Multiple Choice Questions on Client-Server Communication

📚 Quick Study Guide: Client-Server Communication Essentials

• 🌐 Client: An application or system that initiates requests for services or resources from a server. It typically interacts with users and displays information.
• 🖥️ Server: A program or device that provides functionality or data to other programs or devices (clients) over a network. It listens for requests and responds with the requested resources or services.
• 🔄 Request-Response Model: The fundamental interaction pattern where a client sends a request to a server, and the server processes it, then sends a response back to the client.
• 🔗 Protocols: Standardized rules that govern how data is transmitted between client and server. Common examples include HTTP (web), FTP (file transfer), SMTP (email), and DNS (domain name resolution).
• 📡 Network: The medium (wired or wireless) connecting clients and servers, allowing them to exchange data.
• 🛡️ Stateless vs. Stateful:
  • 📝 Stateless: Each request from a client to a server is treated as an independent transaction. The server does not store any client-specific session information between requests (e.g., HTTP).
  • 🧠 Stateful: The server maintains information about the client's session over multiple requests, remembering past interactions (e.g., FTP, online shopping carts).
• ⚙️ Ports: Numerical endpoints used by network protocols to identify specific applications or services on a server (e.g., HTTP uses port 80, HTTPS uses 443).
