💡 Hint

Common Mistakes

Confusing HLD with detailed coding tasks.

Thinking HLD includes unit test details.

HLD (High-Level Design) focuses on the overall architecture of the system, showing components and their interactions.

💡 Hint

Common Mistakes

Mixing LLD with overall system architecture.

Assuming LLD covers user interface design only.

LLD (Low-Level Design) focuses on detailed design of components, including algorithms and data structures.

💡 Hint

Common Mistakes

Thinking HLD covers detailed class design.

Confusing detailed design with architecture.

HLD does not include detailed design like class methods; that belongs to LLD.

💡 Hint

Common Mistakes

Mixing user interactions with design levels.

Confusing hardware details with software design.

HLD shows system components and their relationships, while LLD shows the code structure inside those components.

5fill in blank

hard

Fill all three blanks to complete the design process steps.

HLD

First, create [1] to outline the system. Then, develop [2] for modules. Finally, write [3] to implement features.

💡 Hint

Common Mistakes

Reversing the order of design steps.

Confusing test cases with design phases.

The design process starts with HLD to outline the system, then LLD for module details, and finally code implementation.
