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 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.

A computer network diagram for a large network can be complicated and difficult both to understand and to draw. To learn how to deal with complex network diagrams, start with a basic network diagram, showing only the primary network devices and the connections between them. There are software tools to help you with that, such as ConceptDraw DIAGRAM , that include templates and examples for simple and common network diagrams.
The ConceptDraw solution for making computer network diagrams delivers over a thousand of vector objects, composed into the forty vector libraries that were developed to support drawing of professional-looking computer network diagrams. This diagram of computer network can be used by system administrator as a basic template for making the custom network diagram. Since the responsibilities of network or system administrator include documenting of computer network, drawing network diagrams is an important part of their work.

If we divide computer networks by scale, we get several main categories. The smallest network is PAN, as it connects personal devices themselves, and as the number of users grows, a local area network can be recognized, and campus area networks (CAN) connects several local networks located within some area like a university or a corporation. Computers connected to CAN share public educational materials and list of CAN network examples includes such prestigious universities like Stanford and Carnegie Mellon.
This is an example of a computer network diagram created for a campus area network. It was created using using ConceptDraw solution for the Computer and Network diagramming. The specific of this sample campus network is its distribution. It is rather broad to embrace a big campus territory. This diagram can be applied as a template for designing custom area network topology diagram for a particular educational institution.

When talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems.
The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical.
This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.
