The term WebSocket refers to a TCP communications protocol over ws:// or the secure and encrypted wss://. It's different from HTTP, although it can run over port 80 or 443 to ensure it works in places which block non-web traffic.
Long polling Ajax techniques can make web apps seemingly update in real time, but the process is too limiting for true real-time applications.
