Hybrid Network Topology

A network topology is the topological structure or the arrangement of different elements of computer network. There are several basic types of network topologies, such as star, ring, bus, mesh. But the most popular is a combination of two or more diverse basic network topologies, which is known as hybrid network topology. The examples of hybrid topology are: star-bus, star-ring topologies, etc. Each resulting hybrid topology has its own features, advantages and limitations of its components. Hybrid network topologies are more flexible, reliable, and have increased fault tolerance, the faults in them can be easily diagnosed and corrected, new nodes can be easily added. But at the same time hybrid topologies often are sufficiently expensive and difficult for managing. ConceptDraw DIAGRAM diagramming and vector drawing software supplied with the tools of Computer Network Diagrams solution from Computer and Networks area is perfect for schematic description various types of computer network topologies and easy designing Hybrid network topology diagrams.

Wireless 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. This sample shows the Wireless network topology. Wireless network topology is a logical topology. It shows how the computers connect and interact each other when there is no physical connection, no cables connecting the computers. The computers communicate each other directly, using the wireless devices. Wireless networks can have infrastructure or ad hoc topology.

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

Cisco Network Topology represents the arrangement of worldwide recognized and standardized Cisco network symbols, icons, shapes, and stencils which help visualize the schemes of computer networks. Any equipment used in Cisco networks is also named a node and network topology diagram represents the scheme of connection the used nodes. Cisco Network Diagram illustrates how the signals enter on the networked devices and how the data spread within a network from one device to another. These diagrams are useful for engineers while constructing computer networks and working with them. Cisco Network Diagrams solution included to Computer and Networks area of ConceptDraw Solution Park contains quick-start templates, professionally designed samples and examples, and numerous libraries with a lot of predesigned vector design elements, icons, and shapes of Cisco equipment, components, devices, links which provide for ConceptDraw DIAGRAM users a perfect possibility of simple and quick drawing Cisco Network Diagrams and Schematics, Network Designs and Maps of any complexity.

Network Topology

Network topology describes a way of organizing the physical connectivity of computers and other network components. All networks are built based on basic topologies: bus, star, ring, mesh. The basic topologies themselves are not complicated, but in practice we often face with their complex combinations. A particular choice of one or another topology affects the composition of necessary network equipment, opportunity of network expansion and method of network management. Bus topology is widespread and the most simple, it uses a single cable along which are connected all computers. In Star topology each computer is connected by a separate cable to common hub device located in a center of network. In networks with Ring topology, the data are transmitted around the ring from one computer to another, usually in one direction. In Mesh networks, only the computers with intensive data exchange are connected. ConceptDraw DIAGRAM software extended with powerful tools of solutions included to Computer and Networks area, contributes to high-quality design Network Topology Diagrams of different types.

Wiring Diagrams with ConceptDraw DIAGRAM

A Wiring Diagram is a comprehensive schematic that depicts the electrical circuit system, shows all the connectors, wiring, signal connections (buses), terminal boards between electrical or electronic components and devices of the circuit. Wiring Diagram illustrates how the components are connected electrically and identifies the wires by colour coding or wire numbers. These diagrams are necessary and obligatory for identifying and fixing faults of electrical or electronic circuits, and their elimination. For designing Wiring Diagrams are used the standardized symbols representing electrical components and devices. ConceptDraw Solution Park offers the Electrical Engineering solution from the Engineering area with 26 libraries of graphics design elements and electrical schematic symbols for easy drawing various Wiring Diagrams, Electrical Circuit and Wiring Blueprints, Electrical and Telecom schematics of any complexity, Electrical Engineering Diagrams, Power Systems Diagrams, Repair Diagrams, Maintenance Schemes, etc. in ConceptDraw DIAGRAM software.

OSPF Network. Computer and Network Examples

OSPF is an interior gateway protocol (IGP), it is widely used in large enterprise networks. OSPF routes the IP packets within a single routing domain. It gathers the information about the link state from the routers and makes the network topology map. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the OSPF diagram.

Network Diagramming with ConceptDraw DIAGRAM

At the moment computer networks are widespread, various types of computer networks are constructed around the world, operate and interact with each other. There are many kinds of computer networks that differ in the transmission medium, in communications protocols, in size, topology, organizational intent, and also in territorial basis. There are popular such types of computer networks as Global Area Network (GAN), Wide Area Network (WAN), Metropolitan Area Network (MAN), Local Area Network (LAN). ConceptDraw DIAGRAM is a powerful network diagramming software, perfect for software engineers, software designers and software developers who need to draw Computer Network diagrams, designs, schematics, and network maps in no time. The pre-drawn shapes representing computers, network devices and smart connectors offered by ConceptDraw solutions help to create the accurate diagrams and documentation, represent computer network topologies and designs, depict Computer network architectures, logical, physical, cable networks, and vehicular networks.

Complete 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 complete (fully connected) topology is a network topology in which there is a direct link between all pairs of nodes. In a fully connected network with n nodes, there are n(n-1)/2 direct links. Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the multiple paths for data that are provided by the large number of redundant links between nodes.

ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.
