What is a key advantage of using modular design in signal networks?

A key advantage of using modular design in signal networks is that it supports adaptation to new technologies and needs. Modular design allows for the integration of new components and systems without the need for a complete overhaul of the existing network. This flexibility is crucial in modern signal environments where technology is constantly evolving. By utilizing a modular approach, organizations can easily update or replace specific modules as new technologies emerge, ensuring that their operations remain efficient and effective. Additionally, this adaptability helps in addressing changing operational requirements or challenges, enhancing the network's overall resilience and longevity.

In contrast, the other options do not accurately capture the benefits of modular design. While maintenance procedures may become simpler due to modularity, that is only one aspect and does not encompass the broader advantages of adaptability and technological integration. Complete rigidity is contrary to the principle of modularity, which emphasizes flexibility and ease of modification. Furthermore, reducing overall network effectiveness is not a characteristic of a well-implemented modular design; instead, such a design is intended to enhance network performance and effectiveness by allowing for ongoing improvements and adjustments.
