WebSocket is a communication protocol that enables real-time two-way data transfer between a client and a server. Unlike HTTP, which is a request/response protocol, WebSocket is a persistent connection that allows bi-directional data exchange in real-time without the need for the client to initiate a new request for each exchange.WebSocket is particularly useful for applications that require real-time updates and low latency, such as online gaming, real-time financial data, and chat applications. It allows for efficient and fast communication between a client and a server, reducing latency and providing a better user experience.WebSocket uses a handshake process to establish a connection between the client and server. Once the connection is established, the server can push data to the client at any time, and the client can send data back to the server without the need for a new request/response cycle. WebSocket uses a binary or text-based data format for data transfer, depending on the application requirements.
