sockets

클라이언트와 서버 간의 실시간 양방향 통신을 위한 프로토콜입니다.

웹소켓은 HTTP와 다릅니다. HTTP는 요청-응답 기반이지만, 웹소켓은 데이터가 양방향으로 동시에 흐를 수 있는 지속적인 연결을 가능하게 합니다. 채팅, 게임, 실시간 업데이트가 필요한 앱에 이상적입니다.

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.
