socket编程问题

Question

//客户端
Socket socket = new Socket(InetAddress.getLocalHost(), 9999);
 System.out.println(socket);
//输出Socket[addr=localhost/127.0.0.1,port=9999,localport=60635]

//服务端
 ServerSocket serverSocket = new ServerSocket(9999);
 Socket socket = serverSocket.accept();
 System.out.println(socket);
//输出Socket[addr=/127.0.0.1,port=60635,localport=9999]

请问这两个socket算是一样的吗？socket是两根绳子连接，还是通过一个绳子连接两边的端口
