Node is designed to build scalable network applications in the following hello world example many connections can be handled concurrently.Upon each connection the callback is fired but if there is no work to be done Node will sleep.Thread-based networking is relatively inefficient and very difficult to use.Furthermore users of Nodejs are free from worries of dead-locking the process since there are no locks.Almost no function in the app directly performs io so the process never blocks. Because nothing blocks scalable systems are very reasonable to develop in Node the systems like Rubys Event Machine or Pythons Twisted it takes the event model a bit further.
Nodejs is designed without threads does not mean you cannot take advantage of multiple cores in your environment Child processes can be spawned by using child process api and are designed to be easy to communicate with.Built upon that same interface is the cluster module which allows you to share sockets between processes to enable load balancing over your cores.It presents an event loop as a runtime construct instead of as a library in other systems there is always a blocking call to start the event loop.Typically behavior is defined through callbacks at the beginning of a script and at the end starts a server through a blocking call like EventMachine.In Node js there is no such start the event loop call it simply enters the event loop after executing the input script the tool exits the event loop when there are no more callbacks to perform.
Node can be installed in multiple ways on a computer the approach used by you depends on the existing development environment in the system.There are different package installer for different environments you can install Node by grabbing a copy of the source code and compiling the application.The development of scalable applications that are especially tailored for network environments and meant to be deployed on interconnected devices is a complex endeavor.One which is reserved for professionals and expert users who have at their disposal the appropriate tools for the job.Built upon that same interface is the cluster module which allows you to share sockets between processes to enable load balancing over your cores.It presents an event loop as a runtime construct instead of as a library In other systems there is always a blocking call to start the event loop.
