Modular systems are designs made up of separate, interchangeable components or modules. Each module can function independently or work together with others, allowing for flexibility and customization. This approach is commonly used in various fields, including software development, architecture, and manufacturing, enabling easier upgrades and repairs. The benefits of modular systems include reduced complexity and improved efficiency. By breaking down a larger system into smaller parts, it becomes simpler to manage and modify. This can lead to cost savings and faster production times, as well as the ability to adapt to changing needs or technologies over time.
