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.

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

Metropolitan area networks (MAN). Computer and Network Examples

Metropolitan Area Network combines local networks located within a city, and is based on high data rate compounds, implemented on the basis of fiber channels and other digital data transmission channels. Now, with the increasing number of network communities, wireless local area networks based on 802.11b standard are combined into a wireless metropolitan area network consisting of affordable antenna systems and consumer-grade wireless equipment using 802.11a and 802.11b standards.

UML Diagram Types List

Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.

Star Network Topology

The Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment.
Use it to draw the physical and logical network topology diagrams for wired and wireless computer communication networks.

Entity Relationship Diagram Examples

Create an Entity-Relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.

ConceptDraw DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram(ERD) solution from the Software Development area supplies the ConceptDraw DIAGRAM with icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

Personal area (PAN) networks. Computer and Network Examples

A Personal area network (PAN) is a computer network that is used for data transmission between different personal devices (computers, telephones, digital devices, etc.) and for connecting to the higher level network and Internet. PANs can be wired with computer buses (USB and FireWire). A wireless personal area network (WPAN) can be made using the network technologies such as Bluetooth, IrDa, UWB, Z-Wave, ZigBee, Body Area Network. 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 handsets.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Personal area network.

ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM.

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.

Network Security Model

Creation of well thought-out network security model will effectively help you in realization your network's security. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Network Security Diagrams Solution from the Computer and Networks Area of ConceptDraw Solution Park lets fast and easy design all variety of network security models: Open network security model, Closed network security model, Restrictive network access model.
