand.

(2) Easy to modify and maintainable. Because plug-ins are connected to host programs through interfaces, like hardware plug-ins, they can be deleted, inserted and modified at any time, so the structure is flexible and easy to modify, facilitating software upgrades and maintenance.

(3) Strong portability and reuse. Because plug-ins themselves are composed of a series of small functional structures, and provide their own services to the outside through interfaces, reuse efforts are greater and porting is more convenient.

(4) The structure is easy to adjust. The increase or decrease of system functions only needs to add or delete plug-ins accordingly, without affecting the whole architecture, so it is convenient to realize structural adjustment.

(5) The coupling degree between plug-ins is low. Because plug-ins communicate with host programs to implement plug-in-plug-in, plug-in-host communication, so the degree of coupling between plug-ins is lower.

(6) Applications can be modified during software development. Due to the adoption of plug-in structure, plug-ins can be modified at any time during the development process of software, and plug-ins can also be added and deleted in the form of patch packages after the application is released, so as to achieve the purpose of modifying the application program through this form.

(7) Flexible and changeable software development methods. You can adjust the development method according to the actual situation of resources. If you have sufficient resources, you can develop all plug-ins. If you don't have sufficient resources, you can choose to develop some plug-ins. You can also ask third-party manufacturers to develop them. Users can also develop according to their own needs.
