In what type of coupling the complete data structure is passed from one module to another?

OverviewIn this shot, we’ll be discussing the importance of coupling & cohesion in software engineering. But before moving into this topic, we should know what modularization is so we can grasp the concept of coupling easily. ModularizationModularization is the process of breaking a software into multiple small modules, where each module works independently. The main advantage of modularization is that it makes it easy to understand the software, makes it reusable, and it can be tested easily. What is coupling in software engineering?Coupling is the inter-dependency or degree of relationship between multiple modules/packages/components. Coupling is also called Inter-module Binding. Multiple modules/packages/components that are highly coupled are strongly dependent on each other. Multiple modules/packages/components that are loosely coupled are not or somehow dependent on each other.
The higher the number of calls between modules, the more error prone it will be. For low-coupled classes, changing something major in one class should not affect the other. High coupling would make it difficult to change and maintain your code. Types of coupling
There is another concept that is used with coupling known as cohesion. What is cohesion in Software engineering?Cohesion refers to what a module can do, internally. It is also called Intra-Module binding as it measures the strength of the relationship of functionalities inside a module/package/component. Cohesion should always be high means that a module/package/component is focused on what it should be doing, such as only methods relating to the intention of the class. Example of low cohesion:
Example of high cohesion:
In the above example, we see that the Types of cohesion
CONTRIBUTOR Mohammad QuanitWhich type of coupling coupling exists between two modules if data from one module is used to direct the order of instruction execution in another?4. Control Coupling: Control Coupling exists among two modules if data from one module is used to direct the structure of instruction execution in another.
Which of the following is the type of module coupling?Which of the following is the best type of module coupling? Explanation: The dependency between module A and B is said to be data coupled if their dependency is based on the fact they communicate by only passing of data. 5.
Which coupling is the type of coupling between modules when a control switch is passed as an argument?C. D. Explanation: two modules are control coupled if one passes an element of control to another.
What is coupling name two types of coupling?Couplings fall into two main categories: Material Flexing and Mechanical Flexing.
