A network diagram is a systematic representation of the arrangement of computer components like nodes, routers, hubs, firewalls, etc. This diagram works in such a way that all the devices could interact with each other hassle-free. All the devices in this diagram have their separate symbols, and links connect them to give meaning to the diagram.
Why do you need it?
The network diagrams show all the links which make the network easy to install as well as redundancy in installation errors. If you need an update in your network, then coordination with these diagrams is very helpful. You can even keep track of all the components using this diagram.
What kind of data you can visualize with it?
If you want to set up a Local Area Network (LAN) in your office or home, then a network diagram is your first priority step. This visualization makes it easy to lay the network effectively. You can even troubleshoot future errors easily in your network using this.
