WebSocket

WebSockets are like a two way tunnel between a computer and a website. Think of it like a phone line. You can call someone on the other end and they can call you back too.

In the same way, when you connect to a website using WebSockets, your computer can send messages to the website and the website can send messages back. The website can use this to get updates from your computer and send new information to you without having to reload the page.
