Local area network (LAN). Computer and Network Examples

Local Area Network (LAN) is a network which consists of computers and peripheral devices connected each other and to the local domain server, and covers a little territory or small number of buildings, such as home, school, laboratory, office, etc. LAN serves for few hundreds of users. It includes many cables and wires, and demands to design previously a Network diagram. All local area network devices can use the shared printers and disk storage. ConceptDraw DIAGRAM is a perfect network diagramming software with examples of LAN Diagrams, templates and predesigned vector objects. ConceptDraw DIAGRAM is the ideal choice for network engineers and network designers who need to draw fast and easy Local Area Network Diagrams, for IT specialists, developers and other IT professionals which need to visualize the communication schemes of LAN and visually document the LAN's physical structure and arrangement in houses, offices and other buildings. Ready-to-use vector objects from Computer Network Diagrams solution will help you design LAN diagrams in minutes.

Personal area (PAN) networks. Computer and Network Examples

Personal area network (PAN) is a network organized on a limited area and used for data transmission between various personal devices, such as computers, tablets, laptops, telephones, different digital and mobile devices, etc. and also for connecting to higher level network and Internet. PAN is used to manage the interconnections of IT devices which surround a single user and generally contains such appliances, as cordless mice, keyboard, phone, and Bluetooth handsets. PANs can be wired with computer buses, or wirelessly connected to the Internet using such network technologies as Bluetooth, Z-Wave, ZigBee, IrDa, UWB, Body Area Network. PANs have a lot of pros and cons, they are expedient, lucrative and handy, but sometimes have bad connection with other networks on the same radio bands, Bluetooth has distance limits and slow data transfer speed, but is comparatively safe. ConceptDraw DIAGRAM diagramming software supplied with numerous solutions of Computer and Networks Area included to ConceptDraw Solution Park perfectly suits for designing the Personal Area Networks.

Cloud Computing Architecture Diagrams

For documenting the Cloud Computing Architecture with a goal to facilitate the communication between stakeholders are successfully used the Cloud Computing Architecture diagrams. It is convenient and easy to draw various Cloud Computing Architecture diagrams in ConceptDraw DIAGRAM software with help of tools of the Cloud Computing Diagrams Solution from the Computer and Networks Area of ConceptDraw Solution Park.

Diagram of a Basic Computer Network. Computer Network Diagram Example

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park. This sample shows the connection scheme of the home WLAN equipment to the Internet.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.

Program Evaluation and Review Technique (PERT) with ConceptDraw DIAGRAM

Program Evaluation and Review Technique (abbr. PERT) is a method developed by Ministry of Defense of the USA in 1958 for the project of creation the missile system Polaris. PERT diagram is one of the tools for project management that lets greatly simplify the planning and scheduling of large and complex projects. PERT diagram provides evaluation of project run-time and labor forces, it helps to analyze the time necessary for execution each of project tasks and the whole project, and to calculate the project critical path. PERT chart depicts the set of tasks connected each other in order of their execution and is constructed according to one of definite rules - AOA (activity on arrow) or AON (activity on node). It doesn't give you ready concrete decisions, but helps to find them. Design easy the PERT diagrams in ConceptDraw DIAGRAM software enhanced with Seven Management and Planning Tools solution from Management area of ConceptDraw Solution Park. You have a possibility to build the PERT chart of any type, but AON variant is easier for building and perception.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior. Applying of SSADM is easy with ConceptDraw DIAGRAM diagramming and vector drawing software and Data Flow Diagram solution.

Network Topologies

Network topology is a topological structure of computer network, which can be physical or logical. The physical topology depicts location of different computer network elements such as computers, cables and other devices. The logical topology visually displays network dataflows from one device to another. Sometimes network logical and physical topologies can be the same. ConceptDraw DIAGRAM diagramming and vector drawing software is powerful for drawing network maps and network topologies diagrams of any kinds and complexity thanks to the Computer Network Diagrams solution from the Computer and Networks area. ConceptDraw STORE proposes collection of network icons libraries and a lot of Network Topology Diagram examples, samples and templates which were created at ConceptDraw DIAGRAM software specially for Computer Network Diagrams solution. There are six basic types of the network topologies: Bus, Star, Ring, Mesh, Tree, Fully Connected. You can fast and easy design professional-looking diagram for each of them using the ConceptDraw DIAGRAM tools. There are plenty of web Visio-like diagramming software available. Web based diagrams software can be powerful, but sometimes it is essential to have desktop software. One of the most advanced diagrams tools like Visio for Mac OS is ConceptDraw DIAGRAM app.
