This diagram shows a network topology that includes a router, two workstations, an access point, a printer, and two workstations connected through a switch. In the network topology, the router acts as a central node that connects different network segments together for data transmission and sharing. The two workstations are on different network segments and can be connected to the Internet through the router for remote access and data transfer. This type of diagram allows engineers to understand the different elements of any given network and what one can expect from their communication performances.
