A router helps determine the shortest path for networks. Hosts from different logical networks can be in a position to communicate with one another. It can also be applied in the case of two networks as a gateway of connecting other networks. It is therefore crucial for Lisa to use the router considering the prevailing circumstances. If however, the networks are on the same practical line, it would be unnecessary to use a router.
A viable option to act upon, as proposed by Jennifer, is using a bridge. A bridge allows only available known networks to get connected. It does not incorporate OIS model in its layer hence unable to distinguish networks. Thus, a bridge should be applied in the event Sampson uses similar networks within its premises. In addition, it does not recognize communication protocol rather allows media to access physical means such as IP address and media access control (MCA) respectively.
