The root server can only resolve id labels, and only returns the associated name server. The client will pass the rest of the path name (ie id : [ac, del]) to the name server. The name resolver client then contacts the next name server, which responds by resolving the ac label and returning the del server address. The concept is what resolution?

When the root name server finds the address of the name server that implements the id node, the root name server asks the server to resolve the path name id : [ac, del].
