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).

Drawing the diagrams we try to find in help the powerful software and now we have the ConceptDraw DIAGRAM. The ability easily create the SDL diagrams is made possible thanks to unique Specification and Description Language (SDL) Solution from the Industrial Engineering Area of ConceptDraw Solution Park. This solution extends ConceptDraw DIAGRAM 2 libraries - SDL Connectors and SDL Diagrams that contain 70 predesigned SDL flowchart symbols.

Every corporate network is unique, though there are guidelines and best practices in developing networks. As it is quite difficult to implement a pure topology within a company, using a hybrid network topology is considered a better solution. As a rule, such network assembles advantages and features of source topologies.
This diagram is an example of the Hybrid network. This type of network topology means a conjunction of other network topologies. Such as star-bus, ring-mesh topologies, etc. It should be obviously diverse networks. The final computer network inherits both advantages and disadvantages of its ingredients. Using the ConceptDraw Computer and Networks solution including vector graphic libraries and templates one can develop professional custom network diagrams of any topology and complexity.

There are many ways to describe a database structure. One of the most usual is to draw an entity relationship diagram (ERD) using a Crow’s Foot notation to represent database elements. If you don’t want to draw it on paper, you should use an appropriate software.
An entity-relationship (ER) diagram is used to show the structure of a business database. ERD represents data as objects (entities) that are connected with standard relationships symbols which Illustrate an association between entities. ERD, there is a wide range of ERD notations used by data bases architects for reflecting the relationships between the data entities. According to the crow’s foot notation relationships are drawn as single labeled lines designating a certain kinds of relationship. Crow foot notation is a most frequently used ERD standard, because of improved readability of diagrams, with a more accurate use of space on the page.
