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.

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.

Every engineering project starts from a terms of reference document. The next stage of developing is a technical drawing, which requires using appropriate software. However, revisions and discussions about requirements are possible at any stage of development.
This technical drawing demonstrates a schematic flow diagram of pulp reclaiming. This diagram of magnetite pulp reclaiming is created using ConceptDraw Chemical and Process engineering solution, The solution delivers more than 460 vector graphic icons and connectors. Generally, it is intended for designing process and instrumentation diagrams (P&ID) for chemical and process engineering. block flow diagrams (BFD), process flow diagrams (PFD) for chemical industry.

All computer networks differ by various params, and their size is one of them. As global area networks are the biggest, personal area (PAN) networks are the smallest. Personal computers, smartphones and other devices that have possibility to connect to Internet form a personal network.
This diagram was created using ConceptDraw Computer Network Diagrams to represent a typical components of Personal area network. A personal area network (PAN) is the connection of IT devices around an individual person. This sample of personal area network involves a notebook, a personal digital assistant (PDA), and a portable printer. Commonly a PAN contains such wireless devices as mouse, keyboard, smartphone and tablet. A wireless connection is typical for a PAN.

A network diagram is used to depict the topology of a computer network or, talking more broadly, any telecommunications network in general. In order for a computer network diagram to be understandable, clearly identifiable icons must be used for each network appliance. Cisco network templates, also called Network Topology Icons, is a brand of symbols developed and used by Cisco. Since Cisco Systems is the largest networking company in the world, it's list of networking symbols is widely recognized and exhaustive.
The diagram of the ISG network topology diagram illustrates the Cisco Intelligent Services Gateway. Since Cicso company offers service providers a possibility to provide control of state and resources in a broadband network, network architects and engineers need some facilities to create ISG topology diagrams.This Cisco ISG network diagram was created in ConceptDraw DIAGRAM using its solution for Cisco network diagrams. The vector library of this solution comprises over 500 icons of Cisco hardware and accessories. They can be used to design LAN, WAN, ISG and other Cisco equipped network diagrams.
