low-level design

Low-level design (LLD) is a detailed blueprint for building software, focusing on how individual components and modules work and interact. It involves specifying the exact functions, data structures, algorithms, and logic needed for each part of the system. Think of it as translating a high-level plan into precise instructions that developers follow to create the software's building blocks, ensuring each piece functions correctly and integrates smoothly with others. LLD helps ensure the system is efficient, maintainable, and bug-free by providing clarity about the internal workings of each component.
