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.

Hybrid Network Topology

This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
This is example of the Hybrid network topology.
Network topology is the topological structure of the computer network. There are many types of the network topologies: bus, star, ring, mesh topology, but the most popular is the hybrid topology.

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

Structured Systems Analysis and Design Method SSADM is the method which is used at projecting and analysis of information systems. SSADM is based on the data flow diagrams. At the description of data flows out of the system and into the system DFD, which denote boundaries of the system, are used.

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.

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 PRO using the Computer and Networks Area of ConceptDraw Solution Park and shows the Personal area network.

Network Security Model

Creation of well thought-out network security model will effectively help you in realization your network's security. ConceptDraw PRO 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.

Network Security

The Internet is a giant computer network which connects computers all over the world. It is integral part of human society and business. But the serious question for network engineers, designers, lawmakers and enforcers is the need for protect the Internet networks from the Internet crimes, hacking and attacks. There are quite a number of hardware, software and physical methods of protection against them.
The samples you see on this page were created in ConceptDraw PRO using the tools of Network Security Diagrams Solution for ConceptDraw PRO software. They show protection networks with Firewalls and other network security devices.

Entity Relationship Diagram Examples

Creating 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 gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.
