Telecommunication networks.
Computer and Network Examples
A Telecommunications network is a network of nodes, links, trunks and telephone switches that are connected, operated by telephone companies and realize telephone, audio, visual and data communications among the users. The telecommunications network can also include Internet, microwave, wireless equipment. The nodes are connected by transmission links and use the circuit switching, message switching or packet switching to pass the signal to the terminals that have the unique addresses. The set of network addresses is called the address space.
In modern telecommunications networks each user is connected to one of the nodes and each link is called a communications channel (it can be wire, fiber-optic cable, radio waves).
The examples of the telecommunications networks are: telephone networks, Internet, computer networks, wide area networks (WAN), local area networks (LAN), virtual private networks (VPN), PTSA, aeronautical ACARS network, global Telex network, etc.
Computer and Networks Area for ConceptDraw DIAGRAM provides professional looking examples, the libraries with ready-to-use predesigned vector stencils to help you create the Telecommunications Networks quick, easy and effective.
Example 1. Telecommunication network.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Telecommunications network.
The diagrams designed with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

The reliability is a cornerstone for any corporate computer network. If you want to provide a high fault tolerance, a mesh network topology would be the solution. The main advantage of this network is that every node can work as a commutator, although it’s not easy to set up this kind of network.
A mesh network topology may be full, or partial. Full mesh network means that each node of the network (computer, workstation or other equipment) is connected directly to each of the other nodes. A partial mesh topology means that a part of nodes are connected with a whole network, and the other part of nodes are only connected to those equipment, they exchange the majority of data. This illustration shows schematic diagram of a partial mesh network containing six nodes. Each node is represented as a circles and connections are drawn as straight lines. The connections may be both wired and wireless. This scheme can be used to make the specific logical or physical network diagrams by means the ConceptDraw Computer and Networks solution.

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.

The Internet is a giant computer network which connects computers all over the world. It is integral part of human society and business. But the serious question for network engineers, designers, lawmakers and enforcers is the need for protect the Internet networks from the Internet crimes, hacking and attacks. There are quite a number of hardware, software and physical methods of protection against them.
The samples you see on this page were created in ConceptDraw DIAGRAM using the tools of Network Security Diagrams Solution for ConceptDraw DIAGRAM software. They show protection networks with Firewalls and other network security devices.

It doesn’t matter what kind of business you have, a bar or a gym, there are common concepts for any of them. One of those concepts is accounting, and to facilitate the work with the figures, you can use accounting flowchart symbols and create a clear and representative scheme. You can create flowchart for auditing, tax accounting and even for planning your own budget.
A graphical tool for displaying successive processes is flowchart. This method is mostly suited to represent an accounting process. The sequence of steps in the accounting process usually consists of standard accounting procedures, that can be depicted by using a minimal number of symbols, applied for the basic flowcharting. The advanced opportunity to create professional Accounting Flow charts is provided by ConceptDraw Accounting Flowcharts solution. It includes contains a library of accounting flowchart symbols used when drawing the accounting process flow.

Of course it is possible to keep network records in text documents, but it is very difficult to use them later. A more sound way to keep such documentation is to create a network diagram that might represent either logical network structure or physical. These diagrams are easy to understand and you will thank yourself later.
There is a physical network diagram. It is a tool to represent, maintain and analysis of network equipment and interconnections. Network diagram depicts the actual network information in the attractive clear graphic form. One can learn here the LAN cable length, telecommunication type and carrying capacity. The diagram depicts servers, IP address and domain name as well. Also it shows location of hubs, switches, modems, routers, and other network equipment. The sets of special symbols and images delivered with ConceptDraw Network Diagrams solution are used to show network components. Symbols have a standard view. Therefore, various specialists can read the network diagram without any discrepancies.

Data processing can be very complex sometimes. If you are interested in facilitating your work with data, it’s time to learn how to draw flowcharts with special software or using just a piece of paper. The list of flowchart basic symbols includes rectangles, diamond, ellipses etc. and is used to represent processes, actions, decisions or data processing.
A well-done flowchart bring the clearness of the sequence of a process stages. There are number of symbols that can be used in flow charts to show various sorts of steps. The basic flowchart can be created using a few of them: Process, Decision, Start/Finish. A basic element of a flowchart represents a simple action and looks like a box, that contains a description of the action. The depicting of actions sequence is made with arrows between corresponding action boxes, as you can see on the sample diagram. Also it shows the symbols for flowchart start and finish steps. ConceptDraw Flowcharts solution provides the ability to build basic flow charts as well as the ones of any size and complexity with a minimum of actions.
