What is a Network Diagram?

A network diagram is a visual representation of network architecture. It maps out the structure of a network with a variety of different symbols and line connections. It is the ideal way to share the layout of a network because the visual presentation makes it easier for users to understand how items are connected.

Network Diagram Symbols

A network diagram may include hundreds of different symbols. They can range from a PC to a complex server rack to a cloud-based storage system. The symbols may be brand-specific, generic, or a combination. The network diagramming tools in SmartDraw allow users to modify existing symbols to create a custom library of symbols for their own organization or its customers.

Types and Uses of Network Diagrams

A network diagram demonstrates how one computer or system is affiliated with others. This is especially useful when trying to track down problems or when designing a new system. Often the root of a problem can be traced more easily by observing and analyzing how the computers and components in the system are connected.

How to Draw a Network Diagram

There are many different ways to create a network diagram. While they can be created using pen and paper or a white board, a diagramming tool designed for this purpose is a much more efficient and effective approach.

You can drag and drop shapes of network components and connect them with lines to illustrate connections easily. Read SmartDraw's network diagram tutorial.

Consider these tips:

  • Choose a network: Select the network to illustrate. The diagram could focus on a personal computer, or on an entire company network. Once a focus has been chosen, set limits on what outside connections will be included so that the diagram remains concise.
  • Add relevant equipment: Begin by placing any involved computers, servers, and other components on the page. Use visual representations and add the names of the components for clarity.
  • Add any other important components: Add other important components such as internet connections and firewalls. Once again, use visual representations and add text descriptions as needed.
  • Label: Label each of the items on the page to make it easy for anyone to understand what they're looking at. Alternatively, number the items and attach a legend with descriptions to keep the diagram less cluttered.
  • Draw Connecting Lines: Use lines with directional arrows to show how each component is related and connected to another.
