Digital Communications Network.
Computer and Network Examples
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.).
The digital communications are widely used in telecommunication, electrical engineering, computer engineering. In computer engineering the digital communications are used for communication with peripheral devices, in computer networking equipment (such as modems, LAN adapters, hubs, repeaters, etc.).
The digital network interconnects devices and includes a digital network server that communicates with the client workstations. There are used the HTTP, TCP/IP, ATM protocols, the OSI model.
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 Digital Communication Networks quick, easy and effective.

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.

Talking about companies, that have influenced the entire industry, we should mention Cisco and it’s influence on network design. Nowadays, this equipment has became a kind of standard, and Cisco icons, shapes, stencils, symbols and design elements are easily recognized among others. You can use these icons to develop a network diagram of any complexity.
When dealing with creating a pack of network documentation, system administrator often have to depict a network containing a network equipment of such a well-known manufacturer as Cisco. As Cisco has developed its own production standard icons that are strongly recommended to use in Cisco network diagrams. The best way to draw Cisco Network diagram Cisco certified icons is using ConceptDraw solution for Cisco Network Diagrams. Using Cisco symbols library provided by this solution allows system administrator, or network architect to design a prototype of a new network or document an existing one.

The efficiency of any corporate network depends on many factors such as equipment, architecture etc. Moreover, every administer knows that network architecture is a cornerstone for any system. Also, it's easy to make a draft of a network structure using an appropriate diagramming tool.
Designing network architecture diagrams refers to the network structure, including hardware, software, connectivity, protocols of communication and type of transmission: wired or wireless. A high performance, highly reliable, and secure network architecture is critical for the successful deployment and operation of modern communication network. This diagram represents in detail the sample of the network architecture of the three-divisional office. It is designed using vector libraries supplied with ConceptDraw Computer and Networks solution.
