A network diagram is a visual representation of a computer network’s architecture. It is used to map out the structure of a network with various symbols and line connections . Network diagrams are useful for understanding how a network is set up and how its components are connected. They can be used to identify potential issues, plan upgrades, and troubleshoot problems .
There are different types of network diagrams, such as logical network diagrams and physical network diagrams. Logical network diagrams show how data flows through a network, while physical network diagrams show the physical components of a network, such as routers, switches, and servers .
Creating a network diagram involves identifying the components of the network and their relationships, then mapping them out using symbols and lines . There are many tools available to help create network diagrams, such as SmartDraw, EdrawMax Online, and Microsoft Visio .
