Question

Accepted Answer

HLD stands for High Level Design and LLD stands for Low Level Design. HLD focuses on overall system design while LLD focuses on detailed design.

HLD involves defining system architecture, modules, interfaces, and high-level design decisions.
LLD involves detailed design of each module, including data structures, algorithms, and specific implementation details.
HLD is more abstract and focuses on the big picture, while LLD is more concrete and detailed.
Example: In a software project, HLD may outline the overall system architecture using UML diagrams, while LLD may specify the classes and methods in each module.
