Complete Network Topology
Network Topology refers to layout of a network. How different nodes in a network are connected to each other and how they communicate is determined by the network's topology.
Network Topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Topologies are either physical (the physical layout of devices on a network) or logical (the way that the signals act on the network media, or the way that the data passes through the network from one device to the next).
Network topology recognizes eight basic topologies:
- Point-to-point Topology,
- Bus Topology,
- Star Topology,
- Ring or circular Topology,
- Mesh Topology,
- Tree Topology,
- Hybrid Topology,
- Daisy chain Topology.
Example 1. 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.
This sample shows the complete network topology or fully connected network topology.
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.

This sample shows the Hypercube network topology.
Network topology is the topological structure of the computer network.
Hypercube is a type of the toroidal network. The Torus is a topology with n-dimensional grid network with circularly connection of the nodes. If the number of nodes along each dimension of the toroidal network is 2, it is a Hypercube network topology.

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology.
There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

The digital communication is a physical transfer of the data over a point-to-point or point-to-multipoint communication channel. Channels can be copper wires, optical fibres, wireless communication channels, etc. The data are realized as electromagnetic signals (radiowave, microwave, electrical voltage, etc.).
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Digital Communication Network diagram.

A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks.
Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.

Infrastructure is very important part of any district, and educational buildings presence is one of the factors. Another not less important thing is the school design, because it influences the children's’ sense of aesthetics. To develop a harmonic school layout, use a proper software.
This image represents the School layout library that is supplied with ConceptDraw School and Training Plans solution. The library contains a set of vector graphic objects that will be in help while drawing a layout of classroom. Any lecturer desires to organize the layout of the classroom for the best student advantage. Students must be focused and be engaged in the learning process. The classroom places organization is an important element of a students learning. It is significant for a lecturer to set up a classroom layout and change it time to time to support lectures, to invoke disputes or solve any organizational issues. By using ConceptDraw DIAGRAM you can easily plan how to re-arrange the desks in the class room to maintain visual control of your class and build a friendly environment in the classroom.

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data.
This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.

Voice-over-Internet protocol (VoIP) is a protocol of the voice communications and multimedia sessions through the Internet or other packet-switched networks. VoIP systems use the data compression techniques, encapsulated in a data-packet stream over IP. They allows users to use regular telephone networks through any internet service provider and anywhere. VoIP is also called IP telephony, Internet telephony, Voice over broadband (VoBB).
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the VoIP Network.
