Frequently asked questions about network diagrams

Network diagram symbols are shapes and icons used to represent different components in a computer or telecommunications network, such as routers, switches, databases, and devices like PCs and telephones.

Lucidchart provides shape libraries for AWS, Azure, Google Cloud, Cisco, and generic network diagram symbols and icons.

Router symbols represent devices that manage traffic between devices or networks and can facilitate wireless access points or broadband modems.

Switch symbols represent multiple Ethernet ports that enable connection of multiple devices, while bridge symbols connect two Ethernet networks into one larger extended network, especially useful for geographically separated networks.

Connector shapes show the path that data travels within your network, with different connection symbols used depending on the type of traffic being routed.

Yes, you can import SVGs and other image files to create your own network diagram symbols if you can't find what you need in Lucidchart's libraries.

Open a new Lucidchart document, press the "+ Shapes" button on the left of your screen, and enable all the relevant shape libraries.

Database shapes can be chosen based on your needs, including operational, specific, external, or hypermedia databases, as well as by supporting machine type or query language.
