Couplers in programming refer to the degree of interconnectedness or interdependence between different components of a software system. High coupling, or strong coupling, refers to a system in which components are closely connected and rely heavily on each other. This can make the system more difficult to understand, maintain, and modify, as changes to one component may have unintended consequences on other components.

On the other hand, low coupling, or weak coupling, refers to a system in which components are more independent and have fewer dependencies on each other. This can make the system more modular and easier to understand, maintain, and modify, as changes to one component are less likely to affect other components.

There are several ways in which coupling can be reduced in a software system:

1. Use of design patterns: Design patterns, such as the Model-View-Controller (MVC) pattern, can help to decouple components and reduce their dependencies on each other.
2. Use of interfaces: Interfaces can be used to define the contracts that different components must follow, allowing them to communicate with each other without being directly connected.
3. Use of dependency injection: Dependency injection is a technique in which components are provided with their dependencies at runtime, rather than being hard-coded. This can help to reduce coupling and make the system more flexible.

By reducing coupling in a software system, developers can create software that is more modular, maintainable, and scalable. It is important to carefully consider the relationships between different components when designing and implementing a software system in order to achieve low coupling and the benefits that it brings.
