Summary

WebSockets provide a protocol for maintaining a persistent, low-latency connection between a client and server, facilitating bidirectional data exchange without requiring repeated requests. This capability makes WebSockets ideal for real-time applications like games, chat apps, financial trading, and IoT data communication. In a tutorial, users learn to create a WebSocket server using Node.js and the 'ws' library, while employing Postman to send and receive messages across the connection. By setting up a local server, users can send CPU load data every second using the 'systeminformation' package and explore modifications such as adjusting message intervals and customizing data sent. The tutorial encourages further exploration of WebSockets in IoT applications and offers additional resources for deeper learning.
