This is a low-level data transfer mechanism that exists in parallel with the classes of the higher-level I/O library (packages java.io and java.net). A channel implementation can be obtained from a high-level data transfer class such as java.io.File, java.net.ServerSocket, or java.net.Socket, and vice versa.
Socket.IO is an event-driven library for real-time web applications. It enables real-time, bi-directional communication between web clients and servers. [ 3 ] It consists of two components: a client , and a server .

[citation needed] A socket is typically set to blocking or non-blocking mode using the functions fcntl ...

Rhino converts JavaScript scripts into classes. Rhino works in both compiled and interpreted mode. It is intended to be used in desktop or server-side applications, hence there is no built-in support for the Web browser objects that are commonly associated with JavaScript.
JavaScript asynchronous, event-based I/O. Influenced by systems like Ruby's Event Machine, Perl's POE or Python's Twisted. Plenty of modules available. Opera: Futhark: Opera Unite JavaScript is the server-side language used to develop services for the Opera Unite feature of the Opera browser. This is a server built into the browser.
