API, REST API & WebSocket API Explained | IoT Communication Made Easy

Learn the concepts of API, REST API, and WebSocket API in a simple and easy-to-understand way. This video explains how an API acts as a bridge between client and server, how REST API uses a request-response model with stateless communication, and how WebSocket API provides continuous full-duplex two-way communication over a persistent connection. You’ll also understand these concepts through practical examples such as mobile apps, servers, databases, temperature sensors, cloud servers, and live monitoring dashboards. Useful for ECE, AIML, CSE, BTech and college students studying IoT, networking, APIs, and communication models. 📚 Watch the Complete IoT Playlist: 🔗    • Internet of Things   #API #RESTAPI #WebSocket #IoT #IoTCommunication
