Electrical Symbols — Switches and Relays

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations. 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.

Cross-functional flowchart - Providing telecom services

This swim lane diagram sample shows the telecom services process flow.
"Telecommunication is communication at a distance by technological means, particularly through electrical signals or electromagnetic waves. ...
Electrical and electromagnetic telecommunication technologies include telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, communications satellites and the Internet." [Telecommunication. Wikipedia]
"A telecommunications service provider or TSP is a type of communications service provider that has traditionally provided telephone and similar services. This category includes incumbent local exchange carriers, competitive local exchange carriers, and mobile wireless communication companies. ...
While some people use the terms "telecom service provider" and "communications service provider" interchangeably, the term TSP generally excludes Internet service providers (ISPs), cable companies, satellite TV, and managed service providers. ...
TSPs provide access to telephone and related communications services." [Telecommunications service provider. Wikipedia]
The cross-functional flowchart example "Providing telecom services" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cross-Functional Flowcharts solution from the Business Processes area of ConceptDraw Solution Park.

Electrical Symbols — VHF UHF SHF

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. 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.

Metropolitan area networks (MAN). Computer and Network Examples

A Metropolitan Area Network (MAN) is a great computer network located on the large geographical area or region. It is a network bigger than Local Area Network (LAN), but territorially smaller than Wide Area Network (WAN), its diameter usually ranges from 5 to 50 kilometers. MAN usually includes several buildings or even the whole city (metropolis). It is based on high data rate compounds using the fiber channels and other digital data transmission channels. MAN includes a lot of communicating devices, for its construction are used multiple routers, switches and hubs. MAN can combine together several Local Area Networks or Campus Area Networks located in different buildings within a city and provides the Internet connectivity for them. Solutions included to Computer and Networks Area for ConceptDraw Solution Park are the real godsend for those who want design Computer Network Diagrams, and among others the Metropolitan Area Network Diagrams.
