And we as the server actually only use the bind when this port, the port number 65535 is not the limit of concurrency.Server maximum number of TCP connections: server is usually fixed on a local port for listening, waiting for client connection requests. Regardless of address reuse (Unix's so_reuseaddr option), the local listener port is exclusive even if there are multiple I

Because Linux can be started without a graphical interface, thus saving resources (of course, Linux also has a graphical interface), but also free of charge, such as the enterprise-class CentOS Linux system, but CentOS has recently been acquired by RH, but still have a community-driven version.That's the only reason why Linux is a pure rip-off like Windows security-resistant.Now as a developer choose Ubuntu Good.Why do servers use Linux??
