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. The Dispatcher must also establish client data areas, as well as client registration before the spawn.
After the Dispatcher is finished, the unique thread started for each client will execute concurrently with other threads in the system. It is here that modifications for thread pooling could be made if resources were being overused.
