Network Diagram Symbols and Icons

Visual representation is always better and easy to understand compared to plain text. Using graphics to explain something makes it clear and creative. A network diagram uses Network Symbols to showcase various network components and make it interactive for the reader. Learn more about network diagrams and how it helps with project management in this article.

1. What Are Network Diagram Symbols and Icons

The network diagram represents devices, components of a network and their interrelation. It uses network diagram symbols to make everything easy to understand. As you know, depicting computer connection gets more complex as it moves on, and it becomes nearly impossible to represent telecommunication networks.

With the help of network diagram symbols, you can easily show local granular networks limited to a small area to high-coverage networks spread across cities. Icons work in the same way as symbols and make visual presentations simple. Learning network symbols makes documentation efficient, and with network diagram symbols, you get a firm footing for future network connections.

2. Basic Network Diagram Symbols

A network diagram illustrates all components of a network. It showcases the flow of information in the network. It uses network symbols to represent communication between various devices and ongoing processes. It also includes many other elements like network segments, traffic flow and routing protocols to make things clear.

Please take a look below to learn and understand the basic network diagram symbols and their uses.
