Tree Network Topology Diagram

A Tree network topology (Hierarchical topology) is a hybrid network topology that contains the combination of two or more star networks connected via bus networks. Each star network is a LAN (local area network) with central computer or server and workstation nodes connected to it. The central computers of star networks are connected to a main cable that is called a bus. Each node of the Tree network can have an arbitrary number of child nodes, you can easy add/remove the separate workstations and even the whole star networks, the failure of one workstation will not affect the work of others. This topology is ideal solution when workstations are located in groups within a small physical region, rarely is used in WAN configurations. Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park contains templates, samples and numerous libraries of predesigned vector stencils of computer network devices and equipment, which can be effectively used for designing various network topologies diagrams, including Tree Network Topology.

Network Layout

The Network Layout Diagram visually illustrates the arrangement of computers, nodes and other network appliances, such as servers, printers, routers, switches, hubs, and their relationships between each other. The network layout and placement of servers greatly influence on the network security and network performance. Elaboration of robust Network Layout Diagram is especially important when visualizing already existing network in order to understand its complexity; when troubleshooting the network issues; designing, documenting and implementing new network configurations; extending, modifying, or moving an existing network to other location. Through the careful thinking the network plan and designing the clear Network Layout Diagram, you can be confident in result on the stage of network implementation and to solve faster the problems appearing in network infrastructure. ConceptDraw PRO enhanced with Computer Network Diagrams solution from Computer and Networks area perfectly suits for drawing Network Layout Diagrams for different network topologies.

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 PRO with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

Network wiring cable. Computer and Network Examples

To connect two or more network devices are used the network cables. There are more different types of the network cables: Coaxial cable, Optical fiber cable, Twisted Pair, Ethernet crossover cable, Power lines and others. They are used depending of the network topology, size, protocol. This example was created in ConceptDraw PRO using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

How To use Switches in Network Diagram

Special libraries of highly detailed, accurate shapes and computer graphics, servers, hubs, switches, printers, mainframes, face plates, routers etc.

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 PRO 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.

Cisco Routers. Cisco icons, shapes, stencils and symbols

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

Bus Network Topology

Bus Network Topology is a network topology that represents one shared cable (called a bus or backbone) to which are directly connected all workstations or computers of the network. At the ends of the cable are situated the terminators for prevention the signal reflection. All workstations at Bus Network Topology have equal rights and transfer the information sequentially, one after another. The message sent by one of workstations is extended on all computers of the network and each computer checks to whom it is addressed, if for him, then processes it. Addition of new subscribers to the "bus" is quite simple, the failures of individual computers are not dangerous, and the lack of a central subscriber even more increases its reliability. Computer and Networks solution included to Computer and Networks area of ConceptDraw Solution Park offers templates, samples and numerous vector stencils libraries that can be used to effectively design different physical and logical network topologies diagrams for wireless and wired computer networks, including Bus Network Topology.
