Personal area (PAN) networks. Computer and Network Examples
A personal area network — PAN is a personal devices network equipped at a limited area. PAN ordinary has such mobile devices: cell phone, tablet, laptop. That type of network could also be wirelessly connected to Internet.
The personal area network concept originates at M.I.T.'s Media Lab thanks to Thomas Zimmerman research. Zimmerman's article the advantage of this technology explains.
A personal area network handles the interconnection of IT devices at the surrounding of a single user. Generally, PAN contains from following such appliances: cordless mice and keyboards, cordless phone, Bluetooth.
A personal area network pros and cons:
- PAN is expedient, lucrative and handy.
- Sometimes has a bad connection to other networks at the same radio bands.
- Bluetooth networks have slow data transfer speed, but comparatively safe.
- Bluetooth has distance limits.
ConceptDraw DIAGRAM is a powerful network diagramming and vector drawing software. It provides the Computer and Networks Area with many Solutions that contain the wide set of ready-to-use predesigned vector stencils and examples to help you design the professional looking Personal area networks (PANs) of any complexity quick and easy.
Example 1. Personal area (PAN) network.
Once you go to the Solutions section on this site, you will see our examples and templates of personal area network which can be very useful in terms of making your own diagram and to have the final version of it looking professional.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Personal area network.
Example 2. Computer and Network Diagrams Solution
The network diagrams designed with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

Functional modeling allows to make complex business processes simple. One of the basic methods is IDEF0 and one of the most effective also. To create a business model, use flowchart symbols.
The IDEF0 library, supplied with ConceptDraw IDEF0 Diagrams solution contains 18 IDEF0 basic notation symbols. All symbols are the vector graphic images what means, that one can customize their size preserving the stable quality. Another library of IDEF0 symbols can be find out in the the Business Process Diagrams solution, included to the Business Processes section of ConceptDraw Solution Park. These libraries composed from just vector objects and are totally compatible. You can apply the IDEF0 symbols from both libraries at your flowcharts, if needed.

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.

Unfortunately, a man can’t predict the future and no one is safe from natural disasters, such as floods, earthquakes, hurricanes or fires. Nonetheless, what you can do to ensure safety for you and your relatives is to create an emergency plan, so everyone will know what to do if emergency happens. Keep that plan simple and train it several times a year so that no one could forget any details of it.
Fire and emergency plans are important to supply people with a visual safety solution. This diagram presents a set of standard symbols used to depict fire safety, emergency, and associated information. Using clear and standard symbols on fire emergency plans provides the coherence of collective actions , helps to avoid embarrassment, and improves communications in an emergent situation. The fire emergency symbols are intended for the general emergency and fire service, as well as for building plans ,engineering drawings and insurance diagrams. They can be used during fire extinguishing and evacuation operations, as well as trainings. It includes vector symbols for emergency management mapping, emergency evacuation diagrams and plans.

Data Flow Diagram is used to depict the flow of data through the system, where it enters and exits the system, as well as where it is stored. To simplify the process of drawing a data flow diagram (DFD), ConceptDraw DIAGRAM provides a DFD Library - design elements that will help you make your diagram as informative, streamlined and understandable as possible. Data flow diagrams are useful to create a general overview of the system or to document major data flows.
Here are the library of symbols used in data flow diagrams (DFD). Data Flow diagrams are graphic means of business process visualization. Any business process may involve the data transfer. It can be easily shown using data flow diagrams. DFDs are used to represent the processing and transformation of data within a business process. One can find out the Vector library of DFD symbols, that is a component of ConceptDraw solution for Data Flow Diagramming and is welcome to use in as addition to the common Conceptdraw DIAGRAM diagramming facilities.
