Network diagrams illustrate the relationships between computers, peripheral devices, and computer systems.
The Different Types of Network Diagrams
SmartDraw allows you to draw both vendor specific and conceptual or generic diagrams.

Vendor Specific

Conceptual or Generic
Basic Network Design Topology
Topology refers to the geometric arrangement of devices on a network. Local Area Networks (LANs) appear in one of three topologies: linear, ring, or star. Larger networks can be a combination of two or more of these.
Bus, linear, Ethernet, or backbone topology

Token ring topology

Star topology

Networking Design Symbols
Network diagrams can contain both generic and vendor specific devices. There are too many devices to illustrate here, but some of the basic shapes are represented below.
Cloud shape - used to represent segments of the network or internet where details are not important

Work stations, clients, or nodes

Servers

Mainframes

Connection devices: hubs, routers, switches, gateways, and bridges

Peripheral Devices
