A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
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 ...
In general, the more interconnections there are, the more robust the network is; but the more expensive it is to install. Therefore, most network diagrams are arranged by their network topology which is the map of logical interconnections of network hosts. Common topologies are: Bus network: all nodes are connected to a common medium along this ...
A network's physical topology is a particular concern of the physical layer of the OSI model. Examples of network topologies are found in local area networks , a common computer network installation. Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric ...
Graphic representation of a minute fraction of the WWW, demonstrating hyperlinks.. Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics.
The symbols from left to right are: stiffness element (e.g. spring), mass (rigid body), mechanical resistance (e.g. damper), force generator, velocity generator. The symbols for generators depend on which mechanical–electrical analogy is being used. The symbols shown relate to the impedance analogy.
Data flows clockwise between entities (i.e., the symbol F1 → F2, in Figure 4, indicates data flowing from function F1 to function F2; the symbol F2 → F1 indicates the feedback). That which passes across the interface is defined in the appropriate squares. The diagram is complete when the user has compared each entity to all other entities.
In electrical engineering, examples include the symbolic languages developed for network diagrams used in computing. [ 8 ] [ 9 ] Ladder logic was originally a written symbolic language for the design and construction of programmable logic control (PLC) operations in mechanical and control engineering .
