sockets

Ein Protokoll für bidirektionale Echtzeitkommunikation zwischen Client und Server.

WebSocket unterscheidet sich von HTTP. Während HTTP auf Anfrage-Antwort basiert, ermöglicht WebSocket eine dauerhafte Verbindung in beide Richtungen. Ideal für Chats, Spiele, Live-Ticker.

A socket is like an electrical outlet for data. If you want your vacuum cleaner (your program) to work, you have to plug it into the wall (the socket). One end is on your computer, and the other end is on the server you are talking to.

🤓 Expert Deep Dive

Unix Sockets provide high-performance IPC on the same host, while Network Sockets (INET) use the TCP/IP stack. The 'Berkeley Sockets' API is the de-facto standard. Socket options like SO_REUSEADDR and TCP_NODELAY allow developers to fine-tune network behavior for performance and latency.
