What Is a Wireless Network?

What Is a Wireless Network? Wireless network refers to any type of computer network that uses wireless (usually, but not always radio waves) for network connections. Wireless computer network diagrams help system administrators and network engineers to find out amount and type of equipment needed for each office WLAN.

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.

Electrical Symbols — Analog and Digital Logic

Digital electronics or digital (electronic) circuits are electronics that handle digital signals – discrete bands of analog levels – rather than by continuous ranges (as used in analogue electronics). All levels within a band of values represent the same numeric value. Because of this discretization, relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry. 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.

ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.

Audio - Vector stencils library

The vector stencils library "Audio" contains 91 audio, sound and music icons. Use it to design your audio, video and multimedia illustrations, presentations, web pages and infographics with ConceptDraw PRO diagramming and vector drawing software.
"Digital audio refers to technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form. Following significant advances in digital audio technology during the 1970s, it rapidly replaced analog audio technology in most areas of sound production, sound engineering and telecommunications. Sound is converted to an analog electrical signal by a microphone, then an analog-to-digital converter (ADC), typically using pulse-code modulation, is used to convert it to a digital signal. A digital-to-analog converter performs the reverse process, converting a digital signal back into an analog signal, which can be converted to an audible sound by a loudspeaker. Digital audio systems may include compression, storage, processing and transmission components. Conversion to a digital format allows convenient manipulation, storage, transmission and retrieval of an audio signal." [Digital audio. Wikipedia]
The vector stencils library "Audio" is included in the Audio, Video, Media solution from the Illustration area of ConceptDraw Solution Park.

Electrical Symbols — Stations

A power station is an industrial facility for the generation of electric power. Most power stations contain one or more generators, a rotating machine that converts mechanical power into electrical power. The relative motion between a magnetic field and a conductor creates an electrical current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Others use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, wave and hydroelectric. 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.

Computer Network Diagrams

Electrical Symbols, Electrical Diagram Symbols

When drawing Electrical Schematics, Electrical Circuit Diagrams, Power Systems Diagrams, Circuit and Wiring Diagrams, Digital and Analog Logic Schemes, you will obligatory need the electrical symbols and pictograms to represent various electrical and electronic devices, such as resistors, wires, transistors, inductors, batteries, switches, lamps, readouts, amplifiers, repeaters, relays, transmission paths, semiconductors, generators, and many more. Today these symbols are internationally standardized, so the diagrams designed using them are recognizable and comprehensible by specialists from different countries. Electrical Engineering Solution included to ConceptDraw Solution Park provides 26 libraries with 926 commonly used electrical schematic and electrical engineering symbols making the reality the easy drawing of Electrical diagrams, schematics and blueprints. Now you need only a few minutes to create great-looking Electrical diagram, simply choose required electrical design elements from the libraries, drag them on the needed places at the document and connect in a suitable way.

Electrical Symbols — Power Sources

A voltage source is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source. Real-world sources of electrical energy, such as batteries, generators, and power systems, can be modeled for analysis purposes as a combination of an ideal voltage source and additional combinations of impedance elements. 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.

Telecommunication networks - Vector stencils library

The vector stencils library "Telecommunication networks" contains 32 clipart images of telecommunication network devices and equipment for drawing telecom network diagrams.
"A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals.
The transmission links connect the nodes together. The nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal.
Each terminal in the network usually has a unique address so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space." [Telecommunications network. Wikipedia]
