This image shows a network topology designed in Cisco Packet Tracer.

The network is divided into multiple VLANs/subnets, and each colored section represents a different department or group of devices. PCs, laptops, printers, access points, and servers are connected to switches, while the routers in the center provide communication between the different networks. This design helps organize the network, improve security, and allow efficient data sharing between all connected devices.
