Socket programming is the process that builds a communication channel between the server and the client using sockets. In the following example code, the client starts a contact with the server, and the server is set up to accept the client connections. Let us understand the server and client...
端系统也叫主机,通过通信链路(communication link)和分组交换机(packet switch)连接到一起。市面上流行着各种类型、各具特色的分组交换机,两种最有名的类型是路由器(router和链路层交换机(link-layer switch)。 端系统通过因特网服务提供商(Internet Service Provider,ISP)接入因特网,包括如 本地电缆或电话公司那样...

Socket.IO is a library that enableslow-latency,bidirectionalandevent-basedcommunication between a client and a server. It is built on top of theWebSocketprotocol and provides additional guarantees like fallback to HTTP long-polling or automatic reconnection. ...
In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create severalNamespaces, which will act as separate communication channels but will share the same underlying connection....
