For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
A network's logical topology is not necessarily the same as its physical topology. For example, the original twisted pair Ethernet using repeater hubs was a logical bus topology carried on a physical star topology. Token Ring is a logical ring topology, but is wired as a physical star from the media access unit.
Broadly, there are four types of tools that help create network maps and diagrams: Hybrid tools; Network Mapping tools; Network Monitoring tools; Drawing tools; Network mapping and drawing software support IT systems managers to understand the hardware and software services on a network and how they are interconnected. Network maps and diagrams ...
The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.
(For example, all of the devices that together form and use a Wi‑Fi network called "Foo" are a service set.) A service set forms a logical network of nodes operating with shared link-layer networking parameters; they form one logical network segment. A service set is either a basic service set (BSS) or an extended service set (ESS).

Though network documentation can be done by hand, large organizations must use network documentation software, including diagramming tools, inventory management, and circuit and cable traces. Examples include draw.io, Graphical Networks' netTerrain, [4] Microsoft Visio, [5] Docusnap, Gliffy, [6] Opnet's Netmapper, and XIA Configuration. [7]
A Bachman diagram is a certain type of data structure diagram, [2] and is used to design the data with a network or relational "logical" model, separating the data model from the way the data is stored in the system. The model is named after database pioneer Charles Bachman, and mostly used in computer software design.
