Websockets

WebSockets: A protocol for full-duplex communication between client and server over a single persistent connection.

Difference:

• HTTP: Request-response model; client initiates every interaction.
• WebSockets: Persistent, allowing real-time, two-way communication (e.g., live chat, notifications).

Example:

• HTTP: Send a request for new messages repeatedly (polling).
• WebSocket: Server pushes new messages as they arrive.
