Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.

Local area network (LAN). Computer and Network Examples

A local area network (LAN) is a devices network that connect with each other in the scope of a home, school, laboratory, or office. Usually, a LAN comprise computers and peripheral devices linked to a local domain server. All network appliances can use a shared printers or disk storage. A local area network serve for many hundreds of users. Typically, LAN includes many wires and cables that demand a previously designed network diagram. They are used by IT professionals to visually document the LANs physical structure and arrangement.
ConceptDraw - Perfect Network Diagramming Software with examples of LAN Diagrams. ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Local Area Network diagrams.

Venn Diagram Examples for Problem Solving. Computer Science. Chomsky Hierarchy

A Venn diagram, sometimes referred to as a set diagram, is a diagramming style used to show all the possible logical relations between a finite amount of sets. In mathematical terms, a set is a collection of distinct objects gathered together into a group, which can then itself be termed as a single object. Venn diagrams represent these objects on a page as circles or ellipses, and their placement in relation to each other describes the relationships between them.
The Venn diagram example below visualizes the the class of language inclusions described by the Chomsky hierarchy.

Example of DFD for Online Store (Data Flow Diagram)

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Diagram of a Basic Computer Network. Computer Network Diagram Example

What is a computer network? This is a set of devices and systems that are connected to each other (logically or physically) and communicate with each other. This could include servers, computers, phones, routers, and so on. The size of this network can reach the size of the Internet, and can consist of only two devices connected by a cable.
This sample shows the connection scheme of the home WLAN equipment to the Internet.

Context Diagram Template

This template shows the Context Diagram. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Block Diagrams Solution from the “Diagrams” area of ConceptDraw Solution Park.
The context diagram graphically identifies the system. external factors, and relations between them. It’s a high level view of the system. The context diagrams are widely used in software engineering and systems engineering for designing the systems that process the information.

Hierarchical Network Topology

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 Hierarchical network topology.
A Hierarchical network topology interconnects multiple groups that are located on the separate layers to form a larger network. Each layer concentrates on the specified functions, this allows to choose the right equipment for the layer.
