Modular design is a process of dividing a system into smaller parts or modules, which can be subsequently interconnected to form a larger system or product. There are numerous synonyms for modular design, which can be used interchangeably depending on the context. Some common synonyms include component-based design, building block design, object-oriented design, and system architecture. Other synonyms that can be used include block design, section design or piece design. The primary goal of creating a modular design is to improve flexibility, scalability, and efficiency in systems or products. With a modular design, it is easier to reconfigure the system, replace faulty components, and make future modifications or upgrades.
