🌟 Polling and long-polling vs WebSockets vs Server-Sent Events (SSE)🌟 🔶WebSockets: Provides a persistent, full-duplex connection between the client and server. 🔶Server-Sent Events (SSE): Allows servers to push updates to the client over a single HTTP connection. 🔶Polling: Polling is a technique where the client regularly sends requests to the server to check for updates or new data. 🔶Long-Polling: Long-polling is an enhanced version of polling designed to reduce latency and resource usage. It keeps a connection open until the server has new information to send. Client-server communication is a fundamental aspect of networked applications where two main entities are involved: the client and the server. Understanding client-server communication is important for designing and implementing effective and efficient network applications like flight booking applications EaseMyTrip.com , Booking.com and stock market applications 5paisa , Upstox ). 🌟 Here's an overvi...
