What Is Modular Designing ?

 Definition :   Modular design, or modularity in design, is a design principle that subdivides a system into smaller parts called modules , which can be independently created, modified, replaced, or exchanged with other modules or between different systems.

    Modular design in computer hardware is the same as in other things . The idea is to build computers with easily replaceable parts that use standardized interfaces. This technique allows a user to upgrade certain aspects of the computer easily without having to buy another computer altogether.

     A computer is one of the best examples of modular design. Typical computer modules include power supply units, processors, mainboards, graphics cards, hard drives, and optical drives. All of these parts should be easily interchangeable as long as the user uses parts that support the same standard interface. Similar to the computer's modularity, other tools have been developed to leverage modular design, such as littleBits Electronics, which snap together with interoperable modules to create circuits.

    For smartphones, this idea was explored in Project Ara, which provided a platform for manufactures to create modules for a smartphone which could then be customised by the end user. The Fairphone uses a similar principle, where the user can purchase individual parts to repair or upgrade the phone.
