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.

Example of DFD for Online Store (Data Flow Diagram)

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw DIAGRAM enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols.

Building Drawing Software for Design School Layout

Classroom is the place where the pupils spend most of time, so it must to attract, arouse the interest, to be comfortable that the pupils wanted to go here and to stay longer. The psychologists say that the look of a class greatly affects the children. The first important characteristic is a color, the correct choice of color palette for the training premise helps adjust pupils and students on the right mood, promotes a thinking, activity, creativity and concentration. The most favorable colors are yellow, peach, beige, they attract attention and stimulate mental activity. As for the desks and other furniture, they should to be safe, quality, and to be arranged taking in account the room's size, lighting and age of pupils. For the primary classes are perfectly suited various illustrations on the walls. Use ConceptDraw DIAGRAM building drawing software tools and vector design elements from School and Training Plans solution for development School layouts and floor plans, furniture and equipment plans for School or Training offices, Design plans for classrooms, auditoriums and cabinets.

Communication Network Topology

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park. A communication network topology is defined by the evaluating costs of the states. Each state represents the possible distribution of the hubs and remote nodes to nodes of the communication network.
