WebSockets is a communication protocol that enables real-time, two-way interaction between a client and a server over the internet. Unlike traditional HTTP requests, which require a new connection for each interaction, WebSockets maintain a single, persistent connection. This allows for faster data exchange and is particularly useful for applications like online gaming, chat applications, and live notifications. The protocol works by establishing a handshake between the client and server, after which they can send messages to each other freely. This efficient communication method reduces latency and bandwidth usage, making it ideal for scenarios where timely data updates are crucial.
