Description: High coupling is a situation where classes or components of a system heavily depend on each other, making maintenance and scalability difficult. In software development, coupling refers to how different parts of a program are interconnected. High coupling implies that a change in one class may require changes in many others, leading to increased time and effort needed for modifications or corrections. The main characteristics of high coupling include difficulty in performing unit tests, reduced code reuse, and complexity in understanding the system as a whole. In contrast, low coupling is desirable as it allows components to function more independently, facilitating software maintenance and evolution. The relevance of high coupling lies in its direct impact on software quality; systems with high coupling tend to be more fragile and less adaptable to future changes, which can result in increased costs and development times.
