Star Network Topology

Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful. The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

"Verification and Validation of Computer Simulation Models is conducted during the development of a simulation model with the ultimate goal of producing an accurate and credible model.
"Simulation models are increasingly being used to solve problems and to aid in decision-making. The developers and users of these models, the decision makers using information obtained from the results of these models, and the individuals affected by decisions based on such models are all rightly concerned with whether a model and its results are “correct”". This concern is addressed through verification and validation of the simulation model.
Simulation models are approximate imitations of real-world systems and they never exactly imitate the real-world system. Due to that, a model should be verified and validated to the degree needed for the models intended purpose or application.
The verification and validation of simulation model starts after functional specifications have been documented and initial model development has been completed. Verification and validation is an iterative process that takes place throughout the development of a model." [Verification and Validation of Computer Simulation Models. Wikipedia]
The IDEF0 diagram example "Model validation" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the IDEF0 Diagrams solution from the Software Development area of ConceptDraw Solution Park.

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Chemistry solution from the Science and Education area is a powerful chemistry drawing software that is ideal for quick and easy designing of various: chemistry drawings, scientific and educational chemistry illustrations, schemes and diagrams of chemical and biological lab set-ups, images with chemical formulas, molecular structures, chemical reaction schemes, schemes of labware, that can be then successfully used in the field of science and education, on various conferences, and so on.

Block Diagram Creator

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Block Diagrams Solution from the "Diagrams" Area is a powerful Block Diagram Creator.

Electrical Drawing Software and Electrical Symbols

Any electrical device could not be created without electrical diagram, wiring also cannot be laid without pre-designed and approved scheme or plan. Electrical drawing is a type of technical drawing that depicts scheme of some electrical device and includes the information about power, lighting, etc. Electrical plan designed for architectural or engineering project visually displays location of electrical devices and connections. ConceptDraw DIAGRAM is ideal electrical software for construction professional-looking Electrical Circuits, Electrical Schematics, Electrical Layouts, Electrical Wiring, Automotive Wiring, Cabling Layout Diagrams, Circuits and Logic Schematics, Logic Gate Diagrams, Digital Circuits, Parallel Circuits, Blue Prints with help of 926 standard electrical symbols offered by 26 libraries of Electrical Engineering solution from the Engineering area for ConceptDraw DIAGRAM. It makes drawing Electrical diagrams very easy even for beginners, and also extends your work with various export methods.

Cisco Switches and Hubs. Cisco icons, shapes, stencils and symbols
Cisco switches and hubs deliver the best performance, and often used as network solutions for small businesses, enterprises, data centers. Cisco switches are the core interconnect devices of each computer network. The numerous Cisco switches specifically designed for various applications. Network switches are separated for two types: fixed configuration and modular switches. The fixed configuration switches deprecate swapping or adding another module, and vice versa for modular switch.

WLAN

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Wireless Networks Solution gives the ability to its users to create professional looking WLAN schemes and diagrams quick and easy.

Virtual networks. Computer and Network Examples

A Virtual network is a computer network that consists of virtual network links, i.e. between the computing devices there isn't a physical connection. Well known forms of network virtualization are virtual networks based on the virtual devices (for example the network based on the virtual devices inside a hypervisor), protocol-based virtual networks (VLAN, VPN, VPLS, Virtual Wireless network, etc.) and their combinations. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual network.
