  Basics of Thick Client .Net,  C Sharp,  Static and Dynamic Analysis. 2-Tier Architecture vs 3-Tier Architecture These are both types of software architecture models used for building client-server applications. Here's a comparison: 🔹 2-Tier Architecture Structure: Client (Presentation Layer) Server (Data Layer + Business Logic) Diagram: Client  <-->  Server (DB + Logic) Explanation: The client directly communicates with the server. The server handles both the database operations and the business logic . Example: A desktop app accessing a database server directly. Pros: Simpler and faster to develop Fewer layers = less complexity Cons: Harder to scale Tight coupling between client and server Poor maintainability 🔹 3-Tier Architecture Structure: Presentation Layer (Client/UI) Application Layer (Business Logic) Data Layer (Database Server) Client  <-->  Application Server  <-->...
