📚 Quick Study Guide: Client-Server Architecture

🖥️ Client-Server Model: A distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.
🌐 Client: Typically a user's device (e.g., web browser, mobile app) that requests resources or services from a server.
💾 Server: A powerful computer or program that provides resources, data, services, or programs to other computers (clients) over a network.
📡 Communication: Clients send requests to servers, and servers send responses back to clients. This often happens over a network like the internet.
💡 Key Benefits: Centralized data management, enhanced security, ease of maintenance, and scalability.
🛡️ Examples: Web browsing (browser-web server), email (email client-email server), online banking, cloud storage, gaming, DNS.
🔄 Request-Response Cycle: The fundamental interaction where a client initiates a request and waits for a server to respond.
