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.

Geo Map - Canada - Nova Scotia

Nova Scotia is one of Canada's three Maritime provinces and constitutes one of the four Atlantic Canada provinces. The vector stencils library Nova Scotia contains contours for ConceptDraw DIAGRAM diagramming and vector drawing software. This library is contained in the Continent Maps solution from Maps area of ConceptDraw Solution Park.

Network diagrams with ConceptDraw DIAGRAM

Network diagram is effective tool for representing and description the network knots and connections between them in comprehensible graphic view, for studying and analysis them. The network administrators and engineers actively use Physical Network Diagrams and Logical Network Diagrams, which are both indispensable when developing and documenting new networks, and managing existing ones. Network diagrams let clearly represent the network configuration and structure, used protocols, addresses, and also names of network objects. Physical Network Diagrams depict the information about telecommunications data, servers, location of network equipment and number of network users. Logical Network Diagrams describe about logical network structure. It is useful to use the ready sets of network clipart, pictures and symbols for indication the network knots on a diagram, such as developed by professionals and offered in large quantity by Computer Network Diagrams solution from ConceptDraw Solution Park.

ER diagram tool for OS X

ER diagram is the most popular database design tool which lets create graphical representations of database tables, their columns and also relationships. As for the Mac users, they are very interested in powerful database diagramming tools and ER diagram tool for OS X to design professional looking E-R Diagrams and ERD drawings. ConceptDraw DIAGRAM software on Mac OS X gives the ability to easy draw ERDs.

Planning a Trip with ConceptDraw PROJECT

Planning a trip is real work; and the better this work is done, the more chances you have to enjoy an interesting itinerary and the trip in general. A good plan is never overloaded. It is always good to stick to the golden mean. Surely, you can create a perfectly accurate and detailed route. However, following it may become a hard task, which will turn your trip from a pleasure into a race to fulfil your own plan.

UML Class Diagram. Design Elements

UML Class Diagrams describes the structure of a system by showing the system's classes, their attributes, and the relationships among the classes.

Network Topologies

Network topology is a topological structure of computer network, which can be physical or logical. The physical topology depicts location of different computer network elements such as computers, cables and other devices. The logical topology visually displays network dataflows from one device to another. Sometimes network logical and physical topologies can be the same. ConceptDraw DIAGRAM diagramming and vector drawing software is powerful for drawing network maps and network topologies diagrams of any kinds and complexity thanks to the Computer Network Diagrams solution from the Computer and Networks area. ConceptDraw STORE proposes collection of network icons libraries and a lot of Network Topology Diagram examples, samples and templates which were created at ConceptDraw DIAGRAM software specially for Computer Network Diagrams solution. There are six basic types of the network topologies: Bus, Star, Ring, Mesh, Tree, Fully Connected. You can fast and easy design professional-looking diagram for each of them using the ConceptDraw DIAGRAM tools. There are plenty of web Visio-like diagramming software available. Web based diagrams software can be powerful, but sometimes it is essential to have desktop software. One of the most advanced diagrams tools like Visio for Mac OS is ConceptDraw DIAGRAM app.

Martin ERD Diagram

The vector stencils library Crow's Foot Notation from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Crow's foot notation such as relationship symbols and entity symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.

DFD Library — Design elements

Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park provides plenty of predesigned templates, samples and DFD vector design elements proposed by three DFD libraries. These DFD library objects are designed to help you effectively model the data flows and functional requirements for the business processes or systems, to design the Process-oriented models or Data-oriented models, Data flowcharts and Data process diagrams, Structured analysis diagrams and Information flow diagrams. There are two different notations used to draw the Data Flow Diagrams (Yourdon & Coad and Gane & Sarson). These notations define the different visual representations for the processes, data stores, data flows, and external entities. ConceptDraw DIAGRAM software provides you with possibility of designing professional-looking Data Flow Diagrams, DFD Models, Data Flow Process Diagrams using any of these notations. Simply drag the predesigned DFD flowchart symbols from the appropriate library and connect by arrows depicting the data flow from one step to another.
