Network Diagram

Network diagrams visually represent the flow of data through a network. Network diagrams are typically used for problem-solving, troubleshooting, and planning. A network diagram may show the physical layout of the network or the logical flow of data through the network. Understanding the different types of network diagrams and the symbols used to create them is important for anyone who wants to work with networks. Network diagrams are usually presented as flowcharts, with symbols representing different devices and connections. Network diagrams are used to visualize and analyze the network's topology, which is the arrangement of devices and links in a network. Network diagrams can also be used to troubleshoot network problems and to plan network upgrades.

Diagram types

There are two main types of network diagrams: physical and logical. Physical network diagrams show the physical layout of the network, including the location of devices and the cables that connect them. Logical network diagrams show the logical flow of data through the network, regardless of the physical layout.

Physical network diagrams

Physical network diagrams are used to show the physical layout of a network, including the location of devices and the cables that connect them. Physical network diagrams can be used to troubleshoot network problems and to plan network upgrades.

Logical network diagrams

Logical network diagrams show the logical flow of data through a network, regardless of the physical layout. Logical network diagrams are used to design and troubleshoot networks.

Symbols

Network diagrams use a variety of symbols to represent different devices and connections. The most common symbols include:
