Network Operations

The actual hardware and cabling — devices, ports, cable runs, and where equipment physically sits in rooms and racks.

How data flows through the network — IP addressing, subnets, VLANs, and routing relationships — independent of physical cabling.

A physical diagram (or cable map) — it documents actual cable runs and port connections; a logical diagram only shows addressing and data flow.

The physical layer: cable types and runs, patch panels, ports, and physical device connections.

Data link layer relationships: switches, VLAN assignments, trunk links, and MAC-level topology.

Network layer design: routers, IP subnets, routing protocols, and gateways showing how traffic is routed between networks.
