In any network diagram, the router is the central node. Its primary job is to connect different networks, typically linking a local area network (LAN) to the broader internet (WAN). In a diagram, it is usually represented by a circular icon with four arrows pointing inward and outward, symbolizing its function: receiving data packets and directing them to their correct destination based on IP addresses.

Network diagrams generally fall into two categories. show the actual hardware and the literal cables (Ethernet, fiber optic) connecting them. These are invaluable for technicians who need to physically troubleshoot a server room. Logical diagrams , on the other hand, focus on the flow of data. They detail IP addresses, subnets, and VLANs, providing a high-level view of how information moves through the router without worrying about which port a cable is plugged into.
