WebSocket
networkingA communication protocol providing full-duplex channels over a single TCP connection
Pronunciation
Correct
WEB-sock-it
/ˈwɛb ˌsɒkɪt/
Pronounced as two words: 'web' and 'socket'. RFC 6455 defines the WebSocket protocol and the IETF documentation uses this natural compound word pronunciation.
