What does modularity mean?

Modularization refers to the process of dividing the system into several modules layer by layer from top to bottom when solving a complex problem. It has a variety of attributes that reflect its internal characteristics. The function of modularization is to divide, organize and package software; each module completes a specific sub-function, and all modules are assembled in a certain way to become a whole and complete the functions required by the entire system.

Function

Modularization is used to divide, organize and package software. Each module completes a specific sub-function, and all modules are assembled in a certain way to form a whole to complete the functions required by the entire system.

The module has the following basic attributes: interface, function, logic, and status. The function, status, and interface reflect the external characteristics of the module, and the logic reflects its internal characteristics.

In the structure of the system, modules are units that can be combined, decomposed and replaced. Modularization is a way of dealing with the decomposition of complex systems into better manageable modules. It can handle complex and large-scale software by setting different functions in different components and decomposing a problem into multiple small, independent, interacting components.

Operation mode

1. Independent working operation mode

Each module can work independently. Even if a single group of modules fails, the entire system will not be affected. Work.

2. Hierarchical startup function

When each group of modules reaches full load, the system will automatically start another group of modules, thereby ensuring that the output of the system always matches the actual demand and ensuring that each module is efficient operation, it can save resources and improve efficiency.

Modular Programming

Software module is a set of consistent and closely related software organizations. It contains two parts: program and data structure respectively.

Modern software development often uses modules as units of synthesis.

The interface of a module expresses the functionality provided by the module and the elements required to call it.

Modules are units that may be written separately. This makes them reusable and allows a wide range of people to collaborate, write and work on different modules simultaneously.
