Answer:
In system design, modular design is technique used to divide a system in smaller parts to modify, create or change it easily.
Step-by-step explanation:
There are many example of modular design, few of them discussed here.
1. Computer system:
First basic example to understand the modular design is a computer system, a computer system is the composition of different parts such as Monitor, CPU, Key board, mouse and Speakers. All these parts are available separately and combined to complete a computer system.
2. Modular Programming
In modular programming, a program is subdivided into smaller portions that make it easy to modify, test and reused in other portions of the program.
