"Fault-tolerant computer systems are systems designed around the concepts of fault tolerance. In essence, they have to be able to keep working to a level of satisfaction in the presence of faults. ...
Most fault-tolerant computer systems are designed to be able to handle several possible failures, including hardware-related faults such as hard disk failures, input or output device failures, or other temporary or permanent failures; software bugs and errors; interface errors between the hardware and software, including driver failures; operator errors, such as erroneous keystrokes, bad command sequences, or installing unexpected software; and physical damage or other flaws introduced to the system from an outside source." [Fault-tolerant computer system. Wikipedia]
The computer network diagram example "Cisco LAN fault-tolerance system" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

Graphic Technologies

Graphics Technology looks at how to communicate graphically, develop ability to create graphical presentations for varied needs, understand standards and special conventions, develop specific techniques and build an understanding of the impact of graphical presentation on society.

If you want to use effective methods for your work, you may need a tool which may let you represent your ideas and goals in graphic way.

Cisco Network Diagrams solution extends ConceptDraw DIAGRAM with the best characteristics of network diagramming software. Included samples, templates and libraries of built-in standardized vector Cisco network icons and Cisco symbols of computers, network devices, network appliances and other Cisco network equipment will help network engineers, network designers, network and system administrators, as well as other IT professionals and corporate IT departments to diagram efficiently the network infrastructure, to visualize computer networks topologies, to design Cisco computer networks, and to create professional-looking Cisco Computer network diagrams, Cisco network designs and schematics, Network maps, and Network topology diagrams in minutes.
"Physical topology refers to the placement of the network's various components, including device location and cable installation...
The shape of the cabling layout used to link devices is called the physical topology of the network. This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling. The physical topology of a network is determined by the capabilities of the network access devices and media, the level of control or fault tolerance desired, and the cost associated with cabling or telecommunications circuits." [Network topology. Wikipedia]
This physical LAN diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

The vector stencils library "Cisco network topology" contains 89 symbols of Cisco network devices and design elements for drawing computer network topology diagrams.
"There are two basic categories of network topologies:
(1) Physical topologies,
(2) Logical topologies.
The shape of the cabling layout used to link devices is called the physical topology of the network. This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling. The physical topology of a network is determined by the capabilities of the network access devices and media, the level of control or fault tolerance desired, and the cost associated with cabling or telecommunications circuits.
The logical topology in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices." [Network topology. Wikipedia]
The symbols example "Cisco network topology - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
