WebSocket is a communication protocol that enables real-time, bidirectional communication between a client and a server. Unlike HTTP, which is request-response based, WebSocket allows the server to push data to the client without waiting for a request.

WebSocket is used in full-stack development for applications that require real-time updates, such as chat applications, live notifications, or online gaming. For example, a React frontend can establish a WebSocket connection with a Django backend to receive live updates.

In Python, libraries like channels (for Django) and websockets (for Flask) make it easy to implement WebSocket functionality. This enables developers to build interactive and responsive applications that provide a better user experience.
