What are the three components of system design?

The three primary components of system design are:

1. Frontend (Client-Side)

The frontend is the part of the system that users interact with directly, usually through web or mobile interfaces. It involves:

• User interface (UI) design
• User experience (UX) optimization
• Handling user input and interacting with the backend via APIs

2. Backend (Server-Side)

The backend consists of the server-side components that process requests, handle business logic, and interact with the database. Key elements include:

• Application servers: Execute the core business logic.
• APIs: Facilitate communication between the frontend and backend.
• Databases: Store and retrieve data efficiently.
