ServerSocket represents the socket on a server that waits and listens for service 
from a client. Socket represents the endpoints for communication between a server 
and a client. When a server gets a request for service, it creates a Socket for 
communication with the client and continues to listen for other requests on the 
ServerSocket. The client also creates a Socket for communication with the 
server.
