Cisco Network Topology. Cisco icons, shapes, stencils and symbols

The Cisco Network Diagrams solution uses Cisco network symbols and Cisco icons to visualize computer networks. Cisco Network Topology is the arrangement of the Cisco symbols that display scheme of computer network.
Any Cisco equipment on the network are named like node. Network diagram topology commonly designed within connected nodes. Cisco icons are worldwide acknowledged and mainly established as standard icons for network diagrams. You may use them loosely, but you may not rework them.
The Cisco Network Diagram shows how signals act on the networked devices, or how data routes on the network from one device to the other. There are number of physical network typologies that engineers use while constructing computer networks.

Cisco Telepresence. Cisco icons, shapes, stencils and symbols

The ConceptDraw vector stencils library Cisco Telepresence contains videoconference equipment symbols for drawing the computer network diagrams.

Cisco Optical. Cisco icons, shapes, stencils and symbols

The ConceptDraw vector stencils library Cisco Optical contains symbols for drawing the computer network diagrams.

Cisco Network Objects in ConceptDraw DIAGRAM

ConceptDraw DIAGRAM is the only application on the Macintosh platform, supplied with a comprehensive Cisco icon set. For graphic solutions that support Windows, only Microsoft Visio has a library of Cisco shapes. ConceptDraw DIAGRAM is a valuable option to many network professionals that use Macintosh computers or work in a combined Mac and PC environment.

Network infrastructure planning is a very important process in the network construction, and the share of time allocated to this within the scope of the entire project may reach 60-80%. A competent and thorough approach to planning contributes to the quick investment return, and also increases the reliability and flexibility of the final system, reducing the probability of additional costs related to the incorrect implementation.
Any planning begins with an analysis of the business requirements to the final system. Basic network parameters, which should be assessed are the scalability, accessibility, cost, speed and safety.
Speed and cost are often mistaken for the most important parameters, and the rest of the parameters aren't even remembered. This is not entirely correct. Initially, it is necessary to assess the business plans for the future, because sometimes it is more profitable to invest more money in the beginning. If the business is to develop, then, consequently, demands on

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

Cisco Network Icons

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Cisco Network Diagrams Solution from the Computer and Networks Area is the best for creating Cisco Network Diagrams thanks to numerous predesigned Cisco network icons.

Cisco Products Additional. Cisco icons, shapes, stencils and symbols

The ConceptDraw vector stencils library Cisco Products Additional contains equipment symbols for drawing the computer network diagrams.

Electrical Symbols — Switches and Relays

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.

26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
