Tightly coupled systems refer to a type of system architecture where the components or modules are highly dependent on each other.

In other words, changes made to one component can have a direct impact on other components within the system.

This close interconnection between components can lead to potential issues such as difficulty in making changes, lack of flexibility, and increased complexity. Tightly coupled systems are often characterized by strong dependencies between components, making it challenging to isolate and modify individual parts without affecting the entire system.

As a result, any changes or updates to one component may require corresponding changes to multiple other components, leading to a domino effect of modifications. These systems are typically more difficult to maintain and scale, as any modifications or enhancements can have far-reaching consequences throughout the system.

In addition, tightly coupled systems can be more prone to errors and bugs, as changes in one component may inadvertently impact the functionality of other components. Despite the drawbacks of tightly coupled systems, they are sometimes necessary in certain situations where performance or efficiency is prioritized over flexibility or modifiability.

However, it is important for developers to carefully consider the trade-offs and potential implications of using a tightly coupled system, and to weigh the benefits against the drawbacks before implementing such an architecture. In conclusion, tightly coupled systems are a type of system architecture where components are closely interconnected, leading to strong dependencies and potential challenges in maintenance and scalability.

While these systems may offer certain advantages in terms of performance, developers should carefully consider the implications of using a tightly coupled architecture and weigh the trade-offs before proceeding with implementation.
