Define what is Dispatcher
In the Worker Model, it is the task of the Dispatcher to spawn a thread for every client-to-server connection. The Dispatcher acts as the go-between of the SCM and the Executor. Its main function is to provide initiation (or dispatch) threads to execute on behalf of the client.
