WebSocket: Real-time Communication Protocol for Web Applications

WebSocket is a computer communication protocol that enables two-way communication between a client and a server over a single, long-lived connection. It allows for real-time data transfer and eliminates the need for the client to constantly poll the server for updates. WebSocket is commonly used in web applications for real-time chat, gaming, and collaborative editing. It is supported by most modern web browsers and can be implemented using several programming languages including JavaScript, Python, and Java.
