Connecting devices to exchange information is what networking is all about.

Sockets are an essential part of effective network communication. They are the underlying concept used to transmit messages between devices over local or global networks and between different processes on the same machine.

They provide a low-level interface that allows for fine-grained control over the traffic that is to be sent or received.

This is what makes sockets exceptionally useful in real-time client-server applications that depend on instant message exchange or operate with huge amounts of data.

Socket 是網絡通信的重要組成。用於網絡上設備之間或同一台機器上的不同程式之間傳遞消息。

Socket提供了接口，允許對流量進行控制。

Socket常用於即時的客戶端-伺服器應用程序，這些應用程序依賴於即時消息交換或處理大量數據。
