A circuit package includes first and second units containing functional circuitry. In response to determining that a request for information received from a client is non-optimal in terms of processing the request, a first hint can be constructed that indicates how future requests are to be formulated by the client so that they are more optimal in terms of processing the future requests. The carrier has a first surface and a second surface. Users can navigate the SKB in search of a solution to a problem with the device with the assistance of the virtual representation which enables actuation of the existing links.
