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.

How To use House Electrical Plan Software →

Electrical plan is a document that is developed during the first stage of the building design. This scheme is composed of conventional images or symbols of components that operate by means of electric energy. To simplify the creation of these schemes you can use house electrical plan software, which will not require a long additional training to understand how to use it. You only need to install the necessary software ant it’s libraries and you’ll have one less problem during the building projection. Any building contains a number of electrical systems, including switches, fixtures, outlets and other lightening equipment. All these should be depicted in a building electrical plans and included to general building documentation. This home electrical plan displays electrical and telecommunication devices placed to a home floor plan. On the plan, each electrical device is referenced with the proper symbol. Electrical symbols are used for universal recognition of the building plan by different persons who will be working on the construction. Not all possible electric symbols used on a certain plan, so the symbols used in the current home plan are included to a legend. The electrical home plan may be added as a separate document to a complete set of building plans.House Electrical Plan Software

Local area network (LAN). Computer and Network Examples →

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.Local area network (LAN) diagram

Electrical Symbols — Transmission Paths →

Variable delay elements are often used to manipulate the rising or falling edges of the clock or any other signal in integrated circuits. Delay elements are also used in delay locked loops and in defining a time reference for the movement of data within those systems. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.Electrical Symbols — Transmission Paths *
