Definition
WebSocket is a computer communications protocol that enables persistent, two-way communication between a client and a server. Unlike HTTP, which requires a new connection for each request-response cycle, WebSocket maintains an open connection, allowing data to be sent back and forth instantly. This makes it ideal for applications requiring low latency and high frequency updates, such as live gaming, financial trading platforms, and collaborative editing tools, significantly reducing overhead compared to polling methods.
